This is what many have been waiting for: cold, hard numbers. Firmware 4.50's PS4 Pro 'Boost Mode' was uncovered by beta testers last week, with users claiming that it improves a number of titles that haven't received a specific Pro patch. Before long, videos were being shared around the web, showing clear performance enhancements in games such as Bloodborne and Assassin's Creed Unity.

And now, Digital Foundry has decided to weigh in with its technical expertise, analysing a number of titles in the video that we've embedded above. The publication takes a good look at a bunch of games that launched before the Pro, including Knack - without its Pro patch, obviously - the aforementioned Assassin's Creed Unity, Killzone: Shadow Fall, and Battlefield 4.

All in all, Digital Foundry's very happy with what they find. In simple terms, Boost Mode allows these games to take advantage of the Pro's extra power, giving way to benefits such as better frame rates, reduced load times, and better texture pop-in. In some cases, frame rates are rather dramatically improved; in Battlefield 4's multiplayer, for example, Boost Mode keeps the shooter running at an almost perfect 60 frames per second.

Are you looking forward to trying Boost Mode when the update launches proper? Count some frames in the comments section below.
