Ok, I'm gonna be real with everyone as I came to this conclusion 2 days ago when the shit hit the fan about GHOST running like crap on both systems.
The reason's minus poor tools/ESRAM limits that the xbox looking crappy along with the possibly higher res'd PS4, is because of bad game/Engine optimization.
Let's take a look at this Big turd of unoptimized mess on pc:
Specs according to Steam;
Those are Minimum specs! 6GB of freaking RAM for a old ass engine with modifications?
40GB of HD space for a shooter?
GTS 450, or HD 5870 for GPU? Those can run most demanding games at medium settings, that look 2-3x better than GHOSTS.
Look at previous entry which was actually Optimized correctly:
Black Ops 2:
Steam;
The difference is fucking Staggering isn't it? AND Black Ops 2 ran DX 11, just doesn't say that in Minimum spec page, main page discloses that information.
I am going to call this one more on Activision, than Microsoft, even though we have proof of the down sampled resolutions on most of their games.
Just my explanation, Don't flame me!
If this has already been brought to light, let me know.
You'd have more of a point if we didn't have games like Killer Instinct and Powerstar Golf both published my Microsoft and both at 720p.
