Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more! Input Lag Articles on Blur Busters.

There isn't enough conclusive data to give you a conclusive answer.
Refer to my "evaluating xhci controller performance" thread for more information.

You are completely ignorant what those terms mean, nor have you evaluated DPC/ISR performance on any non-AMD/Intel add-in cards using 1st party ETW-based tooling (e.g.: MXA)
Please stop sharing misinformation on these forums & read Microsoft documentation or engineers who're well-versed in this topic, thanks.
