I don't think it's the hardware's fault, as I tested it on two different computers using the same O.S and they gave the same thing, I'll put Arch Linux XFCE on a pendrive and boot as live-cd to test. I'm suspicious of some system update or kernel update.
Which O.S do you use?
If it's Windows I know the DDU "Display Driver Uninstaller", I've never heard of a program to remove video driver in Linux.
I think the only thing I could do is go back to old driver versions and test them, but it's very annoying to do that. I made the game work via Wine and it's running fine, until I get a video card, I'll play through Wine anyway.
