Not surprising tbh, no automatic memory management solution is ready for realtime graphics - it always requires a lot of manual care to reduce memory management overhead (for instance working around the GC instead of using it), which then kinda defeats the purpose of the 'automatic' in automatic memory management. There simply is no memory management silver bullet when performance matters.
Perhaps I should've said this in the post to ward off comments from the anti-GC crowd but I do realtime graphics in managed memory languages just fine outside of the Wasm context. This is a Wasm problem.
