VR Driver from Steam is considerably worse than native Oculus driver - stuttering/jerky

  • I normally fly FS2 in VR with the Oculus native driver and it is almost always amazingly smooth - just the best VR experience - 90 fps easily! However, I decided to try the Steam mode driver - wondering what we might see with the Pimax 8K X sometime next year. But I found a nearly unusable experience - very jerky and stuttery. I switched back to Oculus native mode and all is fine. Are any of you VR drivers seeing the same thing? BTW, I am using the Nvidia 385.41 driver.

  • I wonder how you switch between the two...? How do you know which driver you are using? Steam is always needed to use AFS2.

  • @J van E, on my PC, when I start by using the overall Steam Control Panel (Store, Library, Community, ...), then choose from the left side under -VR an app (Aerofly FS2 or CAP2), then PLAY, I get a popup dialog that lists both Launch ... in Oculus VR mode or Steam VR mode.

  • In Steam: upper right corner, click the Steam vr icon.

    More than likely, you will see the "headset not ready" warning.

    Pick up the headset and cover the sensor and the "headset not ready" warning will go away.

    If you were not able to before, you will now be able to click on Steam VR beta and receive a dropdown with lots of various settings.

    I'm not exactly sure, but I suspect some of these settings are affecting the FPS of Aerofly in Steam vr mode on an oculus.

    It might be profitable to play around with them to see what happens.

  • I've used both on Rift. I have a motion platform and to use the motion cancellation addon i need to be in steam vr. Its definitely worse as it has to do extra work to convert steam/openvr to oculus sdk.
