1. Install game and run once.

2. Go to this location:
C:\Users\YOUR NAME\Documents\My Games\A Story About My Uncle\ASAMU\Config

3. Open ASAMUEngine.ini with a text editor of your choice

4. Using control+f search for
MaxSmoothedFrameRate

5. Change the value for "MaxSmoothedFrameRate=140" - or whatever you desire.
I recommend setting it a little below your monitor frame-rate, to avoid tearing.

6. Save and exit.

7. Start game and enjoy!
