Reinstalled, restarting the sim after uninstall/reinstall/flight, WASM is release:release, don't know if it was debug before. Now the flight plan thing doesn't matter, but still a decent FPS hit. 10-25 at KLAX, whereas I get 40+ usually with other airliners.

Chiming in, registered just to post. i9-12900k 32GB RAM 3070Ti DX12 enabled Enhancement addon downloaded from Market. Loaded in to KLAX with no in game flight plan created, loads just fine, albeit with a minor notice to FPS. Loaded in to KLAX with an IFR in game plan created, slideshow + extended load time. Tested at KIAH as well, both cold and dark and "Ready to fly" on the runway, with the same results. Filing an in game flight plan, at least with IFR, seems to absolutely kill it.
