This might be more problematic under CoreCLR than under Unity. Prematurely invoking GC will cause objects that are more likely to die in Gen 0 to be promoted to Gen 1, accumulate there and then die there. This will cause unnecessary inter-generational traffic and will extend object lifetimes longer than strictly necessary. Because live object count is the main factor that affects pause duration, this may be undesirable. It might be more useful to use OSU! approach as a reference: https://github.com/dotnet/runtime/issues/96213#issuecomment-2155746773 https://github.com/dotnet/runtime/issues/96213#issuecomment-... OSU! represents an extreme case where the main game loop runs at 1000hz, so for much more realistic ~120hz you have plenty of options.

If you could even just pass an array of objects to be collected or something, this would so much easier. Magic, code or otherwise, sucks when the spell/library/runtime has different expectations than your own. You expect levitation to apply to people, but the runtime only levitates carbon based life forms. You end up levitating people without their affects (weapons/armor), to the embarrassment of everyone. There should be no magic, everything should be parameterized, the GC is a dangerous call, but it should be exposed as well (and lots of dire warnings issued to those using it).

  > If you could even just pass an array of objects to be collected or something If you have a bunch of objects in an array that you have a reference to such that you can pass it, then, by definition, those objects are not garbage, since they're still accessible to the program.

    Yes. Use a WriteOnlyArray or whatever, Semantics aside though... There should be some middle ground between RAII and invoking Dispose/delete and full blown automatic GC.
