Hot diggity dog! It's even better than I thought under real conditions.

I could slow my program to 6ms even after adding USB and I'm still updating as fast as SimVar Watcher.

Problem was simple. I was piggy-backing my reads to the MSFS SDK on top of the USB Timer. I added a separate Timer (like I practiced in the previous post), and away it went.

Freaking awesome! Another major hurdle, but the worst is tomorrow. I have to mow the lawn, badly...
