I currently develop an editor which also does realtime-rendering. Currently I use SetTimer(...) and OnTimer(...) to render in realtime. But I only get max. 100 frames. Is there a faster timer which I can integrate into my MFC construct which perhaps also calls OnTimer(...)? Gero Gerber

timeGetTime, which is accurate up to 1 ms, or QueryPerformanceTimer which is slower but better.

Edit: this is probably not what you're looking for. You need a to override OnIdle in CMyApp and call your OnTimer function from there, which will give you 'realtime' performance.

What about GetTickCount()? isn''t that the same thing as timeGetTime() ?

No, its resolution varies (based on what I''ve heard/tested) between 10 ms and 50 ms or so.

Some of the NeHe tutorials contain a QueryPerformanceCounter implementation.

If you''re making an MFC app, and you want a well-behaved renderer, render in a seperate thread from the application thread. It won''t stall when the user clicks a menu item for instance.
