    After much digging, I've figured it out. There is an Vulkan setting that needs to be turned on to enable the legacy bundling method.

    With this on, the CollectedPSOs folder does get created along with the upipelinecache file. This flag works in both 5.5.3 as well as 5.5.1.

Hey Scott, 

I haven't tried this, but I meant to do it soon.
Could you please clarify the steps you took to log PSO and include them ?
At which stage you experienced it "not working" ? 
Best,
