Lmao! The PS4 won't run the games in 5k haha. It would be in 1080p. Everything would be upscaled
"lmao"? for what? Why would you run 5k mac in 1080p? 1080p 27" displays are less than 100$ today...
And downscaled (not upscaled) resolution, especially lower than x2 multiplier resolutions, looks awful on retina displays.
