RTX Remix Release 1.0 Notes (3/13/2025)#

We are excited to announce the official 1.0 release of RTX Remix.

Note: From now on the Toolkit version will follow the runtime version (1.0.0) and they will continue to be released together.

RTX Remix comes out packed with new state of the art graphical features to empower you to build more beautiful worlds and characters in your mods. And the runtime has been upgraded with new neural rendering with DLSS 4 and Neural Radiance Cache to improve the experience playing Remix mods. DLSS 4 Transformer model ensures everything you create will retain more detail, allowing your artistic vision to translate more perfectly to the screen. With Multi-Frame Generation, path traced mods soar up to 8X performance over native. And, RTX Remix debuts the world’s first neural shader, Neural Radiance Cache–an AI approach to estimating indirect light more accurately and performantly, that trains on your live game session as you play.

Let’s get into the details:

Improved RTX Remix Rendering#

DLSS 4 Multi-Frame Generation: DLSS 4 allows you to generate up to 3 frames per rendered frame, supercharging performance. In Half-Life 2 RTX, DLSS 4 MFG helps increase framerates by 10X over native at 4K, ensuring the game looks smooth no matter what bells and whistles you turn on.

DLSS 4 Ray Reconstruction Transformer Model: Ray Reconstruction has a new Transformer model that is much more accurate at accurately denoising ray-traced images, ensuring the highest degree of detail is retained. With the new Transformer model, even lower DLSS presets can look as good as higher presets with the old “CNN model” (Convolutional Neural Network). The image will be more temporally stable and overall much more enjoyable.

Please note, the Transformer model is a slightly heavier network than the CNN model. As a result, we’ve opted to automatically default to the CNN model at the “Low” and “Medium” presets to ensure people who are looking to claw back any performance on the table can secure it.

Neural Radiance Cache: NRC is a neural shader that estimates more accurate indirect light more performantly. While you play, a grid of tiny neural networks in world space train live on your game session, tailoring their approach to the content you are seeing in real time. The Remix pathtracer traces an extra, smaller set of long training ray paths that record radiance observed at each bounce to train the NRC with. Regular per-pixel ray paths then terminate earlier, generally at 2-3 bounces, at which point an indirect radiance from a multitude of additional bounces is inferred by AI. Because fewer bounces are calculated for the vast majority of ray paths (and are instead inferred), NRC improves performance in Half-Life 2 RTX by 15%.

It offers three graphical settings with tradeoffs between performance and indirect lighting accuracy: Medium, High, and Ultra.

Performance & Memory Optimizations: The RTX Remix runtime has seen a number of optimizations to performance in both CPU bounded and GPU bounded scenarios. The extent of this uplift may vary depending on the specific RTX Remix mod. Take a look at how performance is improved in Portal With RTX on a 5070TI:

Portal With RTX (Beta Runtime): 111 FPS
Portal With RTX (Release Runtime): 132 FPS
Portal With RTX (Release Runtime with NRC On): 155 FPS
Portal With RTX (Release Runtime with NRC + DLSS): 260 FPS

Performance and memory optimizations come on the back of a multitude of changes: Optimized memory and performance of BVH builds by utilizing instancing Limited max bones per vertex for skinned meshes Improved OMM budgeting to work better in scenarios using most of VRAM Added runtime normal compression for replacement assets to reduce memory usage Removed unnecessary resource allocations based on active graphics features Disabled rendering passes that are not needed for active graphics features Improved reuse of compatible resources’ memory across different rendering passes Reduced memory usage of ray tracing acceleration structures on lower memory GPUs Tweaked RTXDI quality settings for more performance when Ray Reconstruction is enabled Switched from host visible to device local allocations for mesh replacement buffers Optimized CPU cost of CreateSurfaceMaterial by caching and reusing RtSurfaceMaterial within the same frame Reused instance matching and projection decomposition to lower per instance CPU cost

New Texture Streaming: Optimizes VRAM usage to maximize texture quality within the available video memory budget. Players will notice assets streaming in faster, in higher quality more often, and will see “spilling” less frequently. Note: this will not necessarily decrease total VRAM usage, as RTX Remix always tries to use available VRAM efficiently to ensure highest quality textures are being seen.

Changes to Shader Compilation Remix will now only prewarm shaders that are actually being used, improving shader compilation time at first launch. Note that this may lead to shader compile stalls when changing Remix options that require different shader permutations. Added asynchronous shader compilation functionality and a progress UI when the game is compiling shaders during play

Upgraded Mod Authorship Tools#

New Features#

Enhanced Character Creation: In games that support GPU skinning, you will now be able to replace characters in the same fidelity you have been replacing assets and world materials. Import a rigged character replacement into RTX Remix, and from the Toolkit, remap its bones and joints to help it conform more closely to the skeleton RTX Remix captured (and therefore expects to render). Once this is done, the character will animate as expected.

