Why does Oculus rift "poison" DirectX 9? RRS feed

  • Question

  • The new version of Oculus stops DirectX 9 apps from running after it is run once.  I must reboot my machine to get DirectX 9 services back.

    How to replicate the problem:
    1.Set LoTRO to run in DirectX 9 mode.
    2.Start LoTRO, it runs fine.
    3.Exit LoTRO
    4.Run Oculus app.
    5.Put on the Rift headset and view home
    6.Remove the headset
    7.Exit Oculus app (or not)
    8.Start LoTRO
    9.LoTRO startup will fail with message box DirectX 9 is unavailable
    10.Reboot machine
    11.Start LoTRO
    12.LoTRO runs fine in DirectX 9 mode

    This bug is reprehensible no vendor's software should ever disable another vendor's software.
