what happend to the frame rate?

the game is going very slowly for some reason. this seems to be a bg1 problem as bg2 runs like it normally does with out any lag. it seems the patch may have done something to the graphics settins as it says i have direct x 9 whitch is not true i have 11 and bg2 says what it should say with open gl 3.0.

Or do you have the impression the rendering is stuttering, dropping frames, slow down significantly under 30fps? then it would be a renderer / driver problem that may solve with a graphics cards driver update or fiddling with the settings like described above.
