It should be in the thousands. + +One quirk if you run these is that on a threaded renderloop, the animation one +runs faster than animators. This is because the work is broken into two major +chunks. One is doing the animation while the other is doing the batching in the +renderer and scheduling the rendering. If those happen on separate threads, we +get better parallelization so 'animation' comes out better. + +However, if you try again with QSG_RENDER_LOOP=windows in the environment, +you'll see that if it all happens on the same thread, then animators are a bit +cheaper (because they are simpler). |
