raylib-lua is slow on Apple M1
Opened this issue · 6 comments
I'm on a MacBook Air (M1, 2020) running macOS 12.4.
After cloning the repo and subrepos and running make, trying to run any of the raylua_* binaries results in:
zsh: killed ./raylua_e
(…or raylua_s or raylua_r) and an exit code of 137.
Searching for "zsh: killed" seems to mostly result in pages relating to running Homebrew or tools installed with it on M1 Macs. I don't think this is Homebrew-related since I'm a boomer who uses MacPorts (if it ain't broke…). Nonetheless I wonder if the issue might still be related to the relatively new M1 hardware and I wonder if anyone else is seeing this issue happen on M1 Macs, or alternatley is running it successfully.
Unfortunately I no longer have easy access to Intel-based Mac hardware to see if the issue is happening there too.
Exit code 137 is out of memory error, not sure why/where it happens.
I don't have a Mac, so it's tricky to test, I should try with a vm.

Have you find out a way to work with it?
I'm afraid I haven't. I haven't had another look at this since I posted this issue.
I've submitted a pull request for the issue, but one thing I am noticing is performance is not great. Here is a benchmark I've run 100,000 bunnies, 144 FPS max.

I am not sure why LuaJIT is having these performance issues as I ran raylib_e with a zipfile to make a binary. The branch checkout is from 6 months ago so its a recent code base for LuaJIT. Even ran with MACOSX_DEPLOYMENT_TARGET=13.4 make to try anything for additional performance. Also used -arch arm64 -O3 -flto but nothing really improved performance.
I think this issue is due to LuaJIT on Mac OS not using JIT for some reason.
What gives jit.status() (may require jit = require "jit") on Mac OS X with M1/M2 ?
jit = require "jit"
print("jit status", jit.status())
./raylua_s examples/textures_bunnymark.lua
