Played up to Ch5 last night, pretty good. Feels very similar to what I can remember from MP1 and MP2.
Silky smooth @ 2560x1440 with everything maxed out on my GTX690
However, that being said, not sure if it's worth the 30GB download. Took about 2h to decrypt on Steam as well as I preloaded the night before. I mean it looks pretty good, but for that size I was expecting even better.
