I got a little problem!! When i try the program lesson5.exe (from Lesson 5 of NeHe), i have 0% CPU usage. But when my friend tries to start it on his PC, he got 100% usage! What am i able to do=? Someone got an idea=? Thx HolyHead

It's nothing weird unless it's really blocking his system. His system + driver probably have bad traffic issues.

Unless you have vsync or some frame rate limitation it's perfectly normal to be running at 100%.

i have heard something about making cpu to wait other calculations. the solution was using a wait method in render function.

If I am not wrong for GL this is Finish.

okay, thx guys, nothing to worry about at the moment!!

call glFinish() just after glSwapBuffer()

alterantly you can do the following

if (LASTFPS > 100) wiattime++;
renderall()
sleep(waitTime);
