Jason Keeney: I dont really know a thing about the 8500... what its capabilities are, if its dx9 compatible, etc, etc... But I do know that Doom 3 uses OpenGL for its graphics, and therefore, while the 8500 may not be Dx9 compatible (from a Direct3D point of view), it *may* be OpenGL 1.3 compatible and perfectly happy to run Doom 3.
However in our case we are acutally using the Direct3D component of DX9 and I'd have to say that the chances of getting NWN2 to run on non-DX9 compliant video card pretty much zero.
[Update Mar 2005] Feargus Urquhart: Some of the stuff is still up in the air, but we are pretty sure that it's going to be a 128MB video card.
[Update Oct 2005] Brian D. Lawson: To answer both questions here at once (unofficially of course):
1) The minimum estitamed memory to get the full eye candy will likely be 256 meg. However, that's going to require a rather potent chipset as well (i.e. 7800/R520 type of chip).
2) The minimum estimated spec to run the game outright will likely be a 128 meg shader model 2.0 card. But as we all know, there are plenty of those out there in the NVidia FX5xxx series of cards (mainly 128 meg versions) that are miserably slow in terms of their shader performance.
If you happen to have one of those and still want to play with decent performance, you can always run with the vertex lighting option turned on.
