Symptoms

When in battles, frame rates drop to <5, presumably due to this shader compilation error that keeps showing up in the proton log:

88933.747:02fc:0300:warn:seh:OutputDebugStringW L"Direct3D failed to compile VS 'vs40_shadow_4_bones_dismember' in file 'FX/WeightedWithBlood.hlsl'\n\tfull path: 'FX/WeightedWithBlood.hlsl'\n\tError: error X3501: 'vs40_shadow_4_bones_dismember': entrypoint not found\n\n"

The menus and campaign map do not suffer from this issue at all.

Many proton versions have been tried, including GE-proton. Always the same issue.

Reproduction

Start game, go into "Options", then "benchmark", then "battle benchmark".
