I have an issue with Low CPU/GPU usage in games. Below my system specs:
4930k (tried stock and currently @4.6)
x79 deluxe mobo
dual ATI 6990 (stock and tried small OC).
Running Win 8.1 with all updates
PSU corsair AX1200 (I had one Evga 500w 80+ so added it for CPU and motherboard, nothing changed)
Tried disabling HTT, c1 and all c in bios, speedstep, thermal management.
System set to high performance
Issue is that in BF4, all my CPU and GPU usage is quite low on any settings, BF4 graph shows
constant spikes on both GPU and CPU, showing GPU as one bottlenecking.
Usually all 4 GPU usage is around 35-70 % (All GPU have equal percentages)
All CPU is less then 40 %. Tried different drivers ATI, from13.4 to 14.7 with clean uninstall.
I have installed other games to test if this is only BF4 performance.
Divinity- all GPU running at 35%-50%, 30-40 fps
Archage 2- on 2d screen I am getting full GPU usage- 99% on all cores and 400 fps, when it loads 3d character screen and later in game- 35-40%, 30-40 fps
Watchdogs- 2d screen again all GPUs used- 300 fps, later game unplayable with 30-50% GPU usage and 20-30 fps
I am playing in 1440p and most games are set to ultra quality, but changing quality does not change GPU usage.
Any ideas? Or is it just old GPU quad crossfire scaling?
