So it's interesting to see the real start of PS4/Xbone quality gaming on PC and what kind of specs you need to run these games.
AC: Unity
Far Cry 4
Dragon Age: I
All can't run 60fps/1080p max settings on the strongest single card on the market $600+ GPU (GTX 980) /$1,500+ build with no AA. They hit close to 60fps most of the time but all 3 are showing dips into the 45-60fps range. If you want good image quality (aka, some MSAA 2x or even 4x) you're looking at around 30-40fps and you need to SLI a second card ($1,200 worth of GPU) for 1080p/60fps 4x AA which is kind of insane requirements. And that's with the strongest card on the market, with anything near what's actually in the PS4/Xbone you probably could get the games to even run.
Now the question is whether the new engines are just so high tech, that PC is getting dated very quickly, or if the above games were just rushed & un-optimized for PC. Then the question is whether this is just going to get worse or better as the generation gets along. Hmmm.
Otoh,
Alien Isolation
Shadows of Mordor
Run amazingly well and optimized on PCs. So the jury is still out.
Next up is GTAV which could go either way since it's a big impressive world with a lot going on, plus GTAIV being terribly unoptimized on PCs, but if PS4/Xbone are running it pretty much 1080p/30fps locked maybe the PC version will be able to handle it nicely.
