Football Manager 2021 Mobile contains two match engines, one of which – the ‘Enhanced’ engine - requires significantly greater processing power. The ‘Original’ match engine is also included for those with less powerful devices.
On first run, the game will detect which match engine your device is best suited to using and select this for you. If you would like to change which Match Engine your device uses, you can do this when setting up a new career, or from the Starting Configuration view of the Preferences screen. This change can only be made before starting a new career.
If you find the FM21 Mobile match engine takes too long to complete matches or seems slower than you would expect, please do visit our Bugs Forum and let us know the device you are using, as this will help with any further work we do in this area.
