The purpose of vsync is stop flickering (by syncing the gfx card refresh with your screens refresh) so I guess it would make sense that you see flickering when vsync is disabled. OpenGL perfromance probably isn't as good as D3D so doesn't render at framerates that exceed you screens refresh rate, ergo you might not need it enabled with GL, but do with D3D.

Well, when I disable vsync on my other cards it sure doesn't look like that. Sometimes you can see through objects/walls. Maybe someone with a TNT card could give it a try? btw, powerstrip does not disable vsync on the newer drives, only rivatuner worked. I ended up trying some older drives, 5.32 and 8.05 and they were the same.

Yes, seeing through objects and walls doesn't sound like a vsync issue o.0. More a driver issue maybe? Or it could be a combination of driver and/or hardware slightly malfunctioning.

Pausing your video at various points seems to display the same issue you mentioned, some geometry seems to be left out when rendering in alternate frames? there is slight tearing too. Its seems quite screwy with dropped geometry and the refresh is obviously bang out of sync with what it should be. Is double bufferuing enabled? I don't have a TNT set up so can't test anything for you I'm afraid. Is there any reason you want vsync disabled?

I'm sure I've heard of this problem before. Sounds like a buffer problem.

Can you try a much older driver and see if it produces the same results?

These are from 2000 and run even on a GeForce2, so give them a go.

Ok, I got it working normally. I went through all the Nvidia drivers in the vogons driver library and the detonator 2.08 drivers work. I noticed the rivatuner vsync page changed with different drivers. With 2.08:

and with 45.23:

That's interesting, I'm not the only one to have the same problem with newer drivers.

I just wanted vsync disabled so I could benchmark the card and compare the results with other cards.
