Strange Display Warping

[CodeBunny]

I've noticed that when I'm displaying a "moving" scene, I get a strange warping on the display in horizontal bands that slowly move up or down the screen. From what I've seen on the forum, this sounds like it's related to V-Sync, but I set V-Sync to on when I initialize the program.

What's causing this/how can I avoid this problem?

Check to make sure you aren't forcing V-sync off in the driver.

Otherwise, if you are using an LCD display, there may be nothing you can do about it. Some LCD panels have too slow of a response time to show a moving image at the frame rate the graphics card is sending (like 60fps needs < 16ms).

Yeah, I checked the driver settings, and they were good. I actually tried setting the driver to force V-Sync in applications, and it looked exactly the same.

I just tried running at a lower fps and didn't see the problem, so you're probably right.
