Cherrier Vivace Tachometer

I am having an issue where the tachometer on the Cherrier Vivace is very laggy. I have tried lowering graphics settings but that does not work. Does anyone know how this can be fixed?

 

There's 2 reasons for that imo :

1) in real life they act a bit 'laggy' too ( a)electronics can't keep up with actual rpm and or b)gauge is too accurate too display smooth flow)
2) In the controller file it's fps is set to 30, after I changed it to 60 it became a little more reactive

I think they are set to 30 to support lower end pc's and I think settting them to 60 does more benefit than opposite, although I'm
not 100% sure so *disclaimer here*
