I got this with my new GPU, and I am actually quite impressed so far, apart from a few crashes I am getting, which I will look in to tomorrow
Performance-wise, it is pretty good, but not great for me. I am playing on High, with a few settings on V high, and in the field at the beginning where Psycho is guiding you, I get 80fps sometimes, and then it will drop to mid 40s, or even 30s!
Overall the game looks absolutely stunning, and I am enjoying it. Loving the environments so far, and the gameplay is great. Also, the lore is actually quite underrated in the Crysis games imo, and the story is shaping up fairly well too.
