Like I said, it’s a little rough back and playing older Yakuza games in 2021 and not just because of the more rigid animation and lack of first-person perspective. PC versions of Yakuzas 3, 4 & 5 they also have (or have had) some technical hiccups.
A few weeks ago, Modder Silent – which I covered a few years ago doing pretty much the same thing for Yakuza 0– has released its own patch for Yakuzas 3 & 4, which solves things like excessively high CPU usage and crashes that happen when you end a fight with a heat move (the ideal way to end a fight!).
Sega then released its own official patch that did … mostly the same things! However fixed, it was time to take a look Yakuza 5, where he managed to solve problems such as, once again, overuse of the processor, problems with dynamic resolution and a strange error if anyone with non-ASCII characters on their behalf would get an accident if they used photo booths of the game.
Sega may come later and fix the ones with an official update, but if not, or if you want to fix them now, you can download the unofficial Silent patch Here.
