The specs were in my first post. It is no entry level machine (Doom 3 it's advertised to run on 1.5GHz P4 with 64mb GF4 cards). Sorry about the typo: I meant high quality; as I said no specular. We tried a few options to see how they impacted quality/performance. Without specular it runs quite faster with little impact on quality. Disabling bumps is quite a different story, though.
I'll eventually play it again for a little longer in the next weekend but the first impression (again, I'm talking about the engine and the engine only) is still a sense of disappointment.
