Rendering\D3D11\D3D11Context.cpp: Line 115
I was testing out 4K supersampling.
I was busy tweaking my settings to figure out the best trade off between visual fidelity, and immersion. I had disabled all traffic, and had most of my P3D visual sliders to around midway. The only plugins that I had active in P3D were my A2A aircraft. I was in my Piper Comanche 250. I had just closed my preflight inspection, and decided to go for a spin to evaluate my framerate around the airport. Not sure if the Preflight Window had anything to do with it but I did just close it using the X on the window frame as opposed to the one in the blue circle.
What was weird that after my preflight inspection I was not centered properly. Even after hitting the 'recenter' hot key, it would only recenter the direction that I was looking at but not my body position. So I was effectively sitting between the seats. I didn't really care as I just wanted to check the FPS.
I brought up the FlyInside menu while taking off and the last thing that I saw was that my fps were at 84 fps / 83 fps.
Edit: I was running P3D v3.3 and FlyInside v1.5.2
