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

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.

Bye
