Graphics
Game settings
The slider sets the view distance: how far you can see before the fog. These are the game's own Graphics options, kept in your profile. Change them here or in the game's Options.
A quality preset sets the options above and below; change them after. In a race, F3 switches between this and the original look.
Profiles
Your profiles, settings and records are kept in this browser. Clearing the browser's site data erases them, so export a backup to keep them safe.
Important: leave the game with the X on the main menu. Closing the tab (instead of using the X) right after a save can still lose that save.
