Recently "The Witcher 3" sold 4M copies in a short amount of time whereas 1.3M are attributed to PC sales [1].
Even Indie games like Cities: Skylines which is PC/Mac only recently sold more than 1M copies in a short amount of time. [2]
I don't really play much but i follow PC Gaming and it has been on the rise for years. Free to play MOBA games like League of Legends have over 8M concurrent players in peak hours with 27M people playing at least game per day. That is more than the viewership of even the most popular TV series, every day of the week.
However, it's _nothing_ compared to the installed base of PCs. That's probably on the order of 2 billion. Most people don't use their computers to play AAA games, and likely not games at all (Steam only has 125m active users, say).
