Looks like ...
Try upping AA and or adding AF....
Gamma correction?
What are your Specs...your right, the Screens (your and mine) , look way different...my settings..
Gamma correction OFF
AA/AF OFF in game settings..
Using Nvidia inspector to force..AA behavior flags = 0x 05 Skyrim
AA mode = Override application settings
AA setting = 4x
AA trans multisample = disabled
AA trans super sample = 2x
AF mode = user defined
AF filtering = 16x
AO compat = Fallout 3 (this is in the top setting in Inspector)
AO = Performance
AO usage = enabled
Frame rate limiter = 59
Tripple buffering = ON
Max prerendered frames = 0
Edit : you posted specs while i was typing...slow old guy...

Ok So I downloaded that program and matched my settings to yours and turned off AA and AF in the in-game settings. The only setting I couldn't find was "
AO compat = Fallout 3"That definitely helped a lot, but I still feel like there can be improvement. It's nice to see it looking better, though.
I'm going to post updated screen shots. The first is the current loading menu. The second is the back of my character, which I think looks too dark, like the contrast is too high, and I can't see anything that is on her. The third is just a landscape picture because I think someone asked for that.. And the last is just indoors in a shop.
Over all it's better, but things look a bit desaturated now and also dark. I turned the brightness up, but that didn't help any.
Thanks for helping me out so far, guys.

Your screen shots look a lot prettier than mine. I'm running on high settings. Is it because you are using mods? Also, AA looks like it is off for me even though I set it to 4x in the inspector program.
edit:
I turned off AF in the game and set it to 16 in the nVidia control panel and then selected high quality for AF. Colors are definitaly more vivid along with more detail everywhere. This setting allowed me to turn off AA and use FXAA which had been too blury when using the in-game AF.
I turned FXAA on and it looks a lot nicer. That fixed the problem that made it look like there was no AA (even though I had it on the nvidia settings to override.)
