    Hello everyone!

    If you have a Motion Simulator setup with VR and you have trouble with the view moving along with your simulator?
    Then you are at the right place! OpenVR Motion Compensation compensates the motion of your simulator so your view is stable in your cockpit.

    Visit https://ovrmc.dschadu.de/ for instructions and download!
    I'm happy to hear any feedback. If you need help, post your question in this thread or fell free to join our Discord.

    Hey,

    a new version is released: beta v0.2.3.
    Download:
    https://drive.google.com/open?id=1dVCJZkU2HfYJSoJe57xzCqxaWp2Q2XZO

    Changelog:
    - Fixed bug: New connected device should now show up
    - Bypassing LPF Filter if LPF Beta = 1
    - Changed the +- button to increase / decrease in 0.01 steps, instead of 0.05
    - Changed the LPF Filter for XYZ to an exponential median average (DEMA) filter
    - Added "Samples" input box to UI
    - UI is slightly taller to fit the new input
    - Changed velocity and acceleration calculation. IMU values are discarded and then calculated with the new position values

    Still have to try, but feedback seems good!
    And it's a DEMA filter or did you kept the EMA?

    Been testing this for a good few hours now and it's amazing the difference that new calculation to the IMU position has made.
    No more little vibrations even with bass shakers!!

    Well done Dschadu!
    ...and also a big thanks to pmvcda for your help!

    I am going to test it this week end. I did a lot of efforts to get the small vibrations off, still not solved yet. So I am looking forward to the newest version @Dschadu posted above.

    I planned on buying the HP Reverb until I started reading up on motion cancelling. Very interested to hear if there are workarounds to make them work well with a 3dof simulator. Any news and thoughts are very appreciated!

    Hi @Dschadu

    Awesome work, just had a quick question.... this only works in the steam VR environment is that correct? just because I have a rift S and when I play say DCS and xplane they don't use steam VR becuase they natively support the rift. is there a way around this?

    Cheers and thanks for the hard work, much appreciated by all.

    Yes, is only works with Steam VR. You have to force these games to launch with Steam VR.
    Maybe some other Oculus users can help?

    Despite of the Windows Defender warning it works so far without any issues using standard settings, tested 20 minutes on Nordschleife, which is very shaky and bumpy.

    @Pit yes, but I'm waiting for some tester feedback. I don't want to post something broken :)
    It adds the option to disable acceleration and velocity values to address rendering issues with Oculus HMDs.

    @Dschadu Hello, Does this work for a 2DOF seat mover rig? Can I attach the controller to the sturdy non-moving part of the rig and have motion compensation work?
