@VFlip:
The only “UI” Lag I have, is when I want to assign a target to a steerpoint. Sometimes it I can’t click on anything else for ~30 seconds. After that it runs as usual and sometimes randomly lags when I click through targets to assign to a steerpoint(or cycle through the steerpoints in the UI). Radio chatter is playing as it should during the lag.

I have the same symptoms in both 32 and 64 bit.
