Video Jitteryness?
Hi,
I recently bought a 9800Pro for my Dimension 8300 and it is a vast improvement from the 9600XT I got back in January.
I noticed some jitteryness in NHL 2004 and I ran FRAPS and when the jitteryness occurred the FPS dropped to about 60 from 80/90. At this point I had my refresh rate at 85Mhz at 1024x768 resolution.
I have a Samsung SyncMaster 753DF monitor. Does the refresh rate have anything to do with it or is it the card overheating? Or am I just paranoid?
Thanks so much in advance for replies.
Oh and it's a 2.6Ghz P4 800FSB with HT processor.

I have a 9800 Pro and so far it has worked like a swiss watch. Overheating typically causes tearing and artifacts to appear in your games, but not jittering so I doubt your card is overheating. It definitly sounds like a problem with the refresh rates in your games. Try playing a game and checking the monitor refresh rate by pressing the monitor settings on the bezel. What does it indicate is your refresh rate. Although you indicated you set the rate at 75 Hz, your monitor may be overiding your settings.

Well, it seemed to only occur in NHL 2004 and some part of Max Payne 2 (the level where Mona and Max are searching for Corcoran).
I just lowered the refresh rate to 75Mhz and I play at 1024x768 as I mentioned in my original post.
It just seems lately that the card isn't living up to the reviews and hype. In other words, I hope it was worth upgrading from a 9600XT to a 9800Pro.

I've checked and the monitor has 75hz (excuse my previous Mhz) at the desired resolution.
So for sure it isn't my video card? I'm using the new CATALYST 4.5's that just came out.
The fact that it's an R350 as opposed to an R360 has nothing to do with it, right? I'm just throwing out ideas... my apologies if they are a bit silly...

I hate to repeat myself, but are you checking the settings with the monitor's bezel controls with the game running or are you looking at the setting in the operating system's display properties? They may not be the same. If that's been done and your refresh rate is ok did you move all electrical devices including your speakers away from your monitor? Try using a different electrical outlet, preferably in a different room. If you have air-conditioning are another high output electrical househould device take notice if it's running when you see your jitters. To make sure it's not a monitor problem try a different monitor if you have one. If you've done all this the last thing to do is break open your case and make sure your card is seated properly in the AGP slot. Better still if you have another PC, temporarily install your card in it and see if it gives you the same problem. If you've done all this and are running the latest driver it's possible you got a bad card. Get an RMA and exchange it.408

Dude, I checked the refresh rate using the controls on the monitor.
Aside from not being able to install the card in another computer I've actually checked into everything else.
I'll see how it goes. I don't think I'll need to RMA it.
Thanks for your help.

Does the jittering occur only when you are running a particular game. What resolution do you have set in the game itself? My monitor by default is set with a 85 Hz refresh rate and 1152x864resolution, but when I set certain games to the maximum resolution setting within the game my graphic card lowers the refresh rate to one my monitor can handle at this maximum resolution. In some cases the resolution drops to 60Hz and results in a jittering screen.
