pro tools 11 and mac pro

[lancemcv]

I have an r9 280x in my Mac Pro same laggy issues in Yosemite , in mt lion no issues same version of PT 11.3.1 and 12. Don't run out and buy a new graphics card and expect this issue to be gone. Here are two threads on the issue with a fix which is running Quartz debug, it gets rid of the problem for now, if you have pt 12 call avid and report it, the more we report the better chance they will look into it.

the GT 120 is old and a not powerful so a new graphics card is a good idea anyway.
