A friend, Lonn in the US, who emailed me with some questions regarding MSFS performance hit he encountered lately after he got his 7th Logitech FIP and my C172 CMP+Annunciator.  I think his case is worth a post to clear up some queries among those who are building their home cockpits with FIPs.

His questions here:

How many Fips do you run? I am getting a 7th and have noticed lately that my cpu usage is getting high on the Logiflightsimulator.exe or Logitech exe for the panels.

I also noticed certain gauges use more CPU intensive. Like the new Cessna 172 CMP I just bought from you seems to use alot of cpu compared to another asi gauge etc. How do you deal with it.

If I turn off the logitech panel drivers altogether I get better fps since the cpu isn’t bogged down. I know you run alot of panels and wondered how you work around this?

It seems the more complex the gauge set the more cpu that logitech exe takes up. Like the CH701 takes up nothing. But you start getting the eng on the 172 along with the hsi and the new cmp and the cpu usage is very high.

Man I am going to have to start planning my gauges around cpu usage. Any advise? Do you have this issue?
