Yes, however, a small change of the cursor size doesn't work for me for the Neo lag (idk about the TV app). I have to set it to a size that is significantly bigger, to trigger the fix. (edit: Added that side note to the gist)
By the way if you are searching for some cross-platform FUSE-like alternative for a project I encourage you to try WebDAV if something else is your bottleneck.
It saved me some headaches from bundling an installer for macFUSE or Dokan's blue screens in the past. There are server implementations and also FUSE wrappers on GitHub. It's not perfect but worth a try. And it's supported directly by many OS.
Mostly used popular tools like Hopper, LLDB, Hex Fiend. Xcode's debugger UI was surprisingly helpful too because it lists current memory allocations of obj-c instances nicely. Also learned about Frida along the way and would have used it more in retrospect.
Mainly lived inside Chrome's dev tools for many nights. Its deobfuscator and debugger is very handy. Still scratched my head lots of times along the way.
Some interesting stuff is still missing, e.g. no idea yet how they get octant paths from geo coordinates.
That project seems to use some other kind of API. It does not handle real octree/3d data AFAIK. I've only seen quadtree and terrain elevation stuff there.
Can be done, although high LOD takes a while and the current implementation might eat up all memory. You can run it in parallel though. Shard by octants :)
