With my XFX8800GTS I get an enormous drop in framerate after playing 10minutes or so.

    (It strikes me that I couldn't find much info here on this subject, or didn't I search enough ?)
    Anyway with my newly bought XFX8800GTS, after around 10 minutes gaming (e.g. Oblivion) my framerate drops from 50-50fps to 10-15fps.
    It is definively not a power or heat issue (Zalman 600W psu and 4 case fans, gpu temp around 75-80*C under load) and I have tried all kind of things, including disabling Turbocache and changing some Bios settings, but nothing helps.
    In other forums I found numerous threads on this subject - apparently many other 8800GTS owners have the same problems - but no solution yet. The only temporary fix seems to be to Alt+Tab out and in the game again, but that solves it only for another 10 minutes or so.
    So I was curious if anyone here has found a permanent fix already.
    Or should I go for a complete different card ?

    Yeah had this a bit also with my pair just after installing them. I haven't had it since I manually set the 3d settings in the driver. I have mine at 16x AF, supersampling, 8xSLI AA, AFR1, force vsync... So try messing around with those. I actually was getting the lag when my AA was set to 4x, :S ? , so thats my guess. Like your said you're hardware looks good to me.

    What games do you play? Do all the games lag?

    I am having a similar issue, thus why I am surfing the forums at the moment. My issue happens with BF2. Have even dropped the video settings to 1024/768 @ medium quality and have tried different drivers.

    I must say that I mainly play Oblivion.
    With nHancer I already set AA to Off and AF to 8x.
    I also disabled Turbocaching with RivaTuner as was suggested in some other forum threads, but didn't help either.

    I'm sure in most cases its a driver issue or driver conflict with previous driver files.

    In BF2 make sure to erase previous video optimization files in My Documents > Battlefield 2 folder I believe its in the 'mod' folder. That may help.

    Did you use some program to erase the previous drivers, like 'Drivercleaner' ?

    Maybe you should try AA and AF because the card can handle it.

    Because I also bought a new cpu and mobo, I did a clean install of Windows XP and the NVidia drivers (the latest 158.22), so that can't be the problem.
    Maybe my card can handle AA, but wouldn't there be a chance that the problem only increases when I enable it ?

    Well that would make sense in our brains but come on this is programming. The reason I say this is because I had my SLI in 4x AA (going along with your thinking) and it was worse but then I put it to 8xSLI and it works amazingly. Just mess around with the driver. It might just be something to do with Oblivion, have you patched the game?

    I have the same problem in oblivion, I couldn't figure out what was causing it, and someone suggested disabling my onboard sound, and with the sound off the fps drops went away. Obviously you shouldn't have to play without sound, so I've emailed bethesda, but they still havn't given me a solution yet.

    I've tried using a different soundcard but it still happened, so it must be some kind of conflict in the Direct3D/audio, but as of yet, I'm not playing oblivion.

    Yes, I have patched it.
    From various threads on other forums I understood that it also happens with other games, not only with Oblivion.

    It sounds like a memory leak problem - the memory gets full and WIN starts swapping. Try looking for increased HDD activity when the FPS drop begins.

    yeah i heard this memory leak theory aswell but i did everything i possibly could ( formatted hd , tried a diff one , tried every possible driver , tried on xp and vista, used some riva tuner tweaks ...).
    This just seems hopeless, guess im just gonna return it and try getting a 640 mb version but what if it happens with that aswell lol ?

    i recently finish fear extraction point, ghost recon advanced warfighter and stalker without any single problem (except that i had to run GRAW with compatibility mode ir order to avoid some game random crashes). have you downloaded all available windows updates, directx 2-month updates (maybe try installing directx10 also)...just a suggestion.
    for mobo and video card drivers install only WHQL versions and not beta to see if it solves the problem.

    I made two changes last night and played BF2 for hours with no issues.
    Changes were installed Z-tweaked V158.19 drivers and changed fan to 100 percent via RivaTuner.

    Maybe I am speaking too soon, because I haven't yet played long enough, but I returned the XFX8800GTS and exchanged it for a EVGA8800GTS (basic, not overclocked model) and it looks as if the problem is gone. I played Oblivion for half an hour, walking through dense forests, and apart from a few stutters when entering a new area, the framerate stayed above 40fps, sometimes even above 60fps.
    Keep my fingers crossed but it looks as if the EVGA is less sensitive for this problem as the XFX.

    I read that it also happens with the 640MB and even with the GTX, although it takes a little longer.

    An yes, I used only the official WHQL drivers and have the latest mobo drivers.
