You are absolutely right. I forgot that G2 uses about 20-25% of power and performance by simply being active in WMR. Did the same flight with WMR shut down and was able to do 60fps with a few places where the fps dropped to 25fps (SU3 bug).
This begs the question. How many people forget to deactivate WMR and play games in 2D? This will cause about 25% of FPS loss simply by having G2 plugged in and active. I’ve been wondering why G2 takes up such high GPU utilization?
