Rendering 5000 sprites in UE4 10x slower than Unity5?

BTW. Did that test with t.MaxFPS set to 0, so it was capping at 60 Hz. Changing to t.MaxFPS 1000 for the 100K grouped test shows a frame time around 4ms / 250 fps, but that’s not a very meaningful number, need to keep adding work until you’re back in the target range.
