High CPU usage

Hi

I am seeing average 15% cpu usage for Simhub in game in AMS2 and other sims with an AMD 3400G. I've tried disabling all the Simhub modules one by one but it doesn't make a big difference.

I've done the CH340 fix and the 2019 driver is restored but it makes no difference and reported my old Arduino Mega as likely legit.

I only looked because I've seen FPS to drop significantly recently and I see it's pushing my CPU to 95%+ and FPS to drop significantly. 

I've also tried reinstalling Win11 and Simhub but it makes little difference.

I don't want to buy a new processor unless that's the main cause of the high Simhub usage level.

So is this high CPU usage level normal for Simhub?
