Less CPU hungry VCV Rack alternatives?

I’ve been trying out the multithread version (totally distracting me from working lol), and on my 2017 MBP I can use framerate 30 and 3 threads to get what seems like much better performance, at least I’m able to screen record video/audio and patch/modulate/wiggle without glitching. Temperature is showing 137, however, the fans are not screaming atm. I do have the MBP on a cooling pad (which from what I read doesn’t help much at all).

I am interested in trying this out on my pc laptop as well and observing what happens.
