PDADAPTIVE can get stuck at low frame rate and flicker.
Using UE4.14.3, I'm seeing an issue where with HMD PDADAPTIVE ON, and there has been a high render requirment, the frame rate is locked to 45hz rather than 90hz, the PD range has the capacity to brin...

I'm not getting any flickering, but it does lock you into ASW. I found three signficant flaws with PDAdapative. Was able to fix two of them, but not the third.
1) AdaptiveGpuPerformanceScale is missing the sqrt() as done in the SDK sample
2) The pixel density multiplication is applied twice when AdaptiveGpuPerformanceScale != 1. This is an issue with the bNeedsUpdate flag
3) AdapativeGpuPerformanceScale gives back values that are too high.
