    Default Graphics Blues! - The Jitter Bug...

    Hi Everyone,

    I am having a very strange graphics problem. I just installed an nVidia eVga 6800 AGP into my ASUS P4C800-E. I am running a P4 2.4b, Corsair 512M PC3500 stick, Audigy 2, 2 x WD 120G 2mb HD's, Antec True Power 550W, Dell 2001FP Monitor. Before this nVidia card, I was running an ATI 9700 Pro and was experiencing the same problem with that card. I did a fresh Windows XP SP2 install with this new video card, latest Intel chipset drivers, nVidia drivers and all the latest XP updates. I have also tried several older Forceware drivers.

    The problem I am having is jittery, jerky, ghosting graphics not only happening on my desktop but in games as well. When I scroll through text or images in IE, Firefox, Word, etc... the movement is not smooth and is stuttering/ghosting. As well as when dragging a window across my desktop. It gets worse the faster I increase the movement or scroll. If I move the mouse super slow it is nice and smooth with no jitter but as soon as I start to speed up the movement is starts. It not only happens with the mouse but also with the keyboard arrow keys as well. So it is not mouse related. I'm running a Logitech MX1000 and have tried switching back to my old corded Microsoft Optical just to confirm this. This problem was happening even before I upgraded to my new MX1000 when I was still using my Microsoft Optical. I have also tried using my MX1000 on both the USB port and PS/2 port with no impact on this issue. So for sure it is not mouse related.

    It's similar to a Vsync tearing, but the text, image, or window has a blurring effect that is jittering or ghosting while its moving and leaves a bit of itself behind that has to catch up with itself. Where with only a Vsync tear you get the stepping tearing but not the blurring that I am getting. When I'm in a game like BF2 or Americas Army, when I turn with the mouse or strafe with the keyboard objects like trees, edges of buildings, other players, etc are ghosting and jittery where again it takes a second for the image to catch up with itself, like a graphics lag. My monitor is running at it's native 1600x1200 resolution @60Hz. I run all of my games at 1024x768 and this monitor can do both 60Hz and 75Hz at the resolution. I have tried both and still get the jitters.

    I have so far replaced my mobo with another brand new ASUS P4C800-E running the latest BIOS. Heat is not an issue, I am not overclocking and processor and GPU are running cool. CPU 32-Idle / 38-Load - GPU 49-Idle / 53-Load. I swapped out my Corsair 512M for a Kingston 512M stick and even tried running with 2 Kingston sticks for a total of 1 GIG RAM. Replaced the P4 with a different P4 2.4b. I replaced the power supply with another Antec 550W, tried another Audigy 2, tried another CRT monitor, replaced both WD Hard Drives and replaced all the IDE and floppy cables. My eVga 6800 is hooked up to a power molex with nothing else connected to it except the video card and I have confirmed that my Antec 550W PSU's voltages are tight on all the rails.

    I have replaced almost every part of my rig except the case which is a good quality Antec Performance II tower, and my optical drives, one is a Pioneer DVD slot drive and the other is a Pioneer 16x DVD Burner. I also disconnected all of my 80MM case fans to see if they were causing some kind of interference. And disconnected my two optical drives. As well as disconnecting all the case wiring leads like speaker, LED, reset switch, etc and only left the power switch lead connected to the mobo. Has anyone ever heard of a case causing this issue?

    I also tried running another OS using the Knoppix Linux 4.01 Bootable CD version and the jitter/ghosting was even happening under Linux. So that definatly rules out any problems with Windows XP.

    What's really weird about this issue is that my stytem used to run great, no graphics jitters and smooth like silk. Even when I had my ATI 9700 Pro in it. Then all of a sudden one day several weeks ago it started having this problem. I thought that it may be graphics card related, and anyway it was about time to upgrade my card so I thought that would fix it.

    To this point I guess I have eliminated just about everything I could think of that would cause this problem. This should not be happening, my 2D scrolling and dragging and my 3D movement in games should be smooth without jitters/ghosting. This problem really has me stumped.


    Does anyone have any suggestions or have you seen this issue before?


    Many Thanks

    Mark

    Wow Mark! You've done a LOT of troubleshooting on this - you must be ready to pull your hair out!

    The fact that this is happening on a Knoppix CD as well tells me that it is:
    a) your AGP slot
    b) your video card
    c) your video cables
    d) your monitor (although you tested it, try it again with another monitor and make sure you use all completely different cables)
    e) interference

    The first thing I would do is dig up an old PCI video card (or use the onboard video is available), or borrow a friends' PCI video card. Hook it up with your current monitor and see what's up.

    Next, I'd try a friend's AGP video card.

    If it STILL is happening, next, I'd use a completely different set of video cables.

    Then, swap out the CRT.

    Finally, if nothing else works, bring the PC to a friends' house or your work/school. Hook it up and see if you still get the problem. Who knows? Maybe there's some weird kind of electrical interference in the house?

    Good luck!

    Hi Oscar,

    I tried all of the above and still the problem persists. And yes your right I have several handfuls of hair to be sure

    Here is a small fraps video from a game that clearly shows this problem. Look carefully at the edges of the boards on the window and the edge of the roof as I move. First part of the video I am moving with the keyboard, then with the mouse.

    It's not working for me.
    I know everything about nothing, nothing about everything and precious little about the bit in between.

    Hi Mark - Presumably you have visited this forum dedicated to your graphics card? http://www.evga.com/community/messag...?TOPIC_ID=3976
    Commonest issues seem to be -
    1. 2D and 3D clock speeds should be set the same.
    2. Dedicated power supply to the graphics card.
    Needless to say, there are plenty other issues also. :cry:
    Regards
