After more than a little teasing, Sony's PS4 version 4.50 update is almost here. The sweeping upgrade is now slated to arrive on March 9th, and is now confirmed to include that rumored Boost Mode for PS4 Pro owners. Enable it on the higher-end PlayStation and "select legacy titles" should run faster (or more consistently fast) without needing a Pro-specific patch. They may even load sooner, Sony says. The boost isn't certain to work with every unoptimized game, but it should do more to justify the Pro if you have an extensive game collection.
