Pretty sure still not resolved. I'll try bouncing out to Audition but that seems like a sub-optimal workaround. Just replying since I got an autoresponder about whether my bump was helpful - obviously not. Hopefully someone at Adobe will forward this. Thanks.
Hey, sorry Jeff, I'm just seeing this. Thanks for responding. I have my media on an SSD separate from the OS. In addition, I have an NVMe m.2 for my cache files. For this reason, I don't believe it's a hardware bottleneck.
I'll have to try other VSTs from different developers. It could be Melda's graphics acelleration or who knows what. Anyway, as far as I know, the issue remains. I haven't used Premiere in awhile.
