Get high speed , low latency ram at least 32 GB. Have a higher initial load time and keep more of the game in ram. Also have good amount of ram in gpu.
Yeah but change the subject as you cannot get a solution SSD/IO with that level now you have to use big amount of ram, regarding the vram yeah is good but the amount is even
less in a 2080 ti than the PS5 (16 GB less what 2.5 or 2).Aside the issues they need to manage like mapping and coherency in the gpu cache (which I am sure the new gen of GPUs will improve)
and cache for the same memory directions of the gpu cache.
I am sure Epic games will use a big quantity of ram in order to close the delta but that also is another approach and even then you said a SSD raid which probably will cost more than
all the PS5 to get a decent size. PCs will exceed the PS5 sure that will happens just now doesn't do it in those aspects.
Finally the use of a super fast SSD cost CPU power .... like a lot that is why the consoles use coprocessors in the IO.
But yeah a PC which left around 7 cores available to only the game after of use a fast SSD like what do you want 12 cores, with enough vram and power which now
you get in a 2080 TI (more power less vram), with 32 GB of ram and RAID 0 of SSDs ..... yeah that sounds like a normal high end PC.
