Hey Lichy, glad you sorted your issue

There is generally an argument over using the saveini command and the ini/inis created by it. Not everyone experiences problems it seems. I would recommend following the advice from the guy at tweakguides for editing your ini and making your game look nice. Everything he says is safe and works and he posts interactive screenshots that prove it and allow you to see the difference before you make the changes. http://www.geforce.com/Optimize/Guides/the-elder-scrolls-v-skyrim-tweak-guide is his whole guide.
Once those using all the extra stuff from saveini that makes your ini grow from 5kb to 45kb do the same I may recommend that, but not before.

Not discounting that guide...but all that guide changes are INgame settings....I have tweaked much more...

the settings i have changed do not show up in the Game settings..
I have disabled the Vanity camera...(well set it to one hour)good as disabled
Tweaked the Ram use
Thread use
many more settings are there to tweak...u grids, use HD cache, many more. (guess i just like the control of it all).
I was able to fix things (mouse on steroids in one direction) that otherwise was not fixable.
Is my game stable and fluent?....you betya...I rarely ever game less then 8 hour runs....yesterday was a 17 hour run.

did about 10 quests.
Today, I woke up early and plan an even longer run. my longest straight session to date is...http://i232.photobucket.com/albums/ee72/camaro_69_327/Skyrim19_hours32Mins.png. Lovin the Game!!

But all this is up to the individual. I have been using & tweaking this "New" engine since Morrowind.
