So from what I can read, the Morrowind Script Extender uses LuaJIT instead of regular lua, which does tracing just-in-time compilation. Meaning, and I'm just paraphrasing wikipeda here, it compiles frequently executed sequeneces of operations into machine code.
This appears to use OpenMW, not MWSE
Now, that is a very relevant detail!
I did not know LuaJIT was even a thing.
Still probably not as performant as ... C++ or Rust or something, that is totally precompiled... but that would explain how this is even possible, a 3D Lua based physics engine.
Yeah, looks like LuaJIT passes a bunch of the Lua code into C, just good ole C, and then dynamically compiles it, then runs the 'translated' C code.
That makes a lot more sense lol.
