Interesting - thanks for sharing this detailed anolysis from your clearly very knowledgeable perspective.
How many of these areas that you found sub-par do you suspect are likely or possibly going to look better when we finally get to see screens from the PC version at 1920x1080 or higher resolution with higher res textures, better shadows, etc.?
Impossible to say. Judging from what they did with oblivion, and assuming they still have editable ini's in place, I would assume the pc version would look drastically better, sporting any shadow resolution you please, however the high setting (assuming you don't touch any ini stuff) would likely still be twice that, if not more, than what we see in these screenshots. Do take into consideration that if you set the shadows to something like 8096x the video ram would be severely impacted (probably need 3gb of video ram for that) , likely destroying most cards framerates in the process. There is also a high chance that the pc version will have the shadow's in the distance being rendered. And that would effect the overall look of the game greatly. The grass would also look a lot better with anisotropic filtering.
Also, on the pc version, those blurry rocks would be detailed and defined, thanks to x16 anisotropic filtering, in fact, all textures would have a far more defined no blur look.
Pc will also likely have slightly higher resolution textures, and stacking anisotropic filtering on top of that, with some super sampling aa (assuming the engine supports it) would make the entire game seem extremely defined, higher detail, and clean. The increased resolution on top of that, and you have, approx, a starting point of 500% gain over the console versions in terms of definition (at 1920x1080 and above), and assuming the graphics sliders are back, you will probably get a 1000% or higher improvement in overall output (and upwards to infinity with ini editing) . Do take into consideration that besides the sliders, this is true for almost all pc games.
Ssao and godrays however, well, we can't know anything about that until we get news on the pc version. There is a slim chance they will be included.
