Turbo Boost is a motherboard / CPU feature, so Cubase is not ‘compatible’ or ‘not compatible’. As long as it works fine with the other system modules / features, Cubase will use the power available. I’m personally keep it enabled since Intel Gen.3 and only disable it for trouble-shooting (users’ cases) and testing.
Please, keep this on topic - I posted this to collect specific data about MMCSS. Thank you.
