Low Performance on DiRT 3 7970 GHz

[FastGunna]

From benchmarks I have read, I am getting pretty low performance. I'm not extremely concerned because i'm still getting around 50fps average without any dips on ultra, 1920x1080. Im using a 144hz monitor so getting the higher frame rates does make a difference.

According to this bench, I should be getting more than double the FPS im getting. http://www.tomshardware.com/reviews/radeon-hd-7970-ghz-edition-review-benchmark,3232-11.html

I'm getting similar performance to this benchmark however they are running on an eyefinity set up. http://www.bit-tech.net/hardware/2012/06/22/amd-radeon-7970-3gb-ghz-edition-review/5

I do not have Vsync enabled, using 14.4 Beta Drivers. Temps are all normal (65c or less).

Also worth mentioning I get around the same or better performance on BF3 from both benchmarks.

Tom's gets 110 fps

They use 12.7 driver - non Beta. Try the latest non-Beta driver.

I gather they just leave the clocking as is.

Your psu should be real good. But just in case can you also check voltages with HWInfo?

seems strange, with a 7950 I was getting 90+ fps.

I tried the 13.12 and 14.4 non beta drivers, neither of which made any change beyond 2 FPS

The 12v voltages seem ok. 67C aint too bad.

Have you always had low fps on Dirt with your gpu?

I just got DiRT a couple days ago. I havent noticed frame rate issues on any other games.

Then maybe its the game itself. Are there any updates you need to install?

I have it through steam so as far as i can tell its up to date.

Maybe have a look on Dirt forums

I couldn't find anything related to this, however i stumbled across the issue myself. I noticed that switching from 4x MSAA to 2xMSAA pushed me from 70 fps to 150+. So i decided to check CCC to make sure there wasnt anything funny going on there and I guess I had Anti-Aliasing Filter mode set to edge detect, switched to standard, threw all settings to max on dirt and got 112 avg fps.
