Except FS2020 SDK, unlike XP11 for example, is not exposing the necessary data for it to work fine, which are the effective and actual forces on the simulated control surfaces (unless I’ve missed them).
On another topic than FFB but related to the SDK and what is “fine” in terms of peripheral devices, this video at 1’39" is showing the exact problem which makes DOF platforms useless to me:
VR in MSFS is starting to lose its luster for me - #74 by camer
When he is rolling to the left, the motion platform banks to the left, however in this case, it shouldn’t move at all with coordinated flight, or at least, it should have banked to the right instead to recreate the sensation of the centrifugal force. With this in mind now, try digging up all motion platforms or Yaw VR videos with flight simulation, most are wrong in term of physics, but they are right in terms of making a riding experience like in any amusement park.
