Anyway, is it worth it to have these huge engines for just a little bit more realism? I mean, look at the Source engine. It runs well even on budget cards today, like the 9800 Pro/XT or 6600's. I've never played F.E.A.R., but I doubt it looks much more realistic than HL2, and you need a rig that costs three times as much as mine to play F.E.A.R. at comparable settings.
