I am going to link to my posts on twitter here: And: This hasn't been touched in the latest patch and it is the major bottleneck as far as I can tell when profiling. There are other instances of bad expensive shaders too. In Renderdoc for some of these, if you replace them with a fixed colour it doesn't really impact the overall look or change much (specifically the write to the big bad RGBA32 textures at the space centre which seem to not be correctly packed?)
