Turning logging off made a *big* difference for me. My system
is weak in the processor area (K6-2 400) but I have a GeForceMX.Right now
I'm flying over the ocean and I'm pulling about 20FPS, usually its 35-40.
On the runway I was getting 1-6, where as LaRCsim gets around 15-20.
Performance is way better though. I'll see what happens with todays code.
