    Hello,

    Since getting my rigs a few months ago I've been getting game stutter/jitter/jearks.
    This doesn't seem to be consistent on all games though.

    The lasest example I have is Crysis, it runs 40-60 FPS at 1280x1024 with Very High settings + vsync, but I keep getting this jerkiness when I start to move, usually seen as the ground beaneth me is not moving right.
    This problem is pretty hard to explain, and the fact this rig scores just right on 3dmark tests doesn't help

    convince anyone that there's a problem anywhere.

    Has anyone experienced this on a similar rig?

    Any insight would be appreciated.


    My Spec:
    CPU: AMD Phenom II X4 940 BE
    MOBO: Gigabyte MA790X-UD4
    RAM: A-DATA 2x2GB DDR2 @ 1066
    GPU: Sapphire 4870 1024MB Toxic (Factory OCed, Catalyst shows: GPU: 780Mhz, Memory: 1000MHz)
    PSU: Enermax Pro+82 625W

    Try disabling vsync - that may help. Crysis isn't exactly system friendly either.

    Otherwise it usually bad PSU, lack of ram/Paging File issues..

    Thanks for replying.

    Turning vsync off just makes it tear without getting rid of the problem.

    My PSU is certified to work with this kind of system, and I actually got it replaced once.

    I have 4GB ram, and I usually don't see any HDD activity while playing.

    I had a problem like this - same game and same symptom - it had to do with a RAM setting in the CMOS.

    How could you get screen tearing? Surely you're not getting more than 60 fps in Crysis with all high settings....

    @ Mike Z- Can you elaborate?

    @ Pillmonster - I turned some of them down to High, only 3 maybe.
    Benchmarking with Fraps with vsync game me a minimum of 42 and a maximum of 62 fps.

    I believe I disabled the dual channel setting. The computer has two 1 GB memory sticks. They were operating at 128-bit when Crysis stuttered. They're operating at 64-bit now and Crysis runs smoothly.

    That's weird about the dual channel.

    My BIOS is currently configured to Dual Unganged mode...

    Kinda weird - I mean - the computer I'm talkin' about has two different brands of 1 GB memory sticks, so, I guess they don't operate well in dual channel mode.

    Let me clarify about my problem: the stutter/jerkyness happens randomly, a few seconds of smoothness, a few seconds of stutter.

    I just played a Crysis mod called City Assult, and it ran really smooth, then I went back to a multiplayer map and got stutter again.

    Inconsistent? I'll have to lower the settings and see.

    You don't have Cool n Quiet or anything similar enabled that could be throttling you cpu do you?

    Well, I do have Cool n Quiet enabled... but I haven't seen it throttling down the CPU.

    I guess I'll have to test that as well.

    Get two or three 5870s and watch your systems fly!

    Well, a SSD would increase performance as well, particularly in the minimum fps front. I noticed that a lot of jerkiness in Crysis dissapeared with an SSD. Very High has huge textures, and an SSD can stream textures like none other.

    I'm going to have to try that RAM thing, switching it to non dual mode...
    I know for a fact that my sticks didn't come in a kit, but on separate packages... long shot.

    Anyway, another problem that plagues my system is the occasional frame loss in youtube/flash videos.
    When the sound streams just fine, but sometimes it's like the video jumps to a later frame, making a jaggy transition.
    That's the only way I can explain that.
    It may only happen in firefox, I'm not sure yet, but I am sure that there's nothing loading my CPU, GPU or HDD.
    Are you guys familiar with such a phenomenon?
    I've never seen it happen on my older rig (Athlon 3500 Single Core, 1GB RAM, nV 7600gs).

    Gonna have a busy weekend when I finally test the RAM and switch my GPU with the old 7600gs to see what happens.

    lol at the above, well i cracked a smile, which has been a first for today.

    The ram thing could be it, i know i had gaming problems when i starting mixing and matching in Dual Channel mode, and they are all sorted now.

    Oh, and you don't need to get over 60fps to get tearing, it'll happen just cause its out of sync with the screen, not that Crysis is particularly bad with it.

    Back.

    I tried running the Crysis with only one memory module at a time and still got the same result.
    For example, Farcry2 runs without a hitch.

    Annoying.

    Btw, my damn stock CPU cooler is really starting to piss me off noise wise... my rig becomes a vacuum cleaner when stressed.

    I should get an after market cooler to ease the pain...

    May you give me any recommendations?
    Thanks.
