Forcing triplebuffering?

[Gonad the Barbarian]

Is there way to do this on Nvidia cards? Or for Quake3 engine games?

Download Rivatuner. In the PowerUser tab, under OpenGL is the EnableTripleBuffer option - enable it.

I'm not seeing anything for OpenGL under the power user tab.

Excuse my ignorance but what does triplebuffering do?

I don't know all the technicals, but it is supposed to help increase framerate when vsync is enabled.

Ah, found it, had to click on the 'open matched detonator database' at the bottom.

Hot damn, it seems to be working. My FPS aren't plateauing like they were before, smooth framerates without god-awful tearing from having vsync disabled. Thanks Jeff7.

It allocates a third framebuffer to which the video card writes to when the front and back buffers are full.

It can help when using vsync although it certainly won't cure all of the problems that enabling vsync causes. Also the extra VRAM required for it reduces the card's effectiveness at higher resolutions and when using FSAA.
