The Uncharted games are pretty good PS4 speed games.

Co-op games you mean? There probably aren't too many that aren't also on PC. But perhaps that's not an issue.

If any ole' runs do, may I recommend Infamous First Light and Escape Plan. (Yes I run them, that's how I know about them) Especially Escape Plan. SUCH a good game, needs more than just my dumb ass running it.

Horizon Zero Dawn is becoming a pretty well-optimized run too.

Pure self interest but I would recommend Lords of the Fallen.

Not strictly a PS4 game (though again, we don't know if that matters)
