I'm running the game on Ultra, and I've even gone into the SystemPrefs.ini to get (
http://www.rockpapershotgun.com/2011/11/11/getting-skyrim-skytrim/) some of those tweaks put it, but shadows cast in outdoors areas by stuff like trees and characters look like complete and utter arse. They're all jagged and blocky, and would've made me think of something being low-res, but I've screwed around with the shadowmap resolutions in the .ini, among other things, and set them as high as 4096 and haven't seen any change. In indoors cells, however, character shadows are neat and crisp.
I'll put up some screenshots when I get home tonight I hope, at work right now, but I was curious whether anyone's encountered similar behaviour or had any suggestions of what to try.
Edit: And here we have the screencaps. On the first one, indoors, you can see the character shadow is quite sharp and accurate. Second one is of the shadow cast by a tree outdoors, I don't seem to have something of the character on hand, but it gets the same sort of shadow, all blocky and stuff.

Your seems more like some sort of z depth bug or something. The previous iterations of the engine didn't seem to be able to handle rendering overlayed objects or subobjects featuring alpha transparency, I'm thinking what you got might be a glitch from having candles halo over the rug and maybe some sort of smoke effect as well? I dunno, I'm guessing this on account of the rectangular cutoff, maybe there was some other graphic there temporarily.

O_O. Looks like Skyrim does not do proper shadow map filtering. Don't know anything about DirectX ... perhaps some earlier versions (9 and below perhaps) cannot do it. What DirectX version do you have?
Hm ... does anyone else also have this problem? Ie. does Skyrim ever atempt to do proper filtering (aka, percentage closer filtering. Nvidia has hardware support for it but ATI does not and it must be emulated [patent issues iirc] - at least it used to be that way)? Indoor shadows do not count as they do not cover enough ground anyway.
Looks like DirectX memory corruption (iirc, the game is responsible in restoring what got corrupted). The problem should only exist in XP land afaik (starting from DirectX10 video memory is virtualized and corruption should not happen). Curious, are you on XP?

[Edit]Well I don't know if it does anything for the shadows but it sure as hell solved my freezing issues.

No, Windows 7. Only happens occasionally if I alt-tab back into the game though - starting up fullscreen is fine.

I'll have to check for the exact version when I get home tonight, but I believe my DX11 installation should be reasonably up to date. Running this on a GTX570, I'll try updating its drivers as well tonight, there's a new WHQL release from nVidia and I think my current ones are a couple of iterations old. I'll see if I can get some screencaps off others to have a look at how their shadows look outdoors.
In fact, if anyone here would like to volunteer a pic or two of outdoors tree and character shadows it would be much appreciated. :)
Edit: Actually, Skyrim is a DX9 game, if the filtering method you mentioned isn't available that would explain it. But only to the extent everyone else is getting this.

Dude's legit in my book, as I recall his mods were quite popular for Fallout 3 and New Vegas, I've used the one for the latter myself. I'll probably give his stuff a go at the weekend if it's stable.

Ulukai, something like this sometimes happens to me when I have a video paused in the background.
Ulukai on 17/11/2011 at 09:47
Definitely didn't have any media playing, I might have had a browser session running but would only have had ttlg open.
Anyway, not really an issue as long a I don't alt-tab too much.

I'll do you some when I finish work, got a 560ti so I guess it's similar to a 570?

Thanks, Ulu, that would be great. And yup, we should be getting similar behaviours out of the graphics cards.
