Dang itttttttttttt. I really want to get rid of that animation, its way too slow.
Megazoomer+SIMBL is faster/smoother and works with 10.7 too!
After clean-install of 10.7 and reinstall of SIMBL it works well.

I've found the command that disables the new window animation, which was my main gripe:

Try "iTweaX". You can get it at Macupdate.com. It has options to disable all the extra animations and whatnot.
Here's the link to it:
