Problem: Suddenly today, on logging into PotM or any other NwN server, offline or online, the game speed has fallen to 1/3 of its normal speed. My framerate is just fine, about 200 fps, but my character moves and animates very slowly in the OOC area.
Elaboration: The character carries 115 out of 156 or so lbs of items, so I am quite sure this is a technical issue since it also happens if I load up another character in a singleplayer Pretty Good Character module. Game speed was just fine the day before, and I do not remember altering NwN or graphics settings inbetween. So has anyone else encountered something similar?
Suggestion: I've tried setting Client CPU Affinity=2 in nwnplayer.ini (to force nwmain.exe onto only core 3 of my four CPU cores) instead of the default -1 or -2, and I tried removing OpenGL32.dll (from the GLIntercept workaround for GeForce 500 series cards such as mine). I've updated Nvidia graphics drivers to version 331.82 and hopefully this is enough and will fix the issue after I try again tomorrow. If not I will try forcing Threaded Optimization off for nwmain.exe and nwn.exe in the Nvidia control panel.
Conclusion: Of course I should have tried restarting/updating graphics drivers first; I doubt it changes anything but keep my fingers crossed and leave this post for anyone who might experience the same problem of good fps but slow game speed. The issue must be related to multicore rendering or processing, but what the exact solution is I don't know just yet. Feel free to chime in if you have other suggestions to try for people in this situation.
