I was able to install SC just fine but when I run the game thru lutris I get a pop up reporting that "Star Citizen requires DirectX features level of 11.1 as a minimum which is not supported at present on this machine.". If I understand correctly, DirectX isn't actually installed on linux and is rather "emulated" in some fashion so I'm not quite sure what to check. I'm running Mint 20.4 with a Radeon RX580 and the latest which is supposed to support DX 12. apt show amdgpu reports I'm running version 21.50.2 driver (if I'm reading this right).
