Hey, found an actual solution (worked for me anyway):
1) Open steam
2) Open the Task Manager
3) Under the Details tab search for steam.exe
4) Right click and select "Set affinity"
5) Tick off 8 cores (i did top to bottom ones, no idea if it matters)
6) Open the game
7) ???
😎 Profit
P.S. change it back when you're done playing microvolts, just so shit doesn't break
