now i have a TIMER to "switch" Core of CPU.
use any parameter to enable it

Code: Select all

   MCPU.EXE XXX -> will start TIMER

this will show same Graphic to paint 1000 Lines but use < 25 % CPU
so i try to use mt=no but that make no Difference with this Demo

so what is using so much CPU ... "just" Paint some Graphic ...

Tip : start Taskmanager before run Demo and move it to right Side and watch CPU %
