Larian Studios Forums General Chat RPG Chat NWN - I need your help ...again

I don't know the answer, but I can tell you that I run it on my system without any problems. These are my stats:
ME
AMD 1.2 GHz
Nvidia GeForce 2 mx 400 (64 MB)
12.9 GB space left on hard drive
256 MB RAM
Windows is managing virtual memory settings
Creative Labs Sound blaster Live Value sound card
high color 16 bit

I don't have the expansion installed.
I also run it on my notebook which has
xp
ati radeon 9000 mobile
2.0 GHz
512 MB RAM

I tried running it on my old desktop, but got very choppy performance. That was W98
6000MHz
32 MB video card
256 MB RAM

Check the Readme file. Maybe there is an answer in there. Try the official website too.
