I have experienced issues regarding my Wireless input devices (Logitech Unifying Receiver mouse & keyboard, Bluetooth Wireless Controller) during gaming. Both receivers are plugged into USB 3.0 ports and in almost immediate proximity. When idle, or performing simple tasks like browsing the internet, all the devices have almost no latency. But, when gaming, they have sudden spikes of latency (up to like 50 ms, from the usual 1 ms). This happens for all wireless inputs, but if connected with a USB cable the same devices perform as they should, with no hiccups.

I assume that the processing of the Wireless Receiver signals somehow has a lower priority when under heavy load, which is what would cause such behavior. I might be wrong.

Any suggestions as to how to fix this?
