I use a controller on PC for games like this.
Yep. I have an Xbox One anyway so I've got a gamepad - the thing is upgrading my Xbox for a game means buying a new one, whereas you can always chuck more RAM or a better graphics card into a PC. The issue is the poor ports you get because the devs have to figure out how to get the game running smoothly on a whole spectrum of hardware instead of a fixed console.
For my part, I found a site that gave good suggestions as to what graphics settings you could turn down without really impacting the overall visual quality. The latest patch has also helped. The only area where I get any noticeable framerate lag now is the sections of Koboh with the deadly blue dust in the air.
I'll also say most of my earlier rants about jump puzzles can be ignored - on a replay they are nowhere near as bad or frustrating. I think only the bit on the Shattered Moon where you have to use the "bounce off one wall to another" climbing trick but there are steam vents that will knock you off (and you can't grab back on no matter how high you were) still got my blood close to boiling second time around.
