GPU Usage and bottlenecking

post #1 of 15
Thread Starter 
Ok so I have an interesting question to put in front of everyone....


If I have vsync on,

and my GPU usage is less than 100%

BUT my FPS is less than 60

does that mean that I have a cpu bottleneck,

or not enough ram? Or maybe this is a driver related issue?

Games I see this scenario sometimes are Homefront, BC2, Crysis 2, Dragon Age 2.

I noticed this because I started using a monitoring program that shows FPS. DX version, GPU Temp, and GPU usage percentage.

Turn off V-Sync. You won't need it unless your having issues with the screen image.

I leave it on in all my games... If I have it off and the FPS is above 60 it gives me a headache

vsync removes the tearing if your using a 60hz monitor.

EDIT: Its not a bottleneck if your capping it your self by enabling vsync

Huh? So you want the V-Sync on and get 60+FPS? V-Sync adds more work to the GPU. I don't run it at all.

When you say less than 60 fps, what is it averaging at and in what games and what drivers are you using?

yes but he could have other settings that aint right, cause if i put metro on dx11 it strains my gpu bad but on dx9 or 10 its fine even he might have his aa up too high (doubt it with a 570) but it could be possible he is getting a bottleneck somewhere,
thats why he posted here. also i thought you only get headaches (for some people) if they put the monitor hertz up, cause i cant play on a 120hz monitor cause it screws up my eyes but a 60hz is fine and i dont run vsync because i feel it runs better
