Well, some of you know i kept getting FPS drops in the STEAM version of Crysis 2, it turns out my STEAM version was a borked copy, [yes, i tried everything to sort it out, so don't bother with trying to justify it wasn't a borked copy, because it is] due to the fact i ordered the disc version from OcUK and it works flawlessly - DX11, Hi-Res Textures, everything on Ultra except Objects and Shaders are on Extreme.
Just giving other people a heads up if they experienced the same thing as me on the STEAM version of Crysis 2.
