Yes I do enjoy it very much overall, it's just a tiny detail but since everything else is so realistic and polished... I had to report it cause altimeter setting is a life/death matter in real life.
Well if it's a QFE then per definition the altimeter should read 0 on the runway. But if you set 29.85 as tower says in mission 4 you're still far from 0, still around 2200 ft close to H4 elevation of 2257 ft. That's why I guessed such small offset looked more like a QNH.
Actually I found a handy QNH/QFE calculator here https://www.sensorsone.com/elevation-station-qfe-sea-level-qnh-pressure-calculator/
With a QNH of 29.92 inHg as set in mission editor and H4 elevation of 2257 ft then tower should announce a QFE of 27.56 inHg ; )
