GTX 660 low GPU load/utilization?

post #1 of 13
Thread Starter 
Q6600 @ 3.4 Ghz
MSI GTX 660 2GB OC (306.97 drivers)
Windows 7 64bit

I have Power management mode to prefer maximum performance.

Teamfortress 2: CPU-44%, GPU-22%, 120fps
Guildwar 2: CPU-53%, GPU-48%, 40fps
Left4Dead 2: CPU-68%, GPU-70%, 90fps

I upgraded from a HD4670 which it's GPU load was always 99%.
Don't really think my CPU is bottlenecking my GPU. Why is my GPU load not reaching near 90's. Is it the game or nvidia's drivers?

To be honest mate the games you're running aren't going to stress your card that much. Download furmark and stress it with that, in addition you can get 3dmark06 I think it is and bench with that.

Certainly with those levels of CPU usage (Pretty much 100% on half your cores) I would say it is your CPU holding you back. But those games aren't particularly demanding either so I wouldn't expect full GPU utilization on that CPU.

To be honest depending on his revision of the q6600 he might be able to overclock it a bit more, 3.8 or maybe at a push 4. That would help out a little bit.

You do have a slight issue with your CPU not being able to keep up with your GPU however the upgrade was worthwhile.

I see over 100 fps on GW2 and 90-99% gpu usage so yeah it's probably your CPU.
Did you clean un-install the AMD drivers properly?

In TF2 it looks like you've got a 120Hz screen with Vsync on.

If Vsync is on then that GPU load is fine.

However GW2 doesn't look right at all, unless it's capped at 40FPS.

Sorry, but you did remove your ATI card didn't you, you're not using it to power another monitor or something are you.

Your CPU is holding you back from max GPU usage. However, those fps are just fine, pump up the eye candy to make the GPU usage go up.

Yea upgraded from HD4670 to GTX660 it was a big leap even if you guys say my CPU is bottlenecking. Was only able to play those games at low/medium settings on the old card. Those GTX660 #'s was ran at fullscreen borderless 1680x1050 all maxed out settings, full eye candy. I suppose those games only really make use of 2 cores. I have G0 Q6600, I've heard people pushing 3.8ghz, but that's pretty high and hot. I only have a 500w Antec PSU. I suppose it sets me up for a Core i7/mobo maybe during blackfriday sales.

Don't bother with an i7, just stick with a nice i5 2500k, you might be able to find one in the for sale section here. I do remember seeing one recently.
