Hi folks, Many people discuss about timers and which one is the best to use in your 3D apps for frame rate counting and such. Wandering the web I''ve found this link: http://developer.nvidia.com/object/timer_function_performance.html It is an article in NVidia''s site and has a nice little app that tests all timer function on your machine and tells which one is the fastest. In my WinXP I saw that timeGetTime is the fastest one, many people said it was queryPerformanceCounter. Read the article, use the program and then lets discuss it (again)! Cheers,
