As I started to write an opengl-game-engine, I would like to know how to switch the buffers without waiting for the vertical sync. Maybe I have to make use of a third framebuffer, eventually an auxiliary buffer, but is there a possibility like the flip-instruction under Direct3D to switch these buffers without regarding the vertical sync. This isn´t a major problem yet as I have still some other things to do, but I search the web from time to time to find a hint for this problem and I didn´t find any help. Seems to me, that disabling the vsync was never of interest to the developers of opengl... Thx

There is no flip control in opengl, but there exist a extension. I dont remember its name right now...
ill post it when i come home.

its called WGL_EXT_swap_control

Thank you very much. As you mentioned it as an extention, I found a pdf-document from nvidia, which explained the most common extentions. I found the extention and built it in. And it works !

Could you post that url, on thos pdf documents? Triple-Buffering was something I liked a lot when I was programming DirectDraw programs..

No problem, the url is:

But remember, the solution is not triple-buffering, it´s just to switch off the vertical sync.
