Fixed it! (For the XP version). Just needed to turn off VirtualBox's mouse integration so I could turn down my mouse's DPI inside VirtualBox. This makes the mouse move extremely slow outside of game but at the moment I'll only need to use that virtual machine for DTR2 so that really isn't a problem. Really don't know why I didn't think of that before but it's great to be back. Thanks everyone!

go to the NVidia website and see if they can give you any help.
