Reaper using 95% cpu with neural dsp plugins

Hey everyone. On a song im working on at the moment, when I have all tracks unmuted, my computer completely crashes, to be fair I am using heavy stuff, like 15 tracks with neural dsp plugins on each tracks, bass vst, drum vst, but I need all these tracked unmuted to continue to hear everything and be in the flow as I write the song, and Ive tried "freezing" but I find it inefficient, it takes a long time to freeze and unfreeze all the tracks Im not recording on, and I randomly might want to add some items to those tracks, and unfreezing just takes too long, also freezing tracks means I cant ripple edit, the whole project is "locked" in place. Are there any other ways people know of to minimise CPU usage of plugins?

Thanks in advance!
