Flew my longest flight so far in MSFS 2024 - 1,939 NM from Mataveri (SCIP) to Carriel Sur Intl (SCIE). Flight time was 4.5 hours (flown in real time with no sim rate increase). Performance was excellent - mostly at 120 FPS - but the flight was over the Pacific at 37,000 ft, so not a lot to render. No stutters, landing was nice & smooth at ~ 90 FPS.
Low-level GA flying, such as around the Chatham & Pitt Islands was equally good, though with slightly lower framerates at times (ranged from mid 80’s to 120), depending on the view, terrain & clouds.
