I had to agree with the logic of 5h4d0w. It works to find that file. I too tried the nvidia guide method(saveini), which screwed up my game after going from ugrids 7 to 5. Got the red loading screen and crashes even after returning backed up .ini . ** However a quick search of files modified by date showed ONE .ini file added/changed in the game data folder during that time. I deleted it and everything back to normal with ugrids 7. So only that deletion and the return of the backed up ini files is needed to put skyrim back to where it was before the attempted change in ugrids. And I'm using over 150 mods. Not sure if I will go to 5 now- but at least I know the correct way to do it (stupid obsolete nvidia guide...). Just wanted to test it to see if stuff like Warzones and a ton of other crap would play flawlessly on 5. It's ok on 7 but crashes occasionally. Many thanks to this thread for cluing me in to how to solve this!
