More green. CPU sleeps when fifo HiWaterMark reached now. Showing more obviously when GPU become the bottleneck. Again, if it hurts perf -> GPU needs improvement where CPU load drop. I need to check some fifo stuff. TODO: test if HiWM are less reached with or without sending the whole fifoReadWriteDistance.
