bjymoon: I'm having some problems like characters sometimes lagging and teleporting to seconds after and before (solved the movement sttuter which was separate). In-game battle animations not firing or firing late, and characters models popping in and out. Enemies that were not stealthed often appear out of nowhere.

I used to run it in a much less powerful machine back before GOG, and I didn't have any of this issues; not to mention the AI seems stupider than before running around like headless chickens.

I tried looking up some solutions, like the client extension, restarting computer to reset up time, but came up empty up to now in terms of actually solving my problem. I don't have any mods or community content installed right now except when I tried the client thingy. Does anybody have experience with this type of problem? Any help would be much appreciated :(

Engerek01: Which game?

There are similar issues with both games because of the new video cards. I cant help you myself but it will be easier for people to help you if you tell which game it is. NWN or NWN2?

LordGarrius: CE helps quite a bit with the camera issue and 'warping' issue....but doesn't resolve it completely. It definitely is better than the vanilla version but it doesn't completely fix it, from my experience.

Also you can find an Tony K's AI mod at the Neverwinter Vault, can't post links here.
