[yythlj]

目前的版本是基于4.3，gd4.4 dev1有个重大特征感觉很需要

物理插值支持3d，这个特性使得 网络游戏服务器可以15帧，客户端60帧而流畅运行

Godot 4.3 came with physics interpolation for 2D nodes, and now the 3D counterpart has been merged (GH-92391), with Ricardo Buring continuing the forward-porting of lawnjelly’s Godot 3.x implementation. Not only that but support for MultiMeshes has also been merged (GH-91818)!
