How can i disable VSync in a program that is using OpenGL ? I think swapbuffers or endscene does wait for it but i want to disable it. I can do this in any way ? moromete PS. I would love to search for an older post about this subject but the search system kindly replyed : The system is not functioning

There was a example on this at www.steinsoft.ner but it seems to be removed.

Here is a code that disables vsync from the steinsoft site:

include  //for wglGetProcAddress(..)#include <GL\gl.h> //for glGetString(..)#include <string.h> //for strstr(..)//function pointer typdefstypedef void (APIENTRY *PFNWGLEXTSWAPCONTROLPROC) (int);typedef int (*PFNWGLEXTGETSWAPINTERVALPROC) (void);//declare functionsPFNWGLEXTSWAPCONTROLPROC wglSwapIntervalEXT = NULL;PFNWGLEXTGETSWAPINTERVALPROC wglGetSwapIntervalEXT = NULL;//init VSync funcvoid InitVSync(){  //get extensions of graphics card  char* extensions = (char*)glGetString(GL_EXTENSIONS);    //is WGL_EXT_swap_control in the string? VSync switch possible?  if (strstr(extensions,"WGL_EXT_swap_control"))  {    //get address''s of both functions and save them     wglSwapIntervalEXT = (PFNWGLEXTSWAPCONTROLPROC)      wglGetProcAddress("wglSwapIntervalEXT");    wglGetSwapIntervalEXT = (PFNWGLEXTGETSWAPINTERVALPROC)      wglGetProcAddress("wglGetSwapIntervalEXT");  }} bool VSyncEnabled(){  //if interval is positif, it is not 0 so enabled   return (wglGetSwapIntervalEXT() > 0);}void SetVSyncState(bool enable){  if (enable)    wglSwapIntervalEXT(1); //set interval to 1 -> enable  else    wglSwapIntervalEXT(0); //disable}

You can simply use this three functions.
At first call InitVSync() and then the another funcs.

Thank you very much for your answer.
I will try it right now as soon as i understand what it does
