If your current video card was able to play (not just install) Quern, Xing,
and Obduction (I assume you mean "Obduction" and not "Oblation") with the same drivers it has now, then the card should be fine. If the drivers have been "updated" since playing those games, then there may be a problem with the newer drivers, and you may want to check to see if those other games still work.
Another possibility is if your antivirus is blocking the game. What antivirus do you use?
