Hello all,<br>
<br>
I didn't had time to make heavy testing.<br>
But I tried some things today and it seems finally I manage to go
further than 50% of the GPU.<br>
You can see the evolution of my graph here if you want:<br>

It is with different testing : changing resolution / frame / options<br>
Auto-hiding the dock doesn't seems to change a thing, and sending
fullscreen before creating the window did not significantly change
the GPU usage.<br>
I'll try to do some more professional testing with Cyrille tomorrow.<br>
What is the best way to test the GPU usage, drawing numerous
squares?<br>
There is also many different parameters to monitor and i can display
some others if you prefer.<br>
The tool i am using is a developper tool from apple : OpenGl Driver
Monitor<br>

having to share time with the rest of the GUI, but in full screen
there is nothing else taking time.<br>

<br>
from my experience, Gem is 2 times faster on the same computer
using ubuntu than osX.<br>
thanks to nvidia profiling tools, Nicolas pointed that gem is
limited to 50% usage of the GPU.<br>
there is certainly a limitation somewhere on osX preventing
application to use full performance of the hardware.<br>
<br>
so, you applications are slower, but the interface will always
be smooth...<br>
