I have been playing battle.net on lutis just fine, but when i try to install epic games it says "There is a problem with your graphics card Please insure your card meets the minimus system requirements and that you have the latest drivers installed"
My card is an amd radeon rx 5700 xt
There are some extra packages in the AUR, one mentions amd, could that help?
