PS5 has 16GB so that's hardly surprising.

The PS5 has shared RAM between CPU and GPU. Not sure what the average split between the two is in games, but it would certainly be wrong to say it has use of the full 16gb like desktop cards have.

It's mostly going to be graphical assets. Especially in a game like this which doesn't have much else going on, and is constrained in terms of what else it can do because the base game ran on PS4.

Even on PC most of your RAM is just being used as extra cache for graphical assets. Very wasteful tbh, but it is what it is.

I'd guess VRAM at 75% of console RAM to be a safer bet. So 6GB last gen, 12GB this gen. Maybe more if you're pushing higher resolutions, but most PC gamers aren't even at 4K, let alone going beyond it.

Is it actually that little that gets used by the CPU? I assume there'd also be some overhead that gets claimed by the OS and not the game. Maybe 1-3gb?

[–] [email protected] 2 points 7 months ago

Looking it up, the OS takes 3.5GB, leaving 12.5GB for the game.

But most games also run a little less than native 4K unless you like the 30fps mode.

The 8GB GPUs are looking increasingly stingy at this point.
