RTX Remix Runtime 1.2.4 Release Notes:

New Features

• RTX Remix Particle System: Remix now includes a path-traced particle system, allowing for realistic VFX in over 165 games. Path tracing particles is a rarity in games, giving Remix particles the unique ability to cast real time lighting, shadows, and reflections. Remix supports two workflows for adding particles:

  1. Make particles while you play: From the Game setup tab of the RTX Remix Runtime, tag any texture you see as a “Particle emitter”. Then, define global properties for particles to change how they animate (Rendering Tab > Particles). This is great for prototyping or implementing a handful of particles in your mod. See an example in this video.

     Note: the texture driving the look of these particles will be the same texture emitting it.

  2. Author particles in the Toolkit: Add particles to any prim, load particle systems from USDA files, a trail system for advanced visuals, and new controls for collisions, velocity, rotation, and color range. You can also adjust parameters directly through the GUI.

• Change particles however you like: the look, size, quantity, light emission, and physics, including turbulence and gravity–It’s easy to start making particles, with a lot of controls to master.
  

• Settings Clamping: We added support for clamping in RTX Options, which means developers can set valid ranges for settings. This prevents you from entering invalid or out-of-range values, making configuration safer and more user-friendly.

• SPIR-V Shader Compilation: The shader compilation process now generates SPIR-V directly from Slang, enabling support for new shader functionalities like cooperative vector intrinsics for neural shading.

Performance and Memory Optimizations

• Improved Build Stability and Speed: We've improved Remix project build stability and reduced compilation times.
• Better Rendering Efficiency: The renderer now has more robust calculations, fixing several sources of invalid values throughout the pipeline.
• Efficient Resource Management: Remix now tracks replacements for instances and lights, which lays the groundwork for future features and more efficient resource management.

Image Quality & Compatibility

• Order-Independent Transparency: Remix now supports order-independent transparency, which greatly improves how it handles scenes with many overlapping, alpha-blended objects like smoke or foliage.
• Expanded Bloom Effect: You can now control the blooming radius (with the rtx.bloom.steps option) and we've increased the maximum number of bloom steps from 5 to 8, allowing for a wider, more expansive bloom filter effect.
• Vertex Color Improvements: We've improved the vertex color support for the emissive channel.
• Vertex Capture Precision: We've improved vertex capture by performing the perspective divide earlier, significantly increasing precision in games that rely on vertex shaders. This makes new titles like OutRun 2006: Coast 2 Coast more compatible.
• System Information Logging: Remix log files now include system details (CPU, memory, OS, etc.) to help with various actions including diagnosing and categorizing user issues more effectively.

For Developers/Contributors

• Improved Shader Compilation Logging: Runtime shader compilation now outputs to stdout/stderr, so you can see the output directly in the IDE debugger.
• Unified Global Time System: A new unified global time system ensures consistent timing queries across the code.

Community Contributions

• Ignore Baked Vertex Color Lighting: Thanks to @watbulb (NVIDIAGameWorks/dxvk-remix#99), you can now ignore all baked vertex color lighting in vertex processing via the rtx.conf file (rtx.ignoreAllVertexColorBakedLighting). This simplifies workflows for games with inconsistent baked lighting, removing the need to manually tag many textures.

Bug Fixes

• Rendering Fixes:

  • Fixed an issue where users couldn't create materials with controllable emissive parameters for alpha-blended objects.
  • Fixed a bug where emissive materials from USD files would only be emissive at runtime if they specified a non-default intensity.
  • Fixed an issue that prevented some texture categories from being applied.
  • Fixed flickering artifacts and unexpected image scaling in certain games when DLSS-FG was enabled.
  • Fixed an issue with volumetric atmosphere incorrectly centering around the origin instead of the camera.
  • Fixed a bug where a BLAS (Bottom-Level Acceleration Structure) wouldn't update, causing geometry to remain fixed in place.

• Stability & Crash Fixes:

  • Fixed several rare crashes in the RTX Neural Radiance Cache, including a race condition and a regression where switching presets failed.
  • Fixed a rare use-after-free bug related to replacement instance objects.
  • Fixed a crash that could occur when a replacement light was overridden by an unrelated game light.
  • Fixed a crash in a corner case where different draw calls shared the same object and transform.
  • Fixed several Vulkan validation errors to improve stability.
  • Fixed crashes in the light manager by ensuring the debugger UI doesn't access deleted lights.
  • Fixed a crash when the number of replacement prims attached to a light changes.

RTX Remix Runtime 1.0.0 Release Notes:

DXVK:

• DLSS4: multi-frame frame generation, transformer model for ray reconstruction
• Neural Radiance Cache (NRC): a live-trained AI approach that estimates indirect light more accurately and performantly
• RTX Skin: ray traced subsurface scattering support, using the RTX Character Rendering SDK.
• RTX Volumetrics: higher quality volumetrics with more detailed light shafts. RTX Remix runtime now exposes variables to manipulate atmospheric characteristics, with presets (heavy fog, mist, smoke, etc.)
• Volumetric light intensity multiplier: enables modifying volumetric contribution on a per light basis. (Note that this is not a physically-based parameter and may cause odd visuals if the contribution is biased too far away from the original physical quantity.)
• New Texture streaming system: optimizes VRAM usage to maximize texture quality within the available video memory budget
• USD GeomPointInstancer support: reduces CPU cost for rendering many copies of a replacement mesh. This improves performance when rendering props like grass, where many instances of the same object are typically used.
• Various performance improvements and memory usage optimizations:
  • 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

  • More reuse of compatible resources' memory across different rendering passes
  • Used VK_BUILD_ACCELERATION_STRUCTURE_LOW_MEMORY_BIT_KHR on lower memory GPUs
  • Tweaked RTXDI quality settings for more performance when RayReconstruction 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
• Improved Ray Reconstruction responsiveness with animated textures.
• 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
• Updated NRD to 4.13 for better performance, sharper and more stable denoising
• animatedWaterTexture now works for translucent materials
• Fixed flickering in reflection & refraction rays that hit the sky

    • We added GitHub Actions for per commit bridge builds to produce debug, debug optimized, and release packages. In most cases the release package should be used, but the other two can be helpful for logging additional information and creating crash dumps when trying to troubleshoot certain issues.
    • Added extra logging to debug builds that help understand the nested command flow of longer D3D command sequences, which makes troubleshooting issues a lot easier.
    • We also now log a list of the most recent client and server bridge commands in case of a crash to help with troubleshooting.
  • Bug Fixes and Stability:
    • Fixed various issues where the bridge was not handling D3D input or behaving the same way as the system D3D runtime, which led to changes in rendering behavior that could cause crashes, hangs, or visual glitches. As a result games will run much more stable now.
    • Fixed an issue where a game might ask for an impossibly large buffer size to be copied. Now, in those situations, buffer size will be kept to a maximum limit.
    • Fixed an edge case that could cause the bridge server to exit prematurely under certain circumstances.
    • Fixed issues with reference counting for textures and surfaces, which could lead to instability and crashing.
    • Fixed an issue where releasing a D3D volume with a parent texture could lead to a crash.
