This game is a complete mess. And all the patches in this world cant fix it.
Fun fact: A friend of mine is a Gothic nerd as much as I am a Zelda nerd. So he installed Gotich 3 and the addon with all patches. Now get this: Highes graphic settings available, game sruns with stable FPS and the occassional lag. So i figure, to make it work ebtter reduce graphcis quality a little.
Guess what: The game is slow and choppy as heck. so basically, with the ebst graphicsl settings, the game rusn smoother than with reduced quality.

ATI card of course. I think thats fun as hell XD
