laggy displays

[safir365 0]

Hi, I found that NGX displays are laggy compared to the real ones. In fact, on real displays, numbers transition and animation look more fluid :

 

I tried to set the ​the cdu fps limited on unlimited but it seems like the displays are fps limited anyhow.

I'm also using 2d gauges on a second monitor. Is there a way to get smoother displays, or to use any other external gauges with the NGX?
