Debugging AMD-Specific Issues with Driver Experiments Tool is a July 2025 article on asawicki.info about using Driver Experiments in AMD's Radeon Developer Panel to diagnose vendor-specific graphics bugs.
After setup steps for the Radeon Developer Tool Suite on recent Radeon GPUs, the post focuses on two experiments. Force NonUniformResourceIndex can expose missing NonUniformResourceIndex or nonuniformEXT decorations that often glitch only on AMD. Disable color texture compression helps attribute missing barriers, clears, or Discard-style initialization on compressed render targets. Shorter notes cover FMA fusion, DXR shader inlining, and structured buffer stride mismatches.
It is for advanced DirectX 12 and Vulkan developers debugging AMD-only artifacts who can run RDTS. Familiarity with descriptor indexing, resource states, and barriers is assumed.
The article is free HTML with setup steps and references to GPUOpen docs. Experiments apply only while the panel runs and need an app relaunch to change.
It is useful as a debugging playbook that turns opaque AMD-only failures into testable hypotheses about nonuniform indexing or texture compression metadata.
