Ok, if you're wondering, i'm playing Sonic Mania at full 60 FPS, fullscreen, no hiccups, nothing, no input lag, nothing, no crashes, everything is fine until now (i'm in Mirage Sallon). Well, i'm not a expert in computers, but i know a software (specially a video game) is programed to work in different builds, old and new, bad and good ones, but the developers can't predict which part everyone PC is using, what drivers they are using, what O.S, what is the state of the PC used, this could cause some oddities, i've seen weaker PCs running better games than mine couldn't handle, and my PC running game it shouldn't, like Sonic Generations. In many brazilian Sonic fan pages and groups, PC users reported the same problems. Many people assumed this was caused by Denuvo, taking much of the system's resourses to run the game, but is that all the cause? I find it all strange because i never had any performance issues with this game on my machine, even before the update, and its a 10 years old PC! Since the release day, i heard and read from many PC users that Sonic Mania was running with low FPS or some hiccups even in High End machines.
