Apparently the "AI" you asked to make this bugreport doesn't know that AMD's windows vulkan driver are often broken with vkd3d-proton, especially the old ones available for Polaris GPUs. This is almost certainly a driver bug.
This isn't a setup we can support. Windows is uninteresting for vkd3d-proton anyway, and Polaris hasn't received driver updates in years and will not work with current code in the first place.
d3d11.dllx1 2026-06d3d12.dllx1 2026-06d3d12core.dllx1 2026-06dxgi.dllx1 2026-06
Running Helldivers 2 through DX12→Vulkan translation (vkd3d-proton) on native Windows produces persistent texture/material corruption on specific asset classes. The corruption manifests as:
Wrong textures applied to armor, weapons, enemies, and (rarely) ship features ("killzone" text from unowned armor sets displayed on player character — see screenshot 2)
Dense black/white material noise ("sandpaper") on armor, weapons, enemy models, and mannequins
Cape/cloth assets displaying incorrect colors and pixelated noise overlaid on correct geometry
Transparency artifacts on some assets
Unaffected assets: floors, ship walls, large static environment surfaces, ceiling geometry.
The corruption appears immediately on load, is largely static on the model, does not shimmer with camera movement, and persists across sessions regardless of shader cache state. Deleting shader caches has no effect.
Ultra supersampling reduces severity, suggesting a LOD/derivative calculation component (opinion of claude and chatgpt).
What works correctly:
Native DX11 — no corruption
Native DX12 — no corruption
DXVK DX11→Vulkan — no corruption
What is broken:
vkd3d-proton DX12→Vulkan — corruption always present
The wrong-texture symptom strongly suggests incorrect bindless descriptor heap indexing — the engine is sampling from an adjacent heap entry rather than the correct texture slot for the equipped item (opinion of claude and chatgpt).
