Retrologue 2 massive cpu spikes c12

ive noticed if i load up retrologue 2 in cubase 12 im getting massive random spikes.
even if its just one instance with no other vsts or fx or samples the cpu meter maxs out at random times even if nothings playing and no change if the channel is frozen.
im using c12.10 and everythings updated its pretty much unusable and ive just bought the neon drift pack :frowning:
anyone having same issue?in c11 it seems its using way less cpu but all of the steinberg plugins seem too hammer the cpu in c12 .
