Wow, I wouldn't be that harsh. What settings are you talking about?
He said with all settings and sliders at max. There are lots of settings in there and cranking them all up in combination, I can't see being easy for even multiple top end GPUs.
I'll actually be a little disappointed if all those settings exist and they don't cripple a couple of top end GPUs even at 1080p. That'd put a dampener on the effect of actually having all these settings available, because the scalability would be limited needlessly at the top end.
Well right. PCSS sounds cool though. Any current games other than GTAV have it?
Far Cry 4 and Assassin's Creed: Unity have PCSS, although I'm not sure on the implementation in FC4, I've heard some mixed things regarding it (due to the various patches) and I haven't checked it out myself in a while.
