The only place anything runs at processor speed is inside the processor, so at the VERY best only small parts of your program will ever run at that speed.
the program timing is "perfect" this time
That's an interesting comment :lol:
How are you doing the timing?, I've been writing a hardware interfacing program for many years (WinPicProg) - it took me a LONG time to find a Windows API that will give me (mostly) 1mS accuracy.
If you've got an accurate way I'll happily 'steal' it! :lol:
