How do I prevent GeForce from making changes to Skyrim

Solution 1:

GeForce Experience is set to auto-optimize your games, which is why your games' settings change.

How to turn off auto-optimization

• Click on the cogwheel icon on the upper right.
• Select "Games" on the left.
• Uncheck "Automatically optimize newly added games" on the right.

How to manually optimize a game

• Click on "Home" on the upper left.
• Move your mouse over the game you want to optimize (in your case Skyrim).
• Click "Details".

• Finally, click "Optimize". You can also click on the icon to the right of "Optimize" to select a custom resolution or tweak how much the game will be optimized.

How to keep auto-optimization enabled, but revert a single game

• Select your game (Skyrim) as explained above.

• Click on "Revert".
