Will this run Quake 4?

[DoomUK]

For a final note, the Quake 4 Graphics engine is alot different then counter strike source, and doom3.

You are aware that Quake 4 uses the Doom 3 engine. That means, it will internally use the same renderer(s) and interpreter (everything you 'see' and everything you 'don't see' respectively). So on paper, it will theoretically require the same hardware specs as the original Doom 3 engine-based game, Doom 3 itself, much like Half-Life 1 could of had the same requirements as Quake 1 - but as we know, as it was a massively tweaked version of the Quake engine, the requirements went up.

DoomUK is right.

I also don't think Raven modded the Doom 3 engine for Quake 4 but I'm not sure.
