Unfortunately you have jumped to the wrong conclusion. Perhaps I should have stated that I’m also running Nvidia 460.19 and since the 1.12.13.0 upgrade I’m getting excessive juddering and the flight experience is anything but smooth. It’s hopeless in VR, quite unplayable. That’s why I checked the frame rate and CPU usage. Much like you, if the sim is running smoothly, I’m not interested in the frame rate or CPU usage. So for me, it’s no placebo, just ineffective optimisation within the latest upgrade. Prior to that everything was smooth and judder free! To be honest I’m quite annoyed that an upgrade has turned in to a significant setback!
