So far, piloting an MH and AH-9 yields my vision shaking when getting up to higher speeds. It looks like the turbulence aspect of the advanced flight model is leaking over into non-AFM gameplay.
This shouldn't be in the non-AFM version of the game due to the mechanic feeling very out of place. If I want turbulance, I've got the AFM to try out. That's why it's there.
