Hey all,  
I am testing a swf on my MAC Intel 2.6ghz duo-core with Firefox and am averaging 20 - 25 FPS. When i test the same swf on Firefox via VMware running Windows XP it is averaging 10 - 15 FPS. Does anyone know if it’s VMWare that’s causing the slowdown or is it Firefox on Windows that could be the problem?  
Thanks.
