Hi. I worked on a couple of projects with rc1 and rc2 and the only plugin so far that acts weird when oversampling is Acustica Audio's VST: PINK42412 (Acqua) The Zero Latency (ZL) version they provide doesn't have that issue which seems weird. The PDC for the ZL version is 264/0/5120 spls (on this particular fx chain) and the regular version is 3257/1814/5120 spls. Tested oversampling a couple of other Acustica plugins and they all work fine so who knows what is the issue, probably on their end, gonna report it to AA but just mentioning here anyway.
