    I was stunned to see this video "The Best Racing Simulator At SimRacing Expo 2022":

    The rig hardly moves! Presumably no motion compensation required.

    I have heard previously that it is the sensation of movement rather than the magnitude that matters; but I want to feel more "realistic" (meaning bigger) movements. When driving through Eau Rouge at Spa, I want to feel how violent that is (which my rig does).

    What do you think?

    In my view 'best' is somewhat subjective and also very much dependent on what criteria is used to judge it.

    There was little in the video to justify it being the 'best', other than the company dialing in every aspect of the rig, game, VR and peripherals, which is important to all rigs. The offset seating position is interesting but perhaps not as flexible as a mid mount, given cars can be left, right or single seaters. Dialing in any rig/seating position depends on a bunch of stuff to exploit the fallibility of our physiological and psychological processing, and that goes for all rigs.

    Bigger movements do not necessarily equate to feeling more "realistic", particularly in VR, in circumstances where slower actuators are used. Motion speed and precision of movement are more important than just large range of motion when using VR and motion. Whatever motion range is used, actuator speed must be adequate to maintain precision of motion, there is nothing worse in VR than large wallowing motion, it can actually make people sick.

    From what I have learnt from many years building a few different motion rigs, is that for fast movement and VR (even small movements) good motion cancellation really improves the quality of the vision and therefore comfort/immersion. In the real world your neck and eyeballs will filter out most of the 'bouncy' movement of the car/rig/headset, which is not possible with the headset fixed to your face and no motion cancellation. Not saying that you cannot race without it, but once you have seen the difference its hard to go back. I now race with fixed screen which is very comfortable. That offset seating position can easily be simulated with different servo driver settings. Also big movement requires really fast actuators.

    When i built mine i thought i wanted big fast hard movements. I learned quickly it doesn't take huge harsh movements to translate the feeling of the road. Don't get me wrong if there is a jarring bump in the road i feel it but big sways or huge swings from traction loss are to much for me.
