Subtle lag with Pro-L2 in Reason 11

Running the demo of Pro-L 2 in Reason 11, I get lag that puts the track out of sync. Settings within the plugin don't seem to change the lag for better or worse. Not exactly a pro setup here, but haven't had this problem before.

Windows 11
32GB RAM
12th Gen Intel Core i5
MOTU M, 44100, 512

I made a regedit entry to disable graphic acceleration for FabFilter, doesn't seem to have changed anything. Any suggestions?

Hi Martha,

Do you mean a lag, or just Pro-L 2's latency? Especially with oversampling and true peak limiting enabled, Pro-L 2 can introduce quite an amount of latency. Even though the host should compensated by the host, so everything will remain in sync, it can happen that you will notice a difference between what you see on your screen and what you actually hear. Disabling graphics acceleration does not make a difference. You could choose one of the styles with less latency, or disable oversampling and true peak limiting to reduce the latency.
