With 4 GPUs, AFR will render as fast as possible. So each frame will be calculated faster than 2 GPUS rendering as fast as possible. MS delays from each frame drop down too about 12-15 per frame. But are still not totally in sync. But the latency from keyboard/input to Display will be increased by having 4 GPUS. Memory is only related to microstuttering if your out of framebuffer.
