Initial release of NVIDIA RTX Remix Runtime, containing precompiled binaries for the dxvk-remix and bridge-remix repos.

Changelog

Since the latest update of Portal with RTX, the following updates have been made to Remix:

Bridge

• remove dependency on native d3d9 in the bridge

Compatibility

• A complete overhaul of our geometry hashing and processing system. Please note: these changes will enable asset replacements with this runtime to work with the Remix creator toolkit. This release still works with Portal with RTX with certain directory renaming steps (see below) but pre-existing mods that rely on Portal RTX runtime for asset replacement will stop being supported in future Remix releases.
• A new sky handling system which better improves visual compatibility with native rasterization
• Added a view distance feature for fading distant objects improving visual compatibility with raster
• D3D9 TCI flag support for procedural texcoord generation
• Fused world/view transform feature
• Support for implicit swapchains

UX

• Various UX improvements including a simplified graphics settings menu, more tooltips, and highlighting objects in the world on mouse-hover
• Expose more of the texture pickers we used in Portal via the UX
• Improved fallback light controls (for games with no lighting)

Other

• An early prototype of multiple mod stacking support (ex: for modding existing remastered RTX titles like Portal With RTX)
• Temporary removal of DLSS Frame Generation
• CPU Performance optimizations for Opacity Micromaps
• A fix for Chell's hair in Portal
• Lots of compatibility related bug/crash fixes
• Path-tracing image quality improvements (reduced noise & newer denoisers)

Portal with RTX and new runtime

To get Portal with RTX working with the RTX-Remix OSS:

1. Rename 'lss' dir to 'rtx-remix'
2. Add a new dir under 'rtx-remix' named 'mods'
3. Move 'rtx-remix/gameReadyAssets' to 'rtx-remix/mods' (so 'rtx-remix/mods/gameReadyAssets')
4. Rename 'rtx-remix/mods/gameReadyAssets/replacements.usda' to 'mod.usda'
