Get outta here DX8
Due to the loss of performance after installing DX8 on many systems, I thought maybe some of you would be looking for a way to exorcise it from your systems. You can't just install a previous version of DirectX over it since the install program will detect a newer version of the program and immediately abort the installation. There are two files I found out there that can get rid of DX8 for you. One is over here
at TweakTown called DX Uninstaller (it's at the bottom of the page) and I can't remember where I found the other one, but it's called DX Buster if you want to find it. I'll post a link if I remember where I got it from.
