To be honest, i didn't played on PS5 with the comparison in mind. Just because the noise from the PRO is like a airplane while i run that game, so i could've support it any more. Before, i didn't took too much attention but now that i own a PS5... But i won't lie and say "yes it's smoother". Needs some retry. But the noise when there's too much "actions" or details on the screen start sometimes to increase that much, you're fearing to say RIP to your console.
It's not the case with many others games but PES 2021 makes suffering even a PRO and in 1080p not 4K, so i can't imagine on a classic version or PRO + 4K.
I wouldn't be surprised if the PS after some game would be transformed in a washing machine.
