This is a pretty well optimized port so I don't expect even a gtx 970 to have issues.I have two questions about this game, can a 970 and ryzen 1600 run this at 2560x1080 with adequate performance?
And more importantly, I broke my wrist last week and can't move my thumb, can I even play this game on m+kb or is controller recommend or the spacebar needed extensively?
KB+M controls are solid. You will need to use the spacebar quite a lot since it's your jump/climb button but since this is a slow paced game you should be able to get by using your index finger to press it when necessary.
