Should texture compression be on or off?

And Asynchronous delivery should be off right because that makes the packets get sent slower than the control user, which causes delay and lag?

PS: these are for graphic card settings.

try running game booster in the background as well: http://www.iobit.com/gamebooster.html

Yes, Game Booster is really good!
The new Game Booster 3 is free I think.

I honestly thought gamebooster sucked and wouldn't even entertain installing it until I saw a friend go from 10fps to 50+. It works fine, I still don't run it though.

I can't update my graphics drivers on my laptop due to Sony not being compatible with the Nvidia updater, though they insist on using their graphics cards. >.>

Just installed Gamebooster 3 as everyone's always yelling at me to do it! I hope it helps out. xD
