External fxs stresses my cpu

Hi, I have recently started buying a lot of hardware effects, that I use in Cubase as External effects. I have the feeling that my setup, which is approximately 24 in out via a Motu 1248 and Adat converters (Rme) is putting quite a lot of tax on my cpu (M1 Mac studio ). I want to hear if there are some other possible solutions for an interface (Avid or similar) that would free up processing power, and if the operation of 24 I/O is as resource hungry as I expect.


I sonder if uaudio Apollo would help with the built in dsp
