8800 GTX performing better than GTX 460

I get a 105 FPS in Furmark on Xtreme burn (512x512) with the 460, 53 FPS with the 8800; but in Bad Company 2, the 8800 kicks the crap out of my 460 with frame rates averaging between 45-60 and reaching peaks of 75, where the 460 barely manages peaks of 40. Same type of deal in Just Cause 2 and Mafia 2. These are with identical settings. (actually a slightly higher resolution with the 8800! 1360x768 instead of 720p)

My full system:

Intel Core 2 Duo e6700 @ 3.4
Crucial Ballistix DDR2 @ 1066, 4GB
600w PSU
Asus P5-KPL-CM mobo
Windows 7 Pro 64 bit

I've done some pretty major overclocking to the 460 (1024/2048/2100 with a voltage of 1.212) and I'm wondering if perhaps I've damaged the card? I've also tried resetting to factory clock settings and that doesn't help, literally no change in performance in any game.

I had intended on doing some benchmarking on the 8800, but when I cranked up BC2 and saw its substantial lead over the 460 I was quite shocked...

I'm also running the 460 with HDMI. Could that be the problem? I havne't tried standard DVI or VGA.

I spent 200 bucks on this card not 4 months ago and I'd like to think that a recent card can beat out a card from '07...nothing against the 8800, of course.

I'm fairly confused here, although I'm suspicious of my PSU. It's about a year and half old now so it may be losing power.

EDIT:
SOLUTION!

That is quite some overclocking... Why not keep it in stock settings until you get it to run stable first?

Firstly, BFBC2 doesn't like Dual cores for some reason. You will see substantial increases in framerates when running an i7. Mafia 2 is also strained by the strength of the CPU. Just Cause 2... not so much but you'll also see some difference with a better CPU.

I wouldn't entirely blame your PSU because even if it's getting weaker, a GTX 460 is no more demanding than an 8800GTX. Could it possibly be a connector issue? Are you using two 6-pin PCI-e connectors without the use of any converters? There MIGHT be some damage done by the high voltage on your OC. What temperatures do you get when running the card?

The 460 should be noticably faster than the 8800GTX. I presume the 8800 is 768mb? And the 460 is 1GB? Please confirm.

PSU should have nothing to do with this problem - the 8800GTX was a tremendous power hog, the 460 is not, and if the psu were a problem it would manifest itself differently.

@skolpo
I hear you on the Frostbite engine being terrible on scaling to dual cores, and I understand the advantages of an i7 and I'm upgrading soon, but how does that come into play when the system is unchanged except for the video card?

My temperatures with those overclock settings never pass 70 in games, because usage doesn't pass 50%. In Furmark I get 99% usage and the temps reach 90+, but I shut Furmark off when the card reaches 94. I figure this is fine because the max temp is 104.

My PSU has a pair of six-pin connectors, so no adapters here.


@Twoboxer
You're correct on the vram sizes. I figured the 460 should use less juice because of the smaller die size. That's why I'm so confused...the 8800 has a 90nm lithography, fewer cores, slower memory, slower fillrates...slower everything!

Why in the world would a Fermi perform better on stability tests but worse on actual gaming?!

Perhaps BFBC2 was running at DX9 with the 8800 and now is running at DX11 with the GTX 460? You can set it to run at DX9 (google method) and see if it compares better...

BFBC2 probably auto starts in dx11 mode for the gtx 460, and either dx9/10 there are both in this game. Force dx9 with the gtx 460 , google how to do it.

Try AVP dx11 benchmark, I notice my sli setup uses 95% of both cards with that test.

I have had BC2 forced to DX10 for while, and the 8800 has DX10 support.

I had a pair of 880GTXs in SLI until 6 months ago . . . I think I'm still sweating . . .

Anyhow, we *know* the 460 is faster - that's fact not rumor. And the 460 isn't being slowed in any way by having less memory - it has more. So that seems to leave three possibilities:

- The 460 is doing more work, so less FPS (graphics settings somewhere).
- You have a driver issue from going back and forth.
- The 460 is broken . . . a little :)

I reckon I'll do a driver clean and re-install.
I'll edit when I get some results.

OK there may be some scripting and config files that other users have found to be bugged or just out of date that caused issues when moving over to Fermi cards that result in poor performance. If that doesn't help and you got the time do a fresh install plus it will clean out the crap that the os collects.

probably a settings thing. you probably have aa, vsync or something enabled in the driver which is slowing it down. My other guess is the CPU is not letting the gtx460 perform to its peak at such a low resolution. Try crank up the AA to the max and make sure the game is set for dx10 to give the cards fair competition and test them again.

@nforce4max

So instead of re-installing the whole game I wiped the config files in Documents/BFBC2, and that helped tremendously. I'm running the game on max settings, 32x AA, 16x AF, DX11, w/ HBAO @ 1360x768 (poor native res on this TV) and getting average fraps way above 30. When I get around to murdering my wallet for the i7 and the Sabertooth board I'm confident I'll be rocking at 60 fraps.

I had also done a driver clean/re-install but that barely made a difference. The biggest thing was wiping the configurations, so if anyone is experiencing the same issue with Fermi cards, go to \My Documents\BFBC2\ and delete everything that's there (backup first!!!). Thanks a bunch to everyone for their help!

I'll look at Mafia 2 as well, maybe I'm missing something. Just happy to have my favorite game running well.
