I know, it's still a puzzle. The thread is pretty long and I don't recall if it was ever stated that BIAB 2024 (and thus 2025) are fundamentally different in terms of requirements for the CPU than versions before 2024. They changed it so RealTracks regenerate much faster than before, but of course this requires more processing power. Yes, I know that's as far from MIDI as it gets, but combined with the picture of your processor maxing out, I think it's at least a good explanation why BIAB 2020 and 2025 might behave differently.
