It appears that Ubisoft's upcoming Far Cry Primal game will need quite a decent hardware if you are looking to play it at 4K/UHD resolution but it appears that it does not have issues seen on earlier Ubisoft PC ports.
Ubisoft had a lot of trouble with PC ports but it appears that Far Cry Primal will not have those problems although you might need a decent system to run the game.
While Far Cry Primal does not suffer from stutter, at least according to recent stream of the game, it runs at around 75 to 90 FPS on 1080p resolution with Geforce GTX Titan X graphics card. This was measured in one of the more demanding areas of the game and with most settings set at high.
The same stream showed the game at both 1440p and 4K/UHD resolutions where it managed to run at 60 FPS and 30 FPS, respectively.
Ubisoft's Far Cry Primal is already available on both Xbox One and Playstation 4 while the PC version should launch next week, on 1st of March.
