[Updated/Solved - Open Source Driver is awesome! :)] AMD is useless for gaming
Dota 2: 10-20 fps + severe input lag (settings do not matter) TF2: 20-30 fps + severe input lag (settings do not matter) Unigine Heaven: up to 40 fps in Basic mode Xonotic: 70 - 120 fps on low settings
System: Ubuntu Gnome 13.10 Phenom II x4 B55 @3.1Ghz AMD 7770 1Gb + drivers from repo and AMD website (tested both) 1440x900@75Hz monitor
This is ♥♥♥♥♥♥♥♥.
P.S. Vsync is off.
It seems that after all latest RadeonSI (open source driver) and kernel 3.13 are the♥♥♥♥♥♥ After all my initial problem with those two was DPM, which I thought I set up correctly, but hey, I'm just a human :)
What u need for 60fps (when Windows gives me 80 in same scenario) in Dota 2 at max settings with card like 7770:
