NVidia 250 GTS + Windows 7 x64 = performance problem?

Hello all,

I have recently purchased a new system with:

1) CPU: Intel Quad Core Q9400
2) Graphics card: NVidia 250 GTS Graphics card by GainWard
3) RAM: 2GB (677 mhz only, inherited from my last system, will be replaced soon by 4GB 1033 mhz)
4) OS: Windows 7 64 bit
5) Power: OCZ StealthPower 600W
6) Mobo: GigaByte EP45-UD3LR

I'm not sure what the graphics performance SHOULD be, but I believe is should be better than what I'm getting.

Unreal tournament 3 gives me 40 fps tops, and when the screen is full of details and characters, the frame rate drops to 16, and even 6 (!) sometimes.

I checked UT3 recommended system requirements and it seems my system surpases them. I tried dropping the detail level and resolution, but it doesn't help.

I believed that it may be a driver issue, so I tried 195.62, 191.07, and 186.18, but to no avail.

I should point out that my problem is not UT3 specific, and I'm just giving this game as an example.

I installed 3DMark vantage, and found out that the average framerate in the GPU tests ("performance" setting) is 17-18, and that my GPU score is 6155.

Can anyone with a similar system (especially folks with 250 GTS & windows 7 64 bit) tell me of the performance he/she is getting, and wether my worries are justified?

Assuming they are, does anyone know of a solution ot what to check for next in order to pin point the source of the problem?

Thank you very much in advance,

  1. Hmmmm......

    What resolution are you playing at? Detail settings?

    I have a Q6600 and GTS 640mb on Windows 7 x64 and I play everything just fine at 1920x1200.

    Well, at first I set it to high at 1680x1050, but when I saw the FPS, I tried lowering the detail and the resolution, but I'm still not getting a good speed.
  3. Did u connect the 6pin power connector for your card?
  4. Yep, sure did.

    I have my suspision that the card is not getting enough juice (from my 600W power supply), but how can I verify such a theory?
  5. hi, I'm not sure if you have already solved your problem or not, but to verify your theory you would have to check the 12V current rating on your power supply. does it have split 12V or just one rail? and what is the rating on the one or both combined? 600W in total should be enough to power your system, however if there is not enough power on the 12V then that will cause a problem. I believe the GTS 250 requires a minimum 12V current rating of 24A.

    More like 10 or 11amps, a 12v rail with 15A would more than suffice.
