Before I carry on reading this review I need to get something straight.
It really, really amazes me that a reviewer concerned with graphics can't understand a very basic principal of video game development in this regard. The graphics don't come close to Crysis 2 and Battlefield 3 in terms of visual fidelity because the data resources of this game are very different. It's very simple to understand. Anyone who has saved a JPG in a bigger resolution will know that it results in a bigger file - same concept with video games and textures. Similarly, higher polygon count (more detailed) models result in bigger files. The reason Crysis 2 and Battlefield 3 look better than Skyrim is because these games take up the majority of the 360 and PS3 disc space with high quality textures and models. Skyrim takes up the disc with the sheer *quantity* of models and textures there are in the game - content. Hence, lower resolution textures and models, which means the graphics will look slightly dated in some ways.
The PC version is bound by the same data restrictions as the consoles because the game has to be consistent across all platforms for all players to have an equal experience. Of course, better models and higher quality textures could be made for the PC version and are by the modding community, but for basic business reasons, this isn't the developers concern.
