"Do you support any special display modes? BioShock 2 has been designed from the outset to take advantage of NVIDIA’s GeForce 3D Vision displays. Users with compatible display units and peripherals can experience the world of Rapture in full, breathtaking 3D."
this makes me very happy. I sure know what platform I'll be playing this game on now. :)
This joins Batman Arkham Asylum and Resident Evil 5 as games on PC that have native built in 3D vision support. Basically they are 3D vision certified and work with it 100%... There are about 400 other games available that work excellent as well.
So if 3D is your thing, there is no reason to wait for consoles to get off their ass and deliver an online downloadable game in 3D...Current gen gaming in 3D is in full swing on PC.
