9800GTX+ / 9800GT (PhysX) in game screen stutters and skips

So I've been trying to solve this problem for the last month or so. Nothing worked so now I'm askin gyou guys for help. Here is what happens, when I play Heroes of Newerth, the game skips frames whenever I'm walking, whether I have 60 fps or 125 fps. Sometimes, the screen freezes and the audio stutters between 5-10 seconds ever 20 minutes or so (it hasn't happened in a while so I don't know if I still have it). I fold on my 9800 GT in the background but I doubt it does anything to the gameplay because when I stopped folding, the game stutters still occur. My nvidia control panel settings are all reset to stock settings. I oc'ed my 9800 GTX+ but it's been stable under 24 hours of GPUTOOL stress test. My CPU is also OC'ed but is stable under 50 linpack tests and 12 hours of prime. I don't know if those have to deal with the problem at hand but I'm still throwing it out nonetheless. Even at stock settings on the GTX+, the game still stutters. I'm currently using 196.21 driver of nvidia for this card. Let me know if you need any more information.

  1. Please post your complete system specs and make sure you have the latest Nvidia drivers installed.
    Also i know your OC is stable but if you can reset your OC's and test.
  2. Oh, I thought I did already. Here they are:

    GA-EP45-UD3P Rev#: 1.6
    Bios FD
    Intel Core 2 Quad Q8200 2.33GHz @ 3.12 GHz
    Freezer Pro 7 Rev.2
    G.Skill PC2-6400 4x1Gb DDR2-800 (5-5-5-15 @ 2.0)
    EVGA 9800 GTX+
    NVidia GeForce 9800GT (PhysX)
    Corsair 650W
    Antec 300
    Win7 Ultimate 64x

    I've installed 191, 195 and 196 and clean sweeped before each installation with driver sweeper in safe mode. I've tried stock oc, didn't work. I've tried 9800gtx/9800gt, 9800gtx/8600gts, and 9800gtx by itself and it still didn't work.
  3. I don't suppose your internet connection is dail up or you have a massive lag during that game. Cuz if you're getting above 60fps and getting a stutter on that game not quite sure what could cause that besides lag. imo i'd mess with all the video settings in the game take it off exclusive mode etc just play around with it and see if you can get it to work without a stutter.
  4. I've tried lowest settings, vsync on/off, all extra settings off, AA off, etc etc. Still stutters. I'm on college network which is T3 so I doubt lag is the issue.
  5. Test without a PhysX card,i mean one test only with a 9800GTX+ and then with a 9800GT(don't use either as a PhysX card)
  6. Ive tested with just the gtx and it still didn't play well. I'll try the gt tomorrow
  7. still didn't work. I reformatted my computer also and that didn't work
  8. ups
