When operating Photoshop CS6 or CC you’ll notice a significant amount of performance boosts. A whole host of tools have now optimised application speeds.
This is all thanks to the new Adobe Mercury Graphics Engine. This works behind the scenes, tapping into your computer’s graphic processing and supercharging a set of special GPU-accelerated features.
Sounds impressive, but it’s on-screen that you really start to truly appreciate advancements.
Liquify in particular now permits massive brush sizes up to 15,000px, as well as increasing and decreasing brush sizes with shortcuts, on screen (Opt/Alt+[ or ]).
The Adobe Mercury Graphics Engine improvements also mean that Photoshop only installs a 64-bit version on Mac OS. 32-bit version is no longer available or necessary.
