Improve performance

[Capewearer]

Godot community likes to have new features (that's okay, everyone loves shiny new stuff), but this engine lacks performance. Several rendering techniques aren't implemented, you possibly should to take a look for these issues and pull requests, because it's very unlikely they are going to fix them soon:

godotengine/godot#76291
godotengine/godot#74642

Unless these performance issues are caused by bugs, you should probably move this issue to Redot proposals

[JacobSyndeo]

@addmix It's not clear how to create an issue on Redot proposals… see #127. Also, going there directly via your link, I'm not seeing an Issues tab.

[addmix]

Guess it still needs to be set up... My bad.

Maybe also add SIMD support to basic vector and matrix types.

We're working on the proposals repo to hopefully improve the public facing suggestion and work interface.

Performance improvements are going to be on the radar, and I'll leave this issue open as the links to godot PRs on the subject are useful
