The latency graph in the article you post actually shows sporadic but substantial lag of around 100% (12ms to 25+ ms) with the wireless dongle. The average of all the lag might be low, but the lag when it does occur seems quite high. But in the real world, there can be even more lag. I've tested a bunch of different high-end wireless mice that purport to have super-low wireless lag, and they all exhibit lag in my apartment. Not constant lag, but sporadic occasional lag of like 600ms or more, every once in a while. For both clicking the mouse, or just moving the cursor. Because I've seen it on Mac, Windows, and Linux, and with fairly pricey mice from Logitech, Corsair, Razer, and others, I think the reason is probably radio interference. I live in a dense apartment block in Tokyo, and also have kids with a bunch of wireless crap of their own. Whatever it is, the only way I can have a mouse that doesn't ever lag is to connect it with a cable. I don't even play games, but the every-once-in-a-while lag is annoying enough when coding and web browsing that I now only buy mice that support wireless USB, Bluetooth, and USB-C wired connection.
