Investigate Godot Node multithreaded processing for potential more performance
hhyyrylainen opened this issue · 1 comments
I just tried setting all of the ECS nodes to use background processing and quite expectedly that crashes.
Still it seems like the full feature is not done yet in Godot: godotengine/godot-proposals#6424
And also there's probably more that could be attempted on our side to see if performance can be gained. Verifying if it could give more performance would be the first step for us, as our node processing doesn't really do the heavy lifting so if for example rendering or sound stream state update doesn't happen in multithreaded way with this option, it's pretty much useless for us.
Today with .NET 8 I just pulled in so good benchmark numbers that I'm no longer worried about the performance at all. But if this feature becomes available in Godot it would be nice to try anyway.
