[umag]

looks like DeadlockCode/n-body#1 that already applyed

[DeadlockCode]

I sadly don't have a MacOS machine so I can't test this myself and I don't really know anything about MacOS, but it's panicing when it's trying to get a physical device with Vulkan backend. According to some web searches, MacOS doesn't have native Vulkan support but that might be fixable by either a) installing MoltenVK or b) switching to Metal backend when on MacOS. If installing MoltenVK works then I'll consider this fixed but if not I'd like to know if changing this line to

backends: wgpu::Backends::VULKAN | wgpu::Backends::METAL,

solves the issue.

I have molten-vk installed - didnt work
i've patched quarkstrom in my fork - didnt work either

Will try to look into searches as well

@DeadlockCode changing ln135 does not solve the issue:

Ok Ive made it able to run DeadlockCode/quarkstrom@master...umag:quarkstrom:master but its slow

[J-Siu]

@umag Thanks. It works!!

[theDRB123]

I am getting the same error when running on wsl, cant figure out what to change...

Facing same problem here :(
