7970 Low GPU Usage

post #1 of 3
Thread Starter 
Hey.

I recently finished my build and everything else seems, and is fine, expect i get low GPU usage.
This appears most of games, ex. (Arma 2, Minecraft, MW3, MW2, NFS Most Wanted, CitiesXL 2012 etc..)
However, not in every games. Example Battlefield 3, Medal Of Honor, Dirt 3- 2 & 1.

The GPU usage in those games is around 40% but it's traveling from 20% to 90% a lot.
CPU usage seems to be around 20% in those games, and people who will tell me that CPU is bottleneck, i can say that i7 series is not bottle necking anything. I know that even core i3 should be enough in most games. Also yes, i have v-sync off.

I also have tried clean driver installs, including beta versions, and they give no difference to me.
Also i'v tried even re installing Windows and I was so despaired I even tried Windows 8... (shh.. don't tell anyone...) Still, no difference.
Disabling Hyperthreading, or seting CPU run max clock rate with disabling turbo boost tech.

Other things that I'v tried is overclocking, CPU Overclocking doesn't help, but overclocking GPU the results are pretty impressing as we know 7970 does it well. Performance boost is class 10-15 better FPS, but still usage is same half.

In benchmarking, 7970 gives solid 99% and results are what we can expect from this devil. It does around 15% better than average 7970.
Windows performance score gives max 7.9 both graphics.




My rig:

GPU: Gigabyte AMD Radeon 7970 ghz- Edition
CPU: Intel core i7 3770K
PSU: Corsair CX 750 W
RAM: Corsair Vengeance 1600mhz (32Gb)
HDD: OCZ Vertex 3 & 3 other storage HDD's
Mobo: Gigabyte B75 D3H
OS: Windows 7 Ultimate x64






Please help i can't wait i can get full power out off this beast !
Ask if you need more information !

Those games are console ports, they aren't using much gpu because they were made to run on hardware that is 1/5th as powerful as a 7970.
Minecraft runs in java, which is mainly CPU based and not GPU intensive unless you get alot of graphics mods in it.
Cities XL doesnt use much gpu because it is a city sim, and has to run on alot of different hardware to reach the proper audience.

BF3 and the dirt games will use much more because they are PC based and BF3 and dirt3 use DX11.
hope this helps answer your question thumb.gif

So is that really normal and it's caused by the game optimization ?
Only games that just wont run so well is Arma series, and Mc, and they both are known cause of bad optimization..

Thanks for that answer, it was helpful !
