RTX Remix Shader Compatibility Testing

The repository includes a script to reproduce RTX Remix shader compilation issues locally.

Prerequisites

Build Slang in Debug first:

cmake.exe --preset default
cmake.exe --build --preset debug

Usage

# Run RTX Remix shader compilation test
./extras/repro-remix.sh

# Clean existing dxvk-remix clone and start fresh
./extras/repro-remix.sh --clean

What it does

• Clones NVIDIA RTX Remix repository to external/dxvk-remix/
• Comments out Slang in packman config to prevent overwriting
• Replaces with your Debug build
• Compiles all RTX Remix shaders with SPIRV validation enabled
• Verifies shader compilation output

When to use

• When RTX Remix nightly CI workflow fails
• To test Slang changes against a large real-world shader codebase
• To reproduce shader compilation issues before fixing them

See extras/repro-remix.md for detailed documentation.

Interactive Workflow

1. Check if Slang is already built in Debug (build/Debug/bin/slangc exists)
2. If not, build it first
3. If $ARGUMENTS contains --clean, pass --clean to the script
4. Run ./extras/repro-remix.sh and monitor output for failures
5. If failures occur, help the user analyze and fix them
