Just finished the game. Played great, ran great, looked great. Solid 60 FPS, at max settings. No slow downs, no bugs, no nothing. Loved every minute of it. Tons of fun, it's a great port. I had a more enjoyable experience on PC than on PS3.
Luckily this will encourage Japanese developers to make their games for PC more often and I have my fingers crossed for a PC version of MGS5 (Like that will ever happen...)
Well, the game was unlocked today and I pretty much played all day. Coming from a Japanese developer, this is the best god damn PC port I've ever seen. Plays great, looks great, runs great. Solid 60 FPS at max settings at 1080p on my aging machine. That game is also a ton of fun.
