No, didn't know it would impact the performance.
I'll do it later today and retest
I expanded the power limit to+50 (Seems to be the maximum). It didn't help.
I game on a television (a LG 60hz 32" lcd). The crimson driver recognized it as a 60hz television.
Also testes an folder game: grid autosport. Max settings 4xmsaa with vsync... around 30fps average.
From the games I played only dragon age inquisition was able to +50fps maxed out 4xmsaa vsynced
1920x1080 is max res of my screen. I can't pick higher res options. But I can see playing around with settings (msaa, post processing,...) doesn't really change the fps a lot.
Only thing that has an impact is vsync on or off. But even then my vega barely touches 60fps @ 1080p.
What can be the causing this, or how can I try to identify the cause?
This is my rig (it's an ITX rig):
CM750 corsair PSU
Peak t°c after benchmarking Rise of The Tomb Raider and Deus ex mankind = 65-68°c
Sidenote: i upgrades from a r9 290. Which was also the first gpu in my rig. I didn't clean install display drivers? Is this possibly the issue?
