General bad Oculus Rift performance in Unreal Engine 4

Hi guys,

First of all, thanks you all for putting so much effort in troubleshooting the performance issue ! However I have tried everything I could find, and I’m not able to get above 40fps without going under 100 with “hmd sp” with really really simple demo. I have tried the following :

  • Both extended and direct mode from the editor
  • Checking the CPU usage thingy from the editor
  • Disabling realtime rendering
  • Tried the “hmd timewarp” command
  • Lowering the editor window when using “Standalone game”
  • I have tried the whole blueprint sequence from the post above while in direct mode
  • I have tried running demo without the editor
  • Lowering all the graphic settings down
  • Checking the “unbound” option of the PostProcessVolume
  • The “hmdwarp s” command doesn’t seems to exist anymore so the reddit post from eVRydayVR is not of any use to me (guy is awesome btw!)
  • Updating my video card driver.
  • Oculus runtime and the firmware are updated

Here are my specs :

  • ATI Radeon 6990m
  • I7-2790qm 2,20GHZ
  • 8Go

I’m able to run most UE4 demo from the following editor at a solid 75 fps in medium/high settings, and never had any performance issue on any DK2 demo.

I’m getting a bit desperate here, if you guys got any ideas, please let me know !
