Interesting GPU usage while playing or playing + recording

post #1 of 2
Thread Starter 
Hi, so I noticed that my GPU usage is pretty much 99% while playing BF3 (1680x1050), but since I am getting decent FPS I didn't think it's something relevant. Then I tried to record some games with MSI Afterburner, and while recording, my GPU usage dropped to about 80%. How could this happen? My BF3 settings were unchanged and I had Afterburner set up for 4 threads, since the other 4 were used by BF3 mainly.

i believ its because while you recording afterburner is making your cpu bottleneck because you only have 4 threads instead of 8, therefore, your gpu doesnt have to run at full speed because you woudnt gain any fps
