Steps to reproduce:
Go to https://threejs.org/examples/#webgl_animation_keyframes
Tested in compatibility mode
Expected behavior:
Render the scene correctly and at a decent fps.
I get 30 fps in Safari and 35 in Firefox
Orion gives me 1-2 fps
also textures don't load properly so everything is black.
Orion and macOS:
Orion Version 0.99.108.1-beta (WebKit 613.1.10)
macOS Catalina 10.15.7 (19H1519)
Tested on my 2015 MacBook pro.
