yeah i play ksp and rainworld with coreboot+disabled ME thinkpad t430 and it's fine (coreboot has no performance penalties)

the only thing coreboot broke in my instance was the passive (cpufreq) powersave cpu scaler for my cpu, but I could just switch to the active (intel_pstate) powersave cpu scaler which is better anyway

are there modern desktop motherboards/chipsets/bioses that let you disable ME though? the z690/z790 are the only ones that I know can run coreboot (ignoring laptop motherboards), but I thought that still had to run ME?
