If you are using a mobile device or a Mac to access ETS2, these technical tweaks can drastically improve your frame rate and clarity: Truck Simulator 2 - Europe - App Store - Apple

The worst part of mobile truck sims is the artificial 80km/h cap. Look for a file named config.cfg or settings.ini inside the IPA's root directory. Change the line uset g_speed_limit "1" to "0" . Now you can legally (virtually) push your tuned Volvo FH16 to 150km/h on the Autobahn.

SCS Software, the developers of Euro Truck Simulator 2, have not ported the game to iOS. The game requires significant processing power and storage, and it relies heavily on keyboard/mouse or steering wheel peripherals that mobile devices don't natively support in the same way.
