高CPU占用问题可能是由于Spine动画在Godot中每帧都在更新。你可以尝试以下几种方法来优化性能：

1. 调整更新模式：
   SpineSprite节点有三种更新模式：Process、Physics和Manual。默认情况下，SpineSprite会在每帧更新。你可以将更新模式改为Physics或Manual，以减少CPU占用。

      var spine_sprite = $SpineSprite
      spine_sprite.update_mode = SpineSprite.UpdateMode.PHYSICS

   或者，如果你选择Manual模式，你需要在代码中手动更新SpineSprite：

      var spine_sprite = $SpineSprite
      spine_sprite.update_mode = SpineSprite.UpdateMode.MANUAL
   
      func _process(delta):
          spine_sprite.update_skeleton()

2. 减少动画复杂度：
   如果你的Spine动画非常复杂，尝试简化动画，减少骨骼数量和关键帧数量。

3. 优化资源管理：
   确保你的Spine资源（如纹理和骨骼数据）已经被优化。你可以在Spine中重新导出这些资源，并选择适当的压缩和优化选项。

4. 检查Godot版本：
   确保你使用的是最新的Godot和spine-godot runtime版本。旧版本可能存在性能问题，更新到最新版本可能会有所改善。

5. 调试和分析：
   使用Godot的性能分析工具来确定具体的性能瓶颈。你可以在Godot编辑器中打开“调试”菜单，选择“性能分析器”来查看CPU占用情况。

希望这些方法能帮助你解决高CPU占用的问题。

uor99 I think your question has more to do with the specifications of Godot itself than with Spine. If you haven't already read the troubleshooting section of Godot's official documentation, please do so:
https://docs.godotengine.org/zh-cn/4.x/tutorials/troubleshooting.html

We need more information than that. E.g. your hardware specs, your operating system and version, whether you are using up-to-date GPU drivers and so forth.

Mesa3D is a software OpenGL driver, meaning the rendering is performed on your CPU, not your Intel(R) HD Graphics 620 GPU. Please install the proper Intel drivers.

uor99 不过，我没能找到更好的显卡驱动。

Please note that saying that you can't find a better graphics driver is like buying a motorbike and saying pushing it along the road is the best you can do, instead of starting the engine.

Please search the Lenovo website for your notebook model and graphics driver, I'm sure you will then find something better.
