I say that's the last thing you should do.
I'd suggest to update your graphics card's drivers before installing an older version of Toribash.
How to update your graphics card? Well, firstly you should know what actually is your graphics card.
This program might help you in that.
Props to SkulFuk for making that fancy program!
After you know your graphics card you should start seeking for the new drivers for your graphics card.
Type in Google your graphics card with "drivers" in the end.
Take the link that takes you to your graphics card's creator's site to avoid any kind of virus problems....
Download and install the drivers... And that should be it.
If this won't work, then I will move this thread to Support... I bet SkulFuk and/or SlipAnc know something that I don't.
