wglext - extension not installed on pc

[zecbmo]

I am trying to disable vsync in openGl with WGL_EXT_swap_control using wglSwapIntervalEXT(int interval).

I am trying to include the wglext header but after much searching it seems it is not installed on my pc (using opengl extension viewer to find this). I have tried installing the windows sdk and updating the .net framework but still cannot install this extension.

Is there anyway to include this. my graphics card is an nvidia GTX 770m. Or is there a simpler way to disable vsync.

Thanks
