my brothers rig, (which was never great, even with 2.13) gets really weird in 2.14... He gets 40-50fps with detailed terrain off, which is perfectly playable.. the other day our squad is doing a bombing mission, and as is our want, we get everyone on the runway first.
with 5-6 sets of b17's with drones, sitting on the runway he was getting like 2-3 fps.. after climbing to about 1000 ft, his framerate goes back to 40-50, with the same amount of planes nearby.. just something weird about everyone on the runway in close proximity..
