I'm new in LinuxGaming, switched from Win10 to Ubuntu 18.04 few weeks ago.
Now i found out how to use SteamPlay and Proton and i really like the idea!
But my problem is, that i can't start Games with SteamPlay under using AMDGPU-PRO.
My Main game is CS:GO, whichs works perfectly with amdgpu-pro, got 200fps in average.
So, i deinstalled all amd drivers and used mesa 19, now Steamplay Games working nicely, for example Skyrim Special Edition or Catan Universe, but my CSGO Frames droping down to 100 and when shooting and stuff under it goes under 60fps with really lags.
After installing amdgpu again, csgo works perfectly
Can someone help me? I really want to use Ubuntu further!
I am using RX480
