If I ever do anything at full rez it sure will. But I dont think its gonna be needed for the final sprites.
Oh and a handy note for those who don't have v14 yet but have a dual core (or quad) system
If you bind master.exe to the second core there's a chance you'll get a hefty performance increase in rendering since windows isnt dualcore supported yet. (XP that is) So by binding it to the core that isnt running the majority of the OS you get more cycles for AM.
I bound AM to the second core and my render times went from 12:20 a frame to 8:30 so almost a 33% increase.
