Horrible FPS 40% compared to normal

Not sure where to start on this one. I noticed my game was running slow so I checked the FPS and it was half what it normaly is. So I ran 3mark 03 and scored 36994. When I first put this card in, I scored 51705 on 5/20/09. I have since uninstalled the 185 drivers, reintalled 182 drivers got the same results, uninstalled GTX 275, reinstalled 8800 GTS with 185 drivers. Since I first ran 3d mark 06 before I took the 8800 out, I checked that. I originally scored 11700 on 5/20/09, this time I scored 6216. I checked EVGA Precision and the clocks are going up to where they are supposed to on the line gaph. I do not think it is the video card, but do not know what else could be killing my FPS. Other than FPS and games, the comp is running fine. Any help would be much appreciated.

I just ran 3dmark 06 with GTX 275 and scored 6309. 2 weeks ago I scored 13215. That is only 93 points higher than 8800GTS


My system is,
Intel Core 2 Duo E8400 Wolfdale
Gigabyte Ep35 Ds3p
4 gigs Gskill ram
GTX275 896 mb
Audigy 2 sound
Corsair TX 750 PSU
Windows Vista 64 home premium
 
3DMark06 and 3DMark03 are so CPU bound that it will not challenge enough your GTX 275 and will score almost the same as your old 8800GTS. Try to use Vantage or a challenging game with a built-in benchmark like Crysis or Far Cry 2 and see the difference.
 
But they did show a huge difference. on 1-25-09 I ran d303 with 8800GTS and and scored 39090. On 5/20/09 I ran again with GTX 275 and scored 51706. I noticed this problem with Americas Army (not a major graphics game) and the FPS were 50% of normal. Normaly i am in the 90-100 and now I was 50 to 60.
 
Perhaps you have something running in the background eating your CPU time a lot? Check your task manager. Are you running an antivirus? Perhaps there was a recent update that broke the engine on your installation and it's eating your CPU too? Or you have an unwelcome guest on your system (something that's eating your CPU)? Run antivirus and spyware scans. Cause from your description it seems it's GPU independent (both your GTS and GTX score around half of what they used to).

EDIT: Also, what HDD are you using? A dying disk could hinder performance too.

"I ran 3mark 03 and scored 36994. When I first put this card in, I scored 51705 on 5/20/09."

Something obviously went wrong and it's not because he didn't use Vantage. And if he didn't use Vantage 'before', how is it going to help him now when he has the problem? He has no previous Vantage score to compare to.
 
What changes (software or hardware) have you made to your PC since 5/20/09? If any.
Have you overclocked anything?
 
The card is still in 16x I checked Riva tuner. The card is idle at 48-50c and goes up to 58 during game. I noticed this problem after I installed Vista SP2. I couldnt figure what else would do this so I uninstalled SP2. I still have the same problem now with SP1.

the HDD is less than a year old. Other than FPS the comp is running fine.

This is my guess. Whenever I notice a performance hit, it's usually a card running at x1. Definitely check the link width with CPU-Z or GPU-Z.

Edit: I see you already checked this. Your temps look good, too. I wonder if there are known performance issues with SP2. I haven't heard of any.

Can you lock your PCIe frequency to 100 or 101 in BIOS? Might want to try that.
 
I just tried running America's Army (again by no means a GPU hog) in lowest settings and there was no difference. The FPS bounce from 40 to 90. Orignially it was always 90 or above on highest settings. The 8800GTS was exactly the same, 90 or above in highest settings.
 
Try reinstalling/upgrading your other drivers aswell, especially chipset drivers and audio drivers.
I had problems with my onboard audio after installing SP1 on Vista, and again after installing SP2. It really slowed down my PC, and made the audio choppy and garbled.
With SP1 it was enough to deinstall and reinstall the audio driver. With SP2 I had to download a newer version to solve the problem (uninstalling SP2 didn't solve my problem either).

Might sound like a long shot, but who knows, it might help.
 
If you see the fps "bounce", I suspect either some weird throttling issue (despite acceptable GPU temps), or that you have some background process eating up cycles. Definitely monitor CPU usage and temps.
 
just played 10 min of America's Army CPU temps were according to Real Temp 3.0, 47 and 56 and 58 it is now down to 40.

weird but the FPS is now stable at 90. I changed nothing and have been at this since yesterday. I will now run 3d03 again.

ok now I have no idea. I just ran 3d03 and have changed nothing and scored 51933. that beats my old score over 200 points. The core temps went to 58c. I am happy but i have been woking on this for over 5 hours and in 5 minutes it all went back to normal with no change by me. anyone have an idea why this hiccup might happen?

virus scan software doing a weekly scan in the background?
 
It sounds like the 275 was running in the throttle mode when it wasn't drawing enough juice from the psu.
Keep an eye on the psu. ie. fan running etc.

PSU is way more than adequate for his setup.
 
It was probably a virus scan in progress when his score was low. And its not the CPU that can't handle virus scanning, although it most certainly will take a toll on the CPU. Its the hard drive that gets turned into hammered sh#t.
