Mostly correct.

There are some games (more and more) that have native support of Sony controllers, even giving the correct prompts, but other games will need an input wrapper such as DS4Windows or Steam Input (built into Steam, have to run non-Steam games through Steam).

I really like Sony controllers, but their lack of PC support is quite the hindrance. If Sony fixed that with their newfound interest in PC they could have a great PC controller option.

One of the things that pisses me off about it is they *do* have automatic, native support, they force you to use the touchpad as Select and disable the Share button.
