What I'm about to say, doesn't get said often enough. There is a game that appears to be coded very well. That's right. Mirror's Edge Catalyst looks fantastic at 4K resolution - and it actually runs really well to boot. That is a miracle with today's game often being coded sloppy and developers expect people to upgrade their systems to run the game. Not the case with MEC. I've been playing it and it runs really well at 1080p on mid-range hardware as well.
In 1080p, the game ran with a minimum framerate of 70fps on Ultra settings. We did not experience any drops or stutters, so we’re almost certain that cards equivalent to NVIDIA’s GTX970 will be able to handle the game with constant 60fps at 1080p.
