I played through the single player of NWN 2 on Athlon XP 2400+, 1 Gb RAM, Radeon 9700 (128Mb). The game ran quite smoothly in many areas at 1024x768 resolution, maximum graphics quality, no AA/AF, no shadows on that system.
By smoothly you mean 5 fps? I doubt you could select every graphics option maxed out (especially lighting).
I am using E6600, 2 GB RAM, EVGA 7950 GT KO SC and happy to be around 25 fps with medium settings and 2xAA. NWN2 treats all ATI cards pretty poorly if you look at the NWN2 forum vid card optimum settings.
well so far from reading all the posts its still 50-50 chance of being able to run it. For some reason the new pc's have more trouble running it than the old pc's? Core 2 duos being eaten alive while good ol' P4 and Amd 64(2400-3400) run it ok. This is one of the strangest games out there since you are truly gambling with the ability of being able to run it or not.
