Installing Razer Synapse almost defeats point of high end mouse… But because many games cannot handle high polling rate - i was forced into it. Right after installing Razer Synapse mouse turns heavy and less reactive when making small adjustments - it is hard to select unit etc. I always tried to avoid Synapse as it makes mouse movement literal shit… See nothing was done about this years too… And it is probably mouse movement logger… On every gaming forums also i hear ppl avoid it at all costs… IT IS JOKE!
