with the release of Ulduar, I've come to realize my comp can't support the game properly and it's affecting my game play. my question is, what is the easiest-on-CPU model that I can replace every other race with (aside from my own of course)? even better, is it possible to make them invisible altogether? another thing would be player spell graphics--would it be possible to replace all the spells with no animation at all? thanks (I have basic knowledge about model swapping/DBC editing from the guides posted here, and I can do both efficiently)
