Just installed 3.0 and was testing out cycles for the new speed bump.
I have a 12 thread machine and it only uses one bucket/tile for rendering. I have set the size of the tile to 64x64px which is my optimal default and ticked "use tiling".
I still haven't gotten rid of version 2.92, which does the multi-tile rendering using 12 tiles simultaneously.
Below is an image of rendering in 3.0 where it uses one bucket . This is on CPU mode, and GPU mode also gives the same one bucket result. Is there any way to remedy this or is this a purposeful feature for speed where all power is concentrated on 1 tile?
