So... What Exactly ARE the PS3 Limitations

[Kosmos992k]

Yeah it's not much of an issue PS4 Pro belongs to PS4 generation I guess Scorpio will be the same. The game will run as it is on Pro but from what I saw companies will push patches to allow better framerate and resolution in order to get the extra candy from Pro. So it the future there will be small patches to tweak the PS4 Pro version.

They'll only have to push out a patch if their game locks framerates at 30fps@1080. If a game has a dynamic framerate, then there should be no need for a patch in order for the game to run at a higher framerate, and if any quality tweaks are made for games running at 1080 resolutions on the PS4Pro, we might see enhanced anti-aliasing regardless of what the game does - for example - without a patch.

Dont know if its been said, but its actually 256mb. (360 had 512mb)

PS3 : 256MB system + 256MB Graphics. RSX has full speed access to both pools, CellBE has full speed access to system memory and a limited bandwidth bus to write to the graphics memory. Total memory = 512MB but it's hard partitioned meaning devs always know what they are working with.

Xbox 360 512MB unified memory (one pool) split between graphics memory and system memory. the partition between the two pools within the 512MB block is variable meaning that Devs do have control over memory allocation to the GPU, but there are no guarantees about the size of the memory available - it depends on the behavior of game and graphics code at run time. Practically speaking, the 512MB of memory in the 360 splits in roughly the same proportion as the 50/50 split on PS3, it's just not a hard split.

Both of those older consoles are memory limited and use overlays to run code larger than the physical memory available.
