Blender 3.1 takes a major leap in performance:

* Metal GPU backend support contributed by Apple for computers with M1 processors and AMD graphics cards
* GPU acceleration for Subdivision modifier
* Faster mesh editing
* Asset Browser indexing
* Image Editor support for large images
* Improved speed of .obj and .fbx export
* Better multi-threading, node tree evaluation and reduced memory usage in Geometry Nodes
* Plus many more performance improvements all over the board. New animation tools in the Graph Editor, new nodes for procedural modeling in Geometry Nodes, user interface improvements, Video Sequencer editor, Grease Pencil, hundreds of bug fixes and so much more.
