hi there is no 1080p @60hz option available in graphics menu (for me), down to 720p exclusive options are <30hz. but research proved there must be. system specs: i5 4690k @4,4ghz OC/3,5ghz (non OC)
16 GB DDR3 2666 Corsair
R9 200 (4gb) Sapphire Tri-OC Samsung EVO 240 Sony Bravia 66` 4k Windows 7 64 bit
this spec runs every game (of interest) smoothly (without fps drops) in 1080p @60hz, Dark Souls 3, Divinity OS2, WoW, Fallout 4 etc and was superior (due to OC) in benchmarks to comparable set-ups.
error check via Steam was negative.
