Re: Enabling Multithreaded GL - any purpose with predominantly Quartz Composer driven code?



So in short, if I have a multi core machine on 10.5.x, does enabling multithreaded opengl make any sense if I start to push my application by loading lots of effects?


I don't know of any appropriate cases where this would help performance, but I've seen a few instances where it adversely affected performance in a negative way (i.e. 60fps compositions dropping to 20fps or worse). As with all optimization, be sure to profile exhaustively to make sure what you're doing actually helps rather than hinders.

Here's a quick doc I found that may help guide you: http://developer.apple.com/technotes/tn2006/tn2085.html#TNTAG7

When/If you find where this option helps, please let me know; I'm curious about where it's appropriate as well (in more concrete ways than the doc outlines) :)
