Earlier iterations of the Forza game series aside does not look like the PC is missing much. I mean Forza 1 & 2 are not going to be missed by many these days. Most games do not have issues then like you said . I'll take what you say about PC stuff with caution, you concede you don't care about or care to understand PC stuff.
To be fair MCC had loads of issues on launch on the Xbox one from what I remember so I can see these issues being ironed out the same way. Every PC game ever released, especially these days have people shouting about the problems on the internet which will make you believe that PC gamers don't play games but just fiddle with files and patches, even console games have issues but there you're at the mercy of the developer to fix. I'm not a fan of tinkering myself so 95% of the time I just click and play .
