I raised mine to 1024 and I've not had a single graphics bug, or crash.
DLPB, i installed R02 the day it came out, to update to R03b should i install it over clean lgp files? i don't mind restoring the kernel, or the exe, but my battle, magic, world, and high_us lgps are modded and i don't want to have to do it all over again haha
