We should only merge this once .NET 9 has been released globally out of RC, and the version of the global.json is update again to match latest release version.

Meanwhile, we need more people to test and see what has happened, e.g. performance regression/broken game functionality.

Pretty sure that's why this was opened as a draft.

I opened this as a draft precisely because .NET 9 is still in RC; I’ll update the global.json to the latest release version once .NET 9 is officially out. Meanwhile, I’ll encourage additional testing to check for any performance regressions or broken functionality.

There's some low hanging fruit you could probably add to this PR such as the new Lock object: https://learn.microsoft.com/en-us/dotnet/api/system.threading.lock?view=net-9.0

A quick find replace on object _lock has a a lot of hits that are free to update.

Those warnings about Lock being upcast to object will result in runtime failures. You need to update the method signatures to Lock as well when you pass instances around.

LGTM. Seems to give a 1% FPS increase on my setup.
