Its an ok game with some stunning and brave graphics, especially if you install HD texture mod. I play it for the grafics and locations alone. You dont need to do all the side quests except if you have ocd like I seem to have. The movement is a bit cluncky and you need to disable vsync, go borderless windowed mode and limit fps to 60 to get okayish input lag. Recently on linux hdr is broken again so I play sdr which still is okay looking.
Really the most annoying part is the clunky movement
