I'm non-experienced as coder too, but even user should - IMO - take much care, to filter out placebo effect, from regular gain. Also, it's possible, that andosbox got some options "locked" (no matter of config) for maximum performance, hence dropping support for games requiring other settings.

With dosbox, One can - like me - tweak settings for max performance, and, for games that have specific needs, just keep other customized config files too.

My question "if it is so miraculous and Open Source at the same time, why You think magic code would not be included in mainstream by dosbox devs, working hard on achieving best performance?" still remains. That is why I ask for rationale, not subjective user experience.
