using "--use-d3d11" gave worse performance on Nvidia, DX12 works miles better. I've read DX11 is only needed for AMD RX7000 series cards for this title. Proton 9.0 fixes the white pixel border in windowed fullscreen, and fullscreen works without black screening the game on initial launch if you did not change it back plus a performance boost.

Able to play on Native rendering with mostly everything on high with the exception of some subjective settings like bloom, motion blur, depth of field, and ambient occulsion disabled at 80-100fps consisentantly.
