if they can do old DOS game RTX stuff, why can't FFXI?
Ah, the old, if someone else can do it why can't you argument.

The original quake has been ported and rewritten etc a bunch of times. It's not going to work on the actual DOS version which can't use modern graphics cards at all. The WinQuake port, possibly if it's still being updated, but again, just because something works for one game doesn't mean it will work for another (without likely extensive modification that they aren't willing or don't have the time to do).