A new tool has been added to help with replacing animated assets using GPU Skinning.

More information about the skeleton remapping tool is available here.

Controls for RTX Skin: RTX Skin represents one of the first implementations of sub-surface scattering in ray-traced gaming. Light can now propagate and transmit through skin, grounding characters in a new realism. RTX Skin can also be used to make dazzling world materials, like jade, which can sparkle and take on complex colors when illuminated.

Use the RTX Remix Toolkit to add SSS maps to any asset to tune the per pixel transmission level. And in the RTX Runtime, you can adjust the SSS scale to influence the global multiplier for all assets marked with SSS to increase the intensity of the effect.

More information about subsurface scattering is available here.

RTX Volumetrics: We’ve overhauled our volumetric system by leveraging a volume-based ReSTIR algorithm (Reservoir-based Spatiotemporal Importance Resampling). Light beams now look more defined, with higher contrast volumetric lighting and shadows. Shafts of light will look sharper, helping to create those epic moments in gameplay we love.

Within the RTX Remix menu you can adjust parameters to customize the volumetric atmosphere of your mod. We provide presets so you can visualize your game scene with fog, smoke, haze, and other conditions, and each parameter is tunable. You can even inject dust particles in the scene, and define their physics and properties.

In the RTX Remix Toolkit, the volumetric radiance scale attribute can make lighting larger than life (literally), influencing how much light contributes to the volumetric look of your scene. This multiplier enables modifying volumetric contribution on a per light basis to create more pronounced lighting effects. A 1 value keeps lighting completely physically based obeying the laws of physics, but you can turn it up or down for a more stylized look.

Stage Manager#

The most requested feature is here and it’s sure to speed up your modding. From this new control panel, modders can view a complete list of all tweakable game elements, jumping directly to them with a click. Sort and find prims, lights, meshes, materials, skeletons, and more, isolate remastered and original assets, and create custom searchable tags for any prim, making finding and editing assets easier. You can also view prims by Remix category, like particles, decals, UI, sky.

You can also temporarily hide assets in the Viewport, in the event you are modifying a game scene that is obstructed by walls or large objects. And multiselection and editing is even easier when all of your assets are groupable in a list.

Stage Manager Official Release: The Stage Manager is now integrated as a key component of the RTX Remix Toolkit that allows selecting and editing of any prim in your mod.

ON by default: The Stage Manager is now on by default, but can still be toggled under “Optional Features”.

New Stage Manager Tabs: Added Categories, Skeleton, Meshes, Materials, and Custom Tags tabs alongside the existing All Prims and Lights tabs to Stage Manager.

Custom Tags: Tag any capture or replacement prim with a custom name and make it easy to find again or manage similar objects.

Contributions Welcome: Stage Manager functionality can easily be expanded by contributing to our open source project.

Refined Toolkit Experience#

The Toolkit has had a thorough polish pass making it much easier to use.

Updated to kit sdk 106.5: The app is now built on a new version of the omniverse kit sdk which contains many fixes and stability improvements.

Removed Path Restrictions: Removed whitespace project path limitation for flexible project names and locations.

Performance: Improved performance and responsiveness of Stage Manager and other widgets.

New Homescreen: A redesigned home screen with a simplified project creation flow brings a cleaner interface to making new projects. Added ability to cleanup deleted projects.

Improved Packaging: Added a new tool to help automate resolving resource paths when packaging your mod.

More information about mod packaging is available here.

Property Widget Improvements: Continued to fix, improve the look and feel, and simplify code controlling selection panel and property editor widgets.

Remix Categories: This key feature of Remix has been updated in Toolkit and aligned with the Runtime. We’ve foregrounded tooltips to help guide Modders in tagging replacement meshes with the appropriate category for the runtime.

More information about Remix Categories is available here.

Ingestion Scale Factor: Flipped asset ingestion parameter from “Meters per Unit” to “Asset Scale Factor” to make ingesting assets at the right size more intuitive.

RTX Remix Release 0.5 Notes (4/30/2024)#

With the latest update of RTX Remix, we’ve enabled modders to add DLSS 3.5 Ray Reconstruction for Remix mods. Look below for our detailed release notes, and for a full changelog, please click here

As a reminder, you can update RTX Remix by clicking the menu next to the “Launch” prompt on the RTX Remix Application page of the Omniverse Launcher.

