One thing I've tried that's mostly reduced the horse lag issue is add "Max Memory Usage=64" under the "[Game Options]" section. Apparently by default NWN caches 16 megs of a certain type of data, which includes horse animation data. If you set it to 64, which is the maximum amount, it can help a lot. Note, you'll still get an initial lag spike as it loads the data from your hard drive, but the next time you see a horse it will hopefully be cached so you don't have to reload the data (causing the nasty freeze-up). Here's the first part of my nwnplayer.ini (located in the NWN folder):
Code: Select all
[Game Options]
Max Memory Usage=64

TooltipDelay uSec=100000

Some people report good progress... its helped me somewhat.
