How much does the Core plugin or the Cockpit Controls feature affect my game performance?

Very little.

The Core plugin only starts working after SimFly Pad switches to the Cockpit page and executes “Connect”. Because it uses update notification and asynchronous refresh mechanism, even when using a panel like B737 with hundreds of data variables, the impact on the game FPS is very small.

At the same time, since SimFly Linker and Core plugin communicate through API via memory, the efficiency of data transmission is also very high.
