his tutorials don''t seem to have an fps counter, how are you calculating the framerate?

also, nehe''s tuts don''t disable vsync, so if you''re maxed out at 60FPS or 30FPS or whatever the refresh rate of your monitor is, that''s why.

with disabling vsync i get around several hundred FPS on most of his basic tuts

if you''re using openGL, and your card supports the extension, you can do it with this code using openGL extensions. if you don''t know what openGL extensions are or how to use it look it up


PFNWGLSWAPINTERVALEXTPROC pFunc = NULL;
if ((pFunc = (PFNWGLSWAPINTERVALEXTPROC) wglGetProcAddress("wglSwapIntervalEXT")) != NULL)
pFunc(0);


if you''re not or your card doesn''t you can sometimes do it from your windows desktop properties dialog box. it all depends on your video card driver. all newer cards allow you to disable vsync google it on the web.

if your using an older voodoo card, that''ll be why. They don''t support GL directly, (especially in a window). This was the reason for 3dfx ''quake 3 compatible'' drivers that popped up when the game came out.
