CPU and GPU not getting utilized by games

Last response: in Graphics & Displays

Hi

I've been noticing while playing GTA 4 (and for some other games as well) that my CPU and GPU are not being used to their full potential.

This causes serious lag spikes during gameplay and makes it less than enjoyable to play.

I notice the GPU (7970 Stock) hovers around 35% usage and the CPU (FX 8150 OC) isn't far off either

Is there anything I'm not trying here? I've read that using certain command lines can help improve performance for the game but have noticed little difference when trying it myself.

I'm open to any suggestions and would lave to see the game ran at its full potential.

-Note-
I'm running the game on medium settings with the View distance at 90, detail distance at 80 and vehicle density at around 75.
Night shadows are turned off

latest drivers as of today's date, Nov/10/12

Thanks in advance :)

I wouldn't think so. If the CPU was bottlenecking the 7970, it should still be at more then 35% util. Almost seems like a bug in the game/OS where its not usually all the modules that the BD has. Any chance you are restricting cores in windows?

I also noticed you said you were running win7 ultimate. I see this a lot, more so then ultimate should be used. I'm assuming you are using a hacked/downloaded copy. Might want to check for virus/rootkit on your OS. If your CPU is too busy running virus then you won't have the power for the games.

If the cpu not used over 80%, i doubt it bottle necked....

I think it's more like bad code/port of the GTA itself....






That is a common misconception, actually gta 4 is utilizing only 3 of his cores worth, he is never reaching 80% utilization but is still bottlenecking because of the FX's terrible single core performance.





It is a bad port on top of that.

The fact is he is leaving a lot of the performance of the 7970 on the cutting room floor because of his cpu.

Thanks for all the help.

I would love to get a new CPU but i dont feel that an i7 ivy bridge would be a worth while upgrade for only 10 frames more performance in games and considering it run hot when OC. would a i7-3930k be a good upgrade? or should i wait for the ivy bridge version?

Secondly how do i go about updating the game when its a steam version? shouldn't it be the latest version?
