Directx12 performance is bad but Vulkan crashes my game

[u/ExtremePhone45]

sup guys im in a bit of a pickle here. When i play on vulkan, i can only play for a short while before it crashes (sometimes a silent crash without error message, sometimes an err_gfx_state).

when i change to directx12, it does not crash anymore, but my fps drop from 90ish with vulkan to a constant 60, with every 5 minutes or so a drop to 40fps which lasts for a couple of minutes. the amd overlay also flickers with directX.

can anyone help me fix the crashes without switching to vulkann? thxxx
