7970 Ghz low framerate?

Hi experts,

Long time Tom's Hardware reader - first time poster.

I've just upgraded my GPU to go with a new 2560x1440 display, but the results are underwhelming. I picked up an HIS IceQx2 7970 Ghz edition. Did the whole driversweeper thing, and installed the newest Catalyst Control Center. Fired up Metro 2033, cranked it up to the highest, and was stunned to average 20-30 fps. According to the benchmarks here, I should be getting minimum 40, but closer to 50-60.

At work now, but I know that I've got:
8GB Ram
650w of power (supercooler, I think)
i5-2500K @ 3.30Ghz 3.60 Ghz
Gigabyte H61M-S2-B2 motherboard

There shouldn't be a bottleneck there, should there?
Anyone have any ideas? If you need more info, I can give more details when I get home.

Cheers for the advice!

    That sounds about right. Metro 2033 is a very demanding game at 1080p, never mind 2560x1440. Here is a benchmark for that card at similar resolution for Metro 2033:



    Looks like your 7970 is performing just as it should. Here is the full review with more benchmarks if you're interested. http://www.techpowerup.com/reviews/HIS/HD_7970_X_Turbo/

    Hope this helps!
  2. Hi Zero Cool,

    Thanks for the reply. That's interesting that Techpowerup has the average fps at only 24. The benchmarks here on this site report very different numbers. At the same resolution, they show 51 with 4xMSAA and 61 with AAA:

    What accounts for the much higher framerate on this site, or am I missing something?

    If I can only get 24 out of the 7970 Ghz, I kind of regret upgrading from a 560ti. I thought it was going to be a much bigger step forward (granted, I've gone from 1080p to 1440p).

    Thanks for your advice!
  3. different sites may have different in-game settings and benchmark different levels of the game, so you get different results. play around with your game detail settings, and make sure physx is off or on low, without a nvidia card, physx is done on your cpu, which is slow.

    Wow, that is strange and a huge discrepancy! Here's a couple more charts:





    I don't know if Tom's Hardware screwed something up but those frame rates would be tough to achieve with crossfire'd 7970's at that resolution on max settings. That being said, the 7970 is still a huge upgrade from a 560 Ti... Probably close to 200-250%. Gaming at 2560x1440 really taxes graphics card though, compared to 1080p you'll get about 1/2 the FPS.
  5. Some of those benchmarks are using high settings, some of them are using very high settings. I don't think any of them are using DoF or PhysX which would lower FPS even more. A LOT more.

    Then there is the benchmark software provided with Metro 2033, which is far more demanding than most any place in game. Some sites may use their benchmark, while others may use there own in game sequence.
  6. Thanks for all the replies. I'll tinker around with it a bit more this evening, and see what I can come up with. I did notice that Tom's benchmark is High, not Very High, so that'll probably make a huge difference, and I'll try to disable Physx.

    Cheers!
