This seems to be a problem after installing Blender Filmic, which was recommended to me (and it works very well). However, it seems to only want to do 16 tiles for cpu rendering, which is something I do not want to do. I heard that doing 256 tiles by 256 tiles is great to cpu rendering, and it is. For some reason, it just changed.
Will I need to uninstall it to get this back, or is there a work around?