RTX Remix Toolkit Release 2024.3.0#

Features#

Added a new “Teleport” action to teleport any selected object to your mouse cursor or the center of the screen. Teleport via the viewport sidebar or the Ctrl + T hotkey.
Added a new “Waypoint” feature, enabling modders to save camera positions as waypoints and snap the camera to them. Waypoint options can be found in the top right corner of the viewport. By default, opening a capture will save the camera starting position as a waypoint.
Added DLSS 3.5 Ray Reconstruction to the Viewport
Material/object property panels can now be pinned for any selected asset, keeping them locked into view even after deselecting the object. This enables interesting workflows–for example, selecting a wall and locking its material properties panel, selecting a light near the wall and locking its object properties panel, and being able to simultaneously adjust the wall and light in relation to one another.
Added the option to unload the stage to reclaim resources without closing the app. This function is useful if you need to free up memory to do certain actions (for example, boot the game while running RTX Remix, or run RTX Remix’s AI Texture Tools). This option can be found in the top left menu.
Rearchitected AI Texture Tool and Ingestion processes to allow the RTX Remix Toolkit to run efficiently in parallel with them. Modders should have a much easier time multitasking while ingesting or AI enhancing assets.

Quality of Life Improvements#

ESC key now unselect all objects
Added sliders for all material and object properties
Closing RTX Remix with unsaved data will now present a save prompt, so that modders do not lose any progress. Also streamlined UX for going between open and saved projects.
Added a refresh button to the capture list, and improved thumbnail pop ins to be less disruptive
Grouped several material properties that lacked a parent category into their own “Other” category
Updated default light intensity values for all newly created lights to be much lower. Newer default behavior should pair better with more games.
Project creation now creates symlinks
Made several improvements to accessibility, text legibility and text clarity

Bug Fixes#

Attribute and material properties now properly behave with object selection and deselection
Fixed issues with material properties pane changing unexpectedly when using undo and redo functions
Fixed various responsiveness issues with the ColorField/color selector
Added headers to the capture list to help explain captures and replacement progress
Fixed crashes with the AI Texture Tools when processing DDS files

RTX Remix Runtime 0.5.0#

Note to modders–with RTX Remix Runtime 0.5 we have removed an option that was causing excessive ghosting with no benefit to users. If your project requires you to remain on an older RTX Remix Runtime, we advise you to check your rtx.conf file, and ensure rtx.enableDeveloperOptions = false.

Features#

Added DLSS 3.5 Ray Reconstruction to RTX Remix, making it possible for modders to improve image quality with this AI powered denoiser. With ray reconstruction, path traced lights update faster, reflections and thin light detail are more stable, and texture details can pop more. Learn more about ray reconstruction and its benefits for RTX Remix modding in our GeForce article
Added the d3d8to9 wrapper to the runtime release. The d3d8to9 wrapper was an essential file modders had to manually add to their runtime package in order to unlock proper compatibility in DirectX 8 titles. Now, we include it automatically–modders should find highly compatible DirectX 8 games to work better out of the box thanks to this change. This change should not impact non-DirectX 8 titles.
Significantly changed the texture tagging flow, which is essential to properly setting up a game with RTX Remix. We’ve added several new options that should streamline how advanced users interact with these menus. These changes are likely to undergo further iteration, and we encourage any early feedback on them.

We’ve changed how texture tagging works when the “Split Texture Category List” option is toggled on. When “Split Texture Category List” is toggled on, opening or hovering over a texture category selects it (indicated by it turning orange). Left clicking a texture in the gameworld or the category list will automatically assign it to the currently selected texture category. Right clicking a texture in the game world or in the Remix runtime category lists will give users the very familiar texture selection drop down menu to choose from all of the available texture tagging options. Please note, you must have a texture category selected to tag textures in this mode.

We’ve also added an option to only view texture categories that contain textures you have already tagged. You can select this by toggling the “Only Show Assigned Textures in Category Lists” checkbox. When checked, untagged textures will appear in their own “Uncategorized” category

Thank you to community contributor “xoxor4d” (Github PR #49) for submitting the code for this change. We look forward to further improving how game setup and texture tagging works in RTX Remix.

Quality of Life Improvements#

Improved stability and performance in shader-based games by enhancing the vertex capture system
Resolved visual artifacts, like banding, with tonemapper by introducing blue noise driven dithering. To enable this feature in the RTX Remix Runtime menu, go to “Post-Processing” > “Tonemapping” and set “Dither Mode” in the dropdown to “Spatial + Temporal” (uses a noise pattern that changes over time) or “Spatial” (uses a static noise pattern). The config options for these settings are rtx.localtonemap.ditherMode and rtx.tonemap.ditherMode for the local and global tonemappers respectively. These config options can be set to 1 for Spatial dither mode or 2 for Spatial + Temporal dither mode (or 0 to disable dithering).
Added config options to hide the RTX Remix splash banner (rtx.hideSplashMessage = True/False) and to display a custom welcome message to the user on startup (rtx.welcomeMessage = “example text”)
Added option to pass the original game’s cubemaps to RTX Remix’s backend. This enables cubemap textures to be used for tagging. Note that cubemaps will not render correctly, and draw calls that reference only cubemaps are not usable in Remix. To enable this feature in the RTX Remix Runtime menu, go to the “Game Setup” tab > “Step 2: Parameter Tuning” > “Heuristics” and check off “Allow Cubemaps”. Or, use the config option rtx.allowCubemaps = True.
Added the ability to ignore baked lighting associated with certain textures. This is useful in cases where the game bakes out lighting to vertex colors or texture factors (rather than lightmaps). To use this feature, in the RTX Remix Runtime menu’s “Game Setup” tab, as part of the texture tagging workflow, there is now a new category called “Ignore Baked Lighting Texture”.
Added the option to configure various RTX Remix systems that rely on a game’s world space coordinate system (ex: terrain baking) to assume a left-handed coordinate system.

