Choppy Graphics

When ever I play games the graphics seem choppy, not smooth... I am running at 60-70fps but is seams as if the immage is almost breaking when I pan the cammera in all the games I play... Any hints on what I can do to help (ATI Radion HIS 4890, i5 2.6 quad, 4gb 2100hz Kingston ram, Asus P7P55D Delux) I have tried V-Sync but all that does is limit FPS to 60fps (which would be good if I had highly varying fps, but I dont think I do)
 
you still get the horizontal lines when using v-sync? do you have the latest drivers? try going into ccc and enabling vsync on unless specified and see if that helps.
 
no i don't think it would be the psu. usually you get those lines from the game running frames at a different rate than the monitor. try doing the things i recommended. if they don't work, you might just be stuck. you could also try increasing all of the settings so that you get slightly below 60 fps.

An underpowered GPU can result in those symptoms. The 4890 requires a lot of power. The most important part of the system we are yet to know - the psu.
 
I am not a huge gamer but this sounds fairly normal from what I see. For example with Crysis, the less movement I have makes things smoother but fast panning stresses the system. Or need for speed shift, some heavy courses will slow my system down to 40fps under heavy turns in a few tracks while I can get 600pfs on others.

Basically I think panning or fast movement causes more stress on the system and you will see the minimum FPS show up.
 
This is not low FPS. Even in your system FPS is never an issue, as 40FPS is above what the human eye can readily detect anyway. That is why 25FPS is minimum, however anything much over 30 - 40 is a waste of time. In fact many monitors will lock the 60FPS regardless making synthetic benchmark scores meaningless.

The issue here is video tearing which, if not fixed by v-sync, then is very much likely to be an underpower 12V rail feeding unstable voltages to the GPU, which can cause all types of graphical annomalies. This is also plausible due to the high powered GPU installed.

The FPS comment was irrelevant as in no way is this linked, particularly if he is getting 60 - 70 FPS.

It is very unlikely that with v-sync enabled that tearing would continue, so I would suggest we find out what PSU the OP has.

Essentially a well set up system shouldn't show any tearing so if the vsync solution fails, time to look at power.

TO THE OP

What PSU do you have?

What version of Windows are you running? (32bit / 64 bit)
