Ill be getting a capture card soon and ive been thinking of doing runs on my playstation instead of my laptop once I do, my laptop isnt always the best. there is a category for ps4 but what about ps5? Would I be allowed to do runs on ps5 and mark it as ps4 or put in the description it was on ps5?

Also im kinda worried it might be faster on next gen so should I just run on pc or ps4 instead?

iirc speedrun.com has a console option for ps5 backwards compatibility, if the distinction between ps4 and ps5bc is important, then the mods could add that.

keyboard is generally better for ut/dr, so if you do run on ps5, try to attach a keyboard

it shouldn't be faster at all
