Blender 3.6 loads large geometries quickly. It means rendering starts immediately after changing the geometry or switching to the rendered view.
Meshes load 4 to 6 times faster, point clouds load nine times faster, and curves load ten times faster. Additionally, the Blender 3.5 “Light Tree tool” is much quicker thanks to multi-threading and support for instancing and builds up to 11x more quickly on an Apple M1 processor. However, an essential new feature in Cycles has been postponed in Blender 3.6: light link support.
Blender 3.6 now supports hardware ray tracing acceleration for AMD and Intel graphics cards in Cycles.
