I honestly feel like I'm doing Linux wrong, because with one exception it's been seamless. No driver issues, no framerate problems, no game compatibility problems for anything I play. I thought I was having issues with Bluetooth dropping randomly, but I've tracked that down to a hardware issue with the antenna.

The exception is that my Wi-Fi chipset has a bad driver that I think causes it to sleep after every packet, meaning that my Wi-Fi speeds are so slow that a speed test times out. This isn't an issue for me because I was planning to be hardwired anyway, but if you're going to put it on a mobile device you should check your Wi-Fi hardware; I think a fix is coming soon, though.

In fairness, I'm not a cutting edge guy (I mostly play stuff a few years after it's released, patient gamers style) and I don't play many games that have any kind of anti-cheat. But I regularly get three-digit framerates on highest graphics settings.
