I hate QT! I deeply believe all the problems that I have started encountering since switching to Maya 2012 are all related to QT. The most annoying of which is the damn screen no longer refreshing. It's completely random too. I can model for two minutes or 20 hours before the screen stops refreshing and the channel box and outlining are blank, forcing me to restart Maya! There is no excuse for this! I use Modo, Max, Blender, Inventor, Alias and none of them have any problems with my graphics card! Maya 2009 and lower run fine on my system. From the time they switched to QT it has just been a nightmare and I am not buying a $6000 graphics card just to use Maya! I'll use a freaking crayon and paper first!
