Hello,

Been playing Skyrim for a while now,and I see that grasses and some objects all have jagged edges and not smooth.Is there a way to fix this?

I have Antti Alisiaing at 4x,only for performance gains.But putting it at 8x does the same and no changes.

1) Are you sure that AA is working at all? take of screenie of a building roof (or something with angled lines) with AA off then with 4x. Some people with some vid cards and some configs have problems.
2) What gpu and driver version?
3) What game version? texture DLC?
4) post the screenie links...will help us figure out if this is a texture problem or AA problem.

MSAA is very poor at doing it's job at stuff like that (Trees too), doesn't Anti Alias everything. Your best bet would be ticking FXAA in the launcher however some people don't like the effect it gives (Blurring?). Test it out and see how it works for you, FXAA does a much better job at Foilage and stuffs.

If you look at the grass,it looks pretty weird.Is that how it is supposed to look?Also I tried FXAA,but everything is blurry,hate it.

As for game version,it is fully updated,no mods or DLC.

@ andy - I don't know what quality setting you have this set at...it looks like "medium" or "high" but not ultra. This is how the grass is supposed to look like. To improve, you have to apply special AA like transparency SS or the like, which is designed for things like grass. However, with your gpu, I wouldn't recommend it. Another strategy could be to apply Vurt's Flora Overhaul mod, which improves ground textures and applies 'thinner grass'...but again, there will be a performance hit that, I would guess, will be too much for that laptop gpu.

Install the dx9 files. (follow the readme) (drop them in the main directory)
Voila, no more jagged edges.

The Nanny is correct, MSAA doesn't work on transparent/alpha textures by design because it uses differences in the depth of geometry on objects to determine what to apply AA to and only applies it to edges. Transparent textures are just that, textures that don't have geometry to determine beginning and end-points, just portions that are opaque/translucent or transparent. You need either TAA (transparency AA for Nvidia) or AAA (adaptive AA for AMD) which are specifically designed to handle transparent textures by sampling them multiple times and compositing the image. TAA can be very performance expensive though, especially TSAA (transparency supersampling AA), and can be around the same performance hit as the base MSAA mode.

But personally, I would recommend FXAA. It carries a much smaller performance penalty (~10%, shader dependent) compared to MSAA and TAA at the cost of slight blurring of your image. But it handles AA on everything in the scene incredibly well, on geometry, shaders, transparencies, textures, everything.

I've been using this SMAA and love love love it. It isn't perfect, but imho looks better than FXAA and has a very low performance hit...during normal gameplay (as in not stopping to take screenies), it is nearly indistinguishable with 4xMSAA + transparencyAAx2. The selling point is the low performance hit for what you get.

You could use sparse grid x4 but its too demanding for that gpu. Normal trssaa works well for grass/foliage but svcks for dynamic snow. If you want to experiment download http://downloads.guru3d.com/NVIDIA-Inspector-1.94-download-2612.html.

Here are the settings I use with a GTX 460 768mb at 1360 x 768 AA x4/AF x16 (skyrim launcher) with Sparse Grid x4 (Nvidia Inspector)

fps= 40, constant and capped.

Supersample (SSAA) does the best job and gives overall better image quality with a large performance hit.

SGSSAA and other forms of SSAA are the best form of AA, but they also blur the overall image (some less than others, and some tweaks to mitigate this). The bigger problem however is they are incredibly expensive from both a GPU and VRAM perspective with a bigger performance penalty and VRAM footprint than the base MSAA+TSAA modes. If you plan on running higher resolutions with the high res texture packs, VRAM conservation is going to be important, so any deferred AA modes like MSAA/TAA/SSAA are going to be less desireable over shader-based AA methods like FXAA/MLAA, imo.
