The PlayStation 4 Pro upgrades are arriving en masse - to the point where it's very difficult for us to keep up here at Digital Foundry. We'll be taking a look at as many games as we can, and since many of the enhancements are simple resolution boosts, we've decided to put together a reference article that contains video analysis and a breakdown of the key enhancements - and 4K purists can also check out a companion article dedicated to native ultra HD titles.

We've moved our workflow on to 4K in order to fully capture exactly what ultra HD compatible formats like PlayStation 4 Pro and PC offer, but YouTube's high levels of compression makes getting a sense of the upgrade difficult in many cases. For that reason, we've recently launched a Patreon that offers access to everything we do in a pristine ultra HD downloadable format - h.264 at the moment, but we're currently researching HEVC for the same excellent quality with much lower download sizes. You can check out a sample at digitalfoundry.net.

In addition to covering as many PlayStation 4 Pro releases as we can, we'll also be updating with relevant patches that improve performance or add other features. We've recently revealed that the likes of Watch Dogs 2, Mantis Burn Racing and Deus Ex Mankind Divided had performance issues not found on the original PlayStation 4 and we're happy to report that patches have been issued for all of them, addressing our issues. In the case of Mantis Burn Racing, a native 4K at a locked 60Hz is confirmed and developer VooFoo Studios has also added HDR support too.

We'll be presenting these updates in the order that we look at them, with the newest coverage at the top of the page. We've had to split this guide into two pages, owing to its rapidly ballooning size, so here's the breakdown of titles.
