When I enable this, all gfx counters and pipeline statistics report that (almost) no primitives are culled, because the compute shader culls them before the gfx pipeline. > > There seems to be an AMD patent on the optimization, I failed to see it > mentioned, maybe it should be pointed out somewhere. > Unlikely.
