Its the equivalent to Intels Hyperthreading
It optimizes the processes for applications that run over several cores, but the MSFS is not yet optimized for this and cannot optimally use the processor’s performance, the result is higher temperatures with lower load.
If Hyperthreading (Intel) or SMT (AMD) is deactivated via the BIOS or via the Ryzenmaster, it can put the full power of the processor on one core, you have lower temperatures and it also boosts to more mega heart.
