RTX Remix Shader Compatibility Testing

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

Prerequisites

Build Slang in Debug first:

bash

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

Usage

bash

# 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

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