Runnig my GL program, I found strange slowness with drawing scene at 9600gt.
I think this is my fault, but not.

Default fasm OpenGl demo slow too!
Other cards (ATI,Intel) - fast.
On regular video cards speed is correlated with scene complexity and window size.
On 9600 time of scene drawing is constant! - and very slow.

I think there is some functions of OpenGl regulating that...
Anybody knows the solvation?

Are you using nVidia drivers or the ones provided via WindowsUpdate? I remember using WindowsUpdate one once with GeForce FX 5200 (or maybe my recently replaced GeForce 6600?), and also had a terrible OpenGL performance (seemed to be not hardware accelerated at all). Solved by downloading drivers from nVidia site.

This shows frames per second, please try...

Also the FASM demo refreshes at 10ms which is purposely slow.

The glFONT you recommended shows 61-60fps for both myfont & wglfont.
Display freq = 60Hz.

*VSync on* was..

Thanks.

To on/off vsync:

.data
StrGlVSync db 'wglSwapIntervalEXT',0
wglSwapInterval dd 0

.code
invoke wglGetProcAddress,StrGlVSync
mov [wglSwapInterval],eax
stdcall [wglSwapInterval],0 ;1 for ON, 0 for off
