So whenever I try to change my skyrim graphics on the first window that pops up, and I click on OK, it doesn't save?

If you need more detail let me know!

Check the INI files in (My )Documents/(My )Games/Skyrim and make sure they're not set to read-only.

Im not sure how to check if they are read only. I can double click and I see some options and stuff?

Right-click on the files and click properties. Browse the tabs and option windows to make sure the read-only box isn't checked.

try that:

Delete the Skyrim folder with the .ini and saves ( in C:\users\USERNAME\my documents\my games). Starting Skyrim will recreate this folder.

After that open steam-> library-> right click on skyrim [Properties] -> Local files tab [Verify integrity of game cache...]

Will you loose your saves?

yes if you will delete entire folder no if you will only delete ini files there is no need to delete entire folder just delete ini files and rendererinfo file

if you are far in yes backup your saves. (sorry, not to mention it...)

i have problems with flickering shadows on the distant mountains when moving, i fixed the lines moving down when looking to the sky by using a bigger resolution. So can i alter the ini. file to fix the mountains?

i thing you have fix it with a bigger resolution !!!
