i just read now a article about hardcoded scaling on linux, which is a maximum of 8 cores (or maybe even threads?) a few days ago also read that the cpu scheduler get’s an overhaul so i hope they fix this issue, too.

It’s a complete misunderstanding of what’s going on. The way the scheduler switches applications to ensure they all get prioritized equally was built with 8 cores in mind. All cores were always used.
