The two games, NWN1 and NWN2, use different game engines. According to the CD Project Red references, Witcher uses the NWN1 engine, so I would be cautious about extrapolation from NWN2 over to Witcher. Test it out before publishing it. In the case at hand, the various onboard chips do not have either the power or the speed to run games of this caliber in at all a proper manner, not NWN2 nor Witcher. The fact that the game's launcher (in the case of NWN2 at least) detects the lack of 128 MBs of actual VRAM is a boon to them. They won't enjoy the game anyway.While I was still active there on that forum, there were some laptop owners (no laptops are supported for NWN2) with real video cards, just low power ones, with only 64 MBs of actual VRAM, also involved in the threads about laptops. But they also had low quality video processors (else they wouldn't have been Hypermemory/ Turbocache devices).
