8800GTS 320mb Fps problem!

Hey I have an eVGA 320Mb in Vista Home Premium 1680 x 1050 resolution (stock at the moment... waiting on Rivatuner 2.05 :D) and I have a problem playing some maps at full detail without getting some weird FPS but huge FPS hits (~30-40 FPS) around some areas in the map De_dust2. I haven't tried it out on HL2 but I think I will tonight. I believe it could be a problem of running out of VRAM or faulty VRAM because Overclocking the core and the memory did not seem to help with this problem.

More about 8800gts 320mb problem
  1. Ive got the same card/cpu/ram and it fooly SMASHES HL2.
    Maybe a driver issue?
    Maybe vista issue?
    Uninstall/reinstall etc. Ive also heard atl tab and do good things sometimes.

    Re HL2... giving it another bash ATM. Set v-sync on, limits fps to 60.
    However if i do a quick load it halves to 30 :/
    If i load again it fixes.
    Odd. Otherwise maps like dust etc should get smashed by an 8800.
    Lack of vram is not an issue imho.
  2. It is definitely not a driver issue, I've installed multiple drivers (including beta ones) and they all have the same problem. I'm hoping it's either a map issue or a game issue or a fixable vista issue. I don't really want to reinstall Vista =/. 'Retry' ing the server seems to help a bit but the fps drops are still there around pit and in T spawn.

    Also sometimes the FPS drop(it stays around 20-25 FPS or so) holds constant for other parts in the map and then suddenly goes away when i get to certain places, but not always such as around 'side' and in 'middle'.

    I don't know if it is possible to reinstall a particular map or if I should just reinstall the entire game, Office seems to work just fine, Haven't tried a whole lot of other maps.

    On a side note I'm only able to overclock my VRAM to about 850 or so or else I start to get artifacts. Core Clocks fine. I'm definitely going to step-up one of these days though. Might as well use the feature if I have it, right?

    Anyway, I'll post my problem on the Steam forums see if i can get anything there.
  3. Stupid question but did you remove the old drivers before you installed all those new drivers?
  4. Yes I did but I only used add/remove programs to remove them, I suppose I could try driver cleaner...
  5. Hi guys,

    I have a dual boot of xp x86 and vista x64 with 4gb ram and a 8800gts 640mb.

    Even with the last beta drivers, all my games in vista at 1680x1050 will lag at same settings as xp x86.

    I tried BF2 and HL2, both lag in vista. I did not try to install MOH Airborn or COD2 after seeing this.

    I keep my xp for gaming until vista is good for gaming.
  6. djbrad007: Using a 64-bit OS for gaming in general, at present, is basically a Bad Move, Vista or XP.

    Valtiel: I'd be leaning toward it being an issue with the game you're playing, especially if you're playing online...
  7. Sounds like it might be the dreaded 8800 slowdown bug. It is a texture management problem that happens on all 8 series cards, but the 320MB version gets hit hard by it because of its lack of VRAM. I have an eVGA 320MB 8800gts and I was having this problem like crazy. I almost sent it back, but the newest drivers have fixed it (although only in DX9) for me.

  8. Well I think, I'll just throw money at the problem and step-up to a GTS 640Mb. Its only about a $50 step-up and my current GPU's VRAM sucks at overclocking anyway (can only get up to ~860) which is a huge downer for me :(. Or i might even get a GTX but I'm leaning towards the GTS :p

    I agree that you should get a much better OC on your VRAM than that. I'm at 950MHz and it's not even hot. I've gone up to Ultra speeds but I have no need for that so I stick with my cool 950.

    As for the step-up, if you wait a bit longer you may be pleasantly surprised by g92 in November. If you don't feel like waiting then I see no harm in upgrading to a GTX :pt1cable:
  10. u geting this same issues in SP mode? if not its server side. If so...are you making sure that in game resolution and desktop res are matched- i had lag spikes on 2142 when not matched....and just an fyi- I have a 640 and it crushes everything atm- ran bioshock demo like a champ as well.
    good luck

    If its the evga step up, it only lasts 90 days

    Good point, I am well aware of that as I bought my GTS in early August, so my step-up will expire just days before the supposed release of g92 :(
  13. 30 days left on my step-up program so I won't be able to wait =(

    hopefully I can find an extra 100$ or so lying around, I want to crush crysis :D

    That changed from a $50 step up to a $100 step up pretty quickly. Are you sure you're not loggin in to some phishing site?
  15. Sorry, I wasn't very clear I said "an extra $100" because I would like to step-up to an 8800GTX (its not actually a $100 its actually about 250 :( ) Vs. a GTS 640 but I don't know if it would be worth spending that extra $250 dollars so I'm hoping I come across some cash sooner or later. Or I might sell my card on ebay and wait for the next wave of cards, be it 8900 Series or 9800 series :D
