Strange... I'm playing very fluidly at Ultra graphic level, but on 720, as 1080 is playable but has stutter....
The thing is I'm using a GeForce 240!!! It shouldn't go this well! I'm so happy!

Those requirements were a bit overkill, for the recommended at least. With a 5770, I can run Crysis1/2/Metro 2033/'Witcher 2 on high/ultra at 1080P but I couldn't run Skyrim at that? Strange.
