Specifically for a GTX980TI - Curious if this is likely to be a GPU/driver issue, or something on the Rift side of things...
Rift headset shows flashing orange light, static/white flickering. Occasionally, after restarting hardware/software, everything works perfectly for a few seconds- but the display flickers/cuts to black with even the slightest movement of the Rift headset. Touching/repositioning the cord has direct impact on blackout, exactly as expected for a faulty or inconsistent connection.
This connection issue is also present in occasional flickering loss of HDMI connection, and display flicker-on when changing USB3 ports. Rift sensor and other devices work perfectly in all USB3 ports - all USB/GPU drivers up-to-date, no hardware/compatibility issues.
I just checked my logs, and I'm seeing this error a lot too, is it something to be worried about? I haven't noticed anything wrong in this regard.
