YES. PLEASE use that time to optimize.
Hopefully Last of Us Part II shares enough of a code base with the PC version of the Part I remaster.
Good question. Having not played the PC port myself, I only know that it was addressed by the studio (and/or publisher?), and that people stopped talking about it after a couple months. I personally concluded that the game must’ve been fixed to some degree.
Looks like they updated it but it requires a really fancy PC to play according to a steam discussion I found https://steamcommunity.com/app/1888930/discussions/0/6678353284412255093/#c6678353521951255667
Looks like it runs at 30fps on steam deck also https://www.protondb.com/app/1888930?device=steamDeck
