one should not forget DXGI cannot allocate all available VRAM to games on PCBesides Uncharted and TLOU Part I, most Sony ports run very well these days. Hell, Returnal runs at PS5 equivalent settings and frame rate on something like an RTX 3060.
The one thing to watch out for is VRAM. The PS5 has more VRAM than most cards that it's comparable to and first-party devs will use that amount. 8GB GPUs need not apply. Even 10GB might not be enough. Usually, you need 11-12GB which is what I assume the PS5 uses.
you will usually get a portion of what you have in total. if you have a 10 GB GPU, driver most likely will allocate 9 GB of VRAM, 8 GB card will see 7.2 GB allocation and so on. This is without taking background applications that may use VRAM in account (Windows itself will use some amount of VRAM, Steam uses VRAM, Discord/Spotify etc. uses VRAM but they're extra software so I won't delve much into there)
more sound explanation by Kal (special k developer)
people often gets into this false sense of security where they think they match xbox series x's 10 gb gpu budget with a 10 gb gpu on PC or that 12 GB giving them some "headroom". things will get real messy when these budgets are really stressed down the road. more so with DLSS 3 though, as it uses extra amount of VRAM that developers won't tune their game for
