Wow it runs really smooth (apart from the FMVs) - Seems I can run it on full graphics settings with my 4 year old rig (3.2 GHz 6 core AMD CPU, Radeon 9870 1GB VRAM, 8GB RAM) as well, and it only taxes it about as much as Team Fortress 2 does, apparently (not much at all).
I spent this afternoon replaying the original AO and N'n'T handles differently of course - Not that it's a bad thing, just gotta get used to it. But it's really nice how you can rebind all the keys to the original ones.
But yeah, I'm pleased as punch, thanks so much, JAW!
