Simhub latency is so down when i connect 2 displays

[alvarocastillop]

Thats append. Im using assetto corsa and I am trying to build a analog dash width arduino and simhub. For the moment i have connected a tm1637 for kmh and a rgb 16 led from rpm. When i connect only one of this displays, it works perfectly. But when i configured it from skech to use both at the same time, the latency is too bad and it refresh each 5 o 6 seconds.
Any solutions?? thanks a lot!!

PD: i dont hace a licency donator. I looked up that the FPS up to 64 when you have the licency instead of 10 fps.
