“It’s not a great look for Apple that a Windows PC with a pretty wimpy GPU can run Anukari just fine, and the most expensive Mac M4 Max stutters, because obviously Apple’s hardware is incredible and just needs to be let off the leash a bit.”
macOS keeps the GPU clocked low because it does not recognize real-time audio as work. Anukari stutters on a top-end M4 Max and runs fine on a cheap Windows GPU. Apple offers no API to ask for more speed. A solo developer has to beg in a blog post.
