O.o

Graal normally doesn't take 100% CPU time.
The problem is that there is only way in windows
to do precise timing, and windows uses the same
thing for measuring the CPU time taking by
a process. So you will always end up using 100%
in the task manager no matter if you only draw text
or some 3D stuff. It is NOT showing the correct
CPU usage like Linux tools do. Some games turn off
the precise timing if they are running in background, then
you see the % dropping.
