Hi have anybody sucsessfully forced Antialiasing with Nvidia Inspector?
If you have can you please tell me how and such because antialiasing only works with in game settings for me!

Don't do it because it's incompatible. Just use x4 or x8 through the game and add some Mulitsampling or Supersampling though the NVIDIA Control Panel.

Edit: SSAA is the best but requires a good GPU. MSAA and SSAA are the best quality.

So its totaly impossible?
Really wanted to put some Full Screen SSAA in action!!

Skyrim uses MSAA anyway if you enable it in the options. All the NVIDIA settings do is add higher quality AA over x8 that Skyrim uses. FXAA is pretty poor quality.

Well but I dont want to use
Multi Sample Anti Aliasing (MSAA)
or
Fast aproXimate Anti Aliasing (FXAA),
what I want is
Super Sampling Anti Aliasing (SSAA) its a better but heavier form of Antialiasing(AA)
its like the Transparency AA that you can enable (TrSSAA) but instead of only work on the alpha channel in the frame it works on the whole frame!

I have turned off the AA and AF in the game and turned them on in the nVidia control panel with AA at 4, including transperancy, and AF at 16. I do have the FXAA option checked in game. Not seeing jaggies but I can't say for sure the control panel settings are doing anyting. There is a definite visual difference with the control panel AF being set to 16.

The AF settings in NCP works for the game textures get a little better but there seems to be no way of forcing anything else than Transparency AA in the NCP that is why I asked if anybody found a way to FORCE AA in the NCP or nvidia inspector.

By that i DO NOT mean FXAA that is crap its like applying blur and smudge the whole screen.
I dont want in game MSAA it works but its not the best!

I am asking for a way to force SSAA!

I found no way to force AA with Inspector as long as the game's internal AA was off. BUT it works perfectly if you set in-game to lowest AA setting (x2). Then, use "enhance application setting" and the MSAA x4 or x8 or whatever works properly...you will also be able to do transparency supersampling (the only thing that remains broken, I believe, is transparency multisampling).

I've found a good result (noticeable improvement without killing fps) to be:

in-game..... AAx2
Inspector...
Antialiasing Mode = Enhance the application setting
Antialiasing Setting = 4x multisampling
Antialiasing Transparency Supersampling = 2x supersampling

Take screenies of edged roof edges between each adjustment to make sure they work, and the degree of improvement next to fps hit.

EDIT - make sure the Antialiasing Behaviour Flag is not interfering..."treat override any application setting as application controlled" work for me. Incidentally, I also turn FXAA off.

just enable it in the NVIDIA Control panel under Anti-aliasing - Transparency and set to 4x (supersample).

BTW, you don't need to use NVIDIA inspector any more for SSAA because it's been officially supported by the NVIDIA driver for a while now.

@ Half64 - as OP is stating, his Inspector settings are not changing anything. I had this same problem (and some others did also), although I don't know if it is universal. My previous post was the fix that worked on my machine.

However, @ Bregell, you'll want to be sure that your Inspector is recognizing whatever launcher you are using, in case you are using 4GB or anything similar. To test this, is your SSAO or AF(x16 for example) having any effect when activated in Inspector?

Just do it in the NVIDIA Control Panel, that's what I'm saying, not the NVIDIA Inspector. I have SSAA enabled for this game by using 4xAA in the game settings and supersample through the NVIDIA Control Panel.

Ahh finally somone with a answer works as a charm
But Antialiasing Setting = 2x and 4x supersampling creates an awesome picture whithout totaly smooooooth edges on everything but [censored]s up the shadows and some other things making unplayable
gonna mixure with it a bit more thogh !

Fiddle with the blurshadow settings in the skyrimprefs.ini file. I like 15 with shadows in game set to high. Most people have come to the conclusion ultra for shadows adds little but has big performance hit.

Its not that issue!! Read waht I did!!
I forced 2x,4x,8x SSAA with the nvidia inspector and that really messed up the lightning!

Please everybody who thinks about posting here read what I am talking about, I am forcing diffrent full screen antialiasing modes on skyrim for best visual experience!
I do not talk about Transparency Supersampling, I am interested in Full Screen AA!

Back to topic:
Conclusions so far
For best visual experience use forced 8xQ Multisampling with 8x Sparse Grid Supersampling (Tranparency)

If anybody get Full Screen SSAA to work without lightning bugs please tell me how

You're confused. SSAA is fullscreen AA, MSAA is fullscreen AA and MSAA/SSAA are the best quality you can get that is official supported by NVIDIA.

Thay way nvidia uses SSAA is only on the alpha channel ie only transparent parts of the frame mostly textures like grass leaves branches, and MSAA is on all objects that is polygon based like houses and sutch.
But you can force the game to use SSAA on the whole frame ie transparent + polygonbased objects (=grass trees branshes houses swords characters (everyting)) this gives you a far superior image quality compared to MSAA.

Here is a little guide if you do not believe me! I am not comfused!
