Arkane Studios' immersive sim Prey finally has PlayStation Pro support.

The game launched on May 5, but Pro features have just today been added via a patch.

On Pro, Prey now features screen-space reflections, higher quality shadows, improved textures, anisotropy 16x (from 4x),improved visual fidelity, particle refraction, and more.

This isn't especially notable, except that when Prey launched, its retail packaging suggested that PS4 Pro support was included.

However, both reviewers and the general public failed to see any difference between the game running on PS4 and PS4 Pro.

"We could find no improvements whatsoever," wrote Digital Foundry at the time.

"The resolution remains identical, frame-rate is still locked to 30fps and even the lacklustre texture filtering is the same."

Bethesda responded by stating that Prey met "base requirements for PS4 Pro".

It seems that "base requirements" simply means "it runs on a Pro".

PlayStation's official PS4 Pro FAQ reads: "Upon its launch, PS4 Pro will make supported PS4 games look better and run more smoothly, while giving developers an upgraded toolset to create even richer, more detailed game worlds."

However, further down it states: Following PS4 Pro’s launch… virtually all new PS4 game releases moving forward will be able to take advantage of PS4 Pro capabilities on day one, or in some cases shortly after launch via a downloadable update. Some titles previously released will be updated to take advantage of PS4 Pro features."

Gameplanet reviewer Toby Hills was effusive in his praise for Prey, awarding it a 9/10 in an enthusiastic review.
