Will Render: Auto Tile Size be updated for 2.8 ?
Would love to know this too…
Cycles developers are looking for the user should not worry too much in the configuration of tile sizes. In 2.8 optimal tile size for GPU can be small, 64x64 is by default and it should not have much difference in render times compared to if you chose the size you usually use in 2.79b. This new small tile size in 2.8 also helped to CPU+GPU hybrid render with small tile sizes.
Not needed anymore
