Hey @InfmsAviator I just did a flight tonight in the PMDG 737 from two of NZASimulation airports and did not notice this issue. Do you think we can talk through your settings? It looks like possibly your LODs might be very high as the main thread is spiking between yellow and red?
There may also be other Windows settings that you might need to tweak.
The good news is that with your setup you’ll have a very smooth buttery sim experience, we just need to work on it some to get you dialed in.
