I'm still having the fps drop problem with the .132 update. It used to work fine (60 fps on ultra) until I got to the first town, then it drop to 50-40-20 fps... quicksave fix it for a time but not long.
Definitely a strange sort of problem...I haven't experienced it with any version of the game so far (now .132). Also, I'm running higher res textures (mod) for almost everything in the game. I have, however, turned off texture streaming. All in-game settings maxed, save for bloom, motion blur, & DoF, which I turn off as I generally don't like those effects in most games. Post processing I run FXAA as I found I preferred it to SMAA x1. Single-player only.
