Let me know if these images slow down your browsing, I'll change to links only if so.
Now, these Skyrim screenshots do not feature any fancy settings at all. There's no antialiasing, filtering or any ENB mods. At its height, textures are at highest setting. The point is to showcase that Skyrim supports resolutions up to and including 7680x4800; I do not know if you can override this, but whenever I tried a higher number the game crashed.
I must note here that I'm running this on a low-end integrated ATI Radeon HD 3000 Graphics card, and am thus limited to an FPS of around ≤1. I also don't have any WUXGHA monitor and had to run this in windowed mode, which made it rather difficult to know what I was taking a picture of. The majority of posters in this thread have a much better computer configuration than I.
Anyway, the first screenshot (in 7680x4800) is from Whiterun Stables. Sorry about the text.
The second screenshot (in 3200x2400) is from outside Whiterun Stables. I set texture resolution to Medium here, don't know what happened.
Running the game in this resolution didn't really drain much resources, I didn't notice any change at all. It took however a while to load the game, especially in 7680x4800.
My point with these images is that if I can with a very low-end card do this (and with high-res textures), it ought to look awesome with various ENB mods, antialiasing etc. enabled. Even if it may not be playable as one would like, it should still be very pretty to look at.
Just input whatever resolution standard you want in SkyrimPrefs.ini (should be located by default in Windows 7 under My Games\Skyrim) on:
iSize H=[Y resolution]
iSize W=[X resolution]
Then launch the game in windowed mode. Depending on your screen resolution, navigating the menu may be rather difficult. I simply opened the console and wrote "coc whiterunstables" in the main menu to be teleported there. Hence the default player character.
If I'm not mistaken, this is the first 7680x4800 screenshot of Skyrim in this thread.
