GEM is synced to the VBL of the display which is 60Hz.  I can&#39;t remember if I put a VBL sync disable message in the gemwin code or not.<br><br><div class="gmail_quote">On Mon, Nov 21, 2011 at 1:53 PM, Jack <span dir="ltr">&lt;<a href="mailto:jack@rybn.org">jack@rybn.org</a>&gt;</span> wrote:<br>

<br>
I am working on an installation on MacOsX.6.7 with Pd-extended 0.42.5 and Gem 0.92.3 (compiled Sep 22 2010).<br>
The graphic card is a ATI Radeon HD 5770.<br>
On this environment, i can&#39;t get a stable frame rate. With [gemwin 50], i get sometimes with the abstraction [realFPS] : 60 fps (strange no ?) then 5 seconds after 40 fps. Even when the scene is the same.<br>
How can i obtain 60 fps when it is write [gemhead 50] ?<br>
Someone has a similar problem ?<br>
How can I fix it ?<br>
Thanx.<br>
++<br>
<br>
