ASIO peaks when using Pensado EQ from Acustica

using the Pensado EQ on the master bus creates ASIO peaks and dropouts at buffer size 256 (RME UFX)l
Pensado EQ in C12 buffer 256

when i load the same project into Cubase 11 i do get a much lower ASIO load and no peaks or dropouts.

what to make of it?