When modding a game with a left-handed coordinate system, you may notice that terrain, even after being properly tagged in the Game Setup tab, still looks incorrect. Open the RTX Remix Runtime menu, and in the “Game Setup” tab, under parameter tuning check off the “Scene Left-Handed Coordinate System” checkbox, and suddenly all of these systems, like terrain baking, should begin to work properly. The config option for forcing these rendering systems to assume a left handed coordinate system is rtx.leftHandedCoordinateSystem = True.

Thank you to community contributor “jdswebb” (Github PR# 65) for submitting the code for this change.
Added an option to use AABBs to differentiate instances, and therefore track them better across frames. For gamers, that means less ghosting and flickering for animated objects and skinned meshes in motion. To enable this feature, open the “Game Setup” tab of the RTX Remix Runtime menu, select “Step 2: Parameter Tuning” > “Heuristics” and toggle on “Always Calculate AABB (For Instance Matching).

Thank you to community contributor “xoxor4d” (Github PR# 67) for submitting the code for this change.
Improved how RTX Remix mods run for Steam Deck and Linux AMD users, thanks to optimizations for RADV drivers.

Thank you to community contributor “pixelcluster” (Github PR #63) for submitting the code for this change.
Improved the consistency of distant lights, making them update properly when changing or reorienting them. This fixes bugs in certain scenarios like when a distant light was parented to a mesh that rotates.

Thank you to community contributor “mmdanggg2” (Github PR #66) for submitting the code for this change, and thank you to “Kamilkampfwagen-II” for reporting the issue on GitHub (issue #49).
Enabled the function logging feature in the RTX Remix Bridge found within the “Debug” build to also be in the “Debug Optimized” build.
Added an option logServerCommands to the RTX Remix Bridge to write what commands the server is processing to the NvRemixBridge.log file. To enable, in the bridge.conf file found alongside the NvRemixBridge.exe, set logServerCommands = True with no leading # mark. If bridge.conf does not exist, you can get it from https://github.com/NVIDIAGameWorks/bridge-remix/blob/main/bridge.conf
Added an additional logging mode that includes the messages of logServerCommands, and status information from the RTX Remix Bridge client/server messaging systems. This can be helpful for catching potential bridge messaging issues. To enable, in the bridge.conf file found alongside the NvRemixBridge.exe, set logAllCommands = True with no leading # mark. If bridge.conf does not exist, you can get it from https://github.com/NVIDIAGameWorks/bridge-remix/blob/main/bridge.conf

Compatibility Improvements#

Made several changes to the RTX Remix Bridge that enhance compatibility across a variety of games
Fixed an issue that would cause certain games to hang. There was a deadlock in the RTX Remix Bridge where the client would be blocked waiting for a shared buffer to be read, thinking that the server was behind, while the server was in actuality caught up and waiting for a new command. The client was improperly telling the server that it had overflowed the shared data buffer because the command sending code was not distinguishing between a pointer with valid data to send (which has non-zero size on the buffer) and a null-pointer (which has zero size on the buffer).
Fixed crashes, graphical errors, and unexpected behavior caused by games running with RTX Remix by stalling the data queue in the RTX Remix Bridge when a write would overflow the queue while the overflow flag was already set.
Improved certain incompatibilities where RTX Remix would close unexpectedly or stop updating the visuals (while audio continued to play). To correct an issue where a command processing thread could prematurely terminate if starved of commands for the bridge timeout duration, RTX Remix Bridge server timeouts are now disabled. Additionally, we now close the RTX Remix Bridge client on unexpected bridge server closure.

Bug Fixes#

Fixed issues with texture capture, capture stutter, and capture corruption in certain titles
Improved reliability of the RTX Remix Bridge build system.
Sped up how quickly the RTX Remix Bridge informs the host game about invalid calls to SetTransform(). The RTX Remix Bridge client now verifies the D3DTRANSFORMSTATETYPE argument for calls to SetTransform(), and in the event the argument is invalid, it returns D3DERR_INVALIDCALL to the caller instead of making a round trip call to the RTX Remix Bridge server and the dxvk-remix component of the RTX Remix Runtime.
