CPU at 95-100%, gpu 60-75%, which is the bottleneck?

post #1 of 4
Thread Starter 
Or if there is any bottleneck?
just popped in BF3 endgame and noticed my 4.6ghz 2500k was hitting 100% usage on all 4 cores, while gpu fluctuated between 60-80%. does this mean cpu bottleneck? or since its bf3 mp 64 map meaning cpu is needed more than in other games so this is normal? cos i really doubt a single 690 maxes out a 2500k at 4.6ghz

Well its your CPU, if one thing is at 100% and the other isnt, that pretty much tells you.

i figured it out

i forgot that when the game is vsynced it only draws enough power from the card to max performance,
when disabled, the gpu usage went back to 95-99%,
also the cpu fluctuated from 60-85% usage on the second testing, regardless of the vsync settings. i guess win8 still somewhat buggy, hopefully that sp1 comes soon
