Yes - with Beta 3, the issue I considered fixed and solved in my thread "SOLVED: Fundamental DR 14 bug report"
viewtopic.php?f=21&t=71032 has shown its ugly head again. Please see my last post to the other thread for details.

PS. Please, everyone - save your time and don't even try to look for the reason in my hardware. It hasn't changed since the first 15 Beta (if anything, another Titan Xp has been added). The cached files in DNxHR format are read from the same, super-fast, M.2 NVMe drive. So the culprit probably is still the same piece of code which BMD Resolve developers managed to fix between the Release 14.3 and the first 15 Beta; for whatever reason it's going south again

Just wanted to conclude this thread by referring to another thread of mine here:
