I got the whole collection from the prime twitch rewards, but so far I've only played Infinite. Every time I load up the game it's fine but after a few minutes it starts stuttering, and it gets so bad I can't even move or do anything. I've tried to fix this by changing the graphics, disabling the GOG overlay and disabling Medal (which seemed to work for 5 minutes) and a couple of other things which didn't fix the issue.
