@DeLaurec if you back up your user_settings.config file and then replace it again afterwards this should keep your settings. I’m not 100% certain about mods.
I’d also recommend booting the game up and checking to see if the stutter persists with a clean config before re-adding your old one though.
You can find your user_settings.config file here:
