For those of us who bought PS4 Pro's, boost mode is exactly what I've been hoping for. Impressions online have been pretty positive so far and digital foundry just put up an initial analysis and the improvements can be pretty dramatic. So far, up to a 38% increase in performance. While this doesn't sound like a lot to some of you, it can push games to a consistent 30 or 60 frames!
Now with this feature, it's not much easier to recommend people purchase the Pro instead of the base.
Not sure if anyone is in the beta, but if so, any impressions?
