i think the advantage comes in that you can keep working with your scene in the foreground while rendering in the background... but unless you are making multiple frames of the same scene this isn't an advantage- i happen to be doing a lot more animation now so this will help me, but i still wish "built on a 64-Bit render engine for incredible speed and quality!" actually translated to performance.

oh and they did not completely stamp out the GL bug, if im not in Sreed initially when i load the program, next time i click NEW document or load up a Cr2 i'll crash...
