I'm currently working on NWN2 on my system. You can see my build in my signature. I run it on 1440 * 900 resolution. I don't use anti-alaising and I have shadows and light sources on low setting. Everything else is on the highest settings and I don't have any problems. At least I didn't have a problem until I replaced my SATA drive with a PATA drive temporarily. Then I noticed that it's a little jumpy sometimes, so maybe there is something about the SATA vs PATA drive. Of course, my SATA drive had a 16 MB cache and my PATA only has 8 MB.
