If its true, but about the wrong demo, then... well, thats not true.

 

As far as RAM goes, the GTX 680 is a 2gb card. Now why wouldn't the PS4 version look better then the 680 PC version?

Hint; it has to do with fillrate and pixel shader rate. IE 8gb of ram is removing 1 bottleneck from the system, but other bottlenecks still remain.

 

You forget the main PC RAM used in the Demo... PS4 4GB (now 8GB) is for CPU and GPU... the Demo runs with a GTX 680 with 2GB + CPU with XGB... this demo needs more than 4GB of RAM I guess.

That's what the guy in Beyond3D said... seems like the Demo was changed to remove some tech that use a big amont of RAM.


And the GPUs VRAM is the only thing being used to draw what you see on screen. Thats it, 2gb for all those textures, lights, particles, ect.

The main RAM in a computer is used by the CPU, and only the CPU. To give you some point of reference, crysis 2 uses about 800mb of system ram., ie what the CPU is using.
