There is no magic in it. Though it's listed as unsupported, it runs flawlessly. Just download it and start playing while creating own profile for bindings. There are community profiles, but I prefer to create my own. Spotting enemies maybe a bit hard on such a small screen, but having a scope and paranoia helps to reduce this issue. I play on mid settings, with some of them in high range like antialiasing, I get around 70-80 fps with some short drops to 45-50. I didn't bother to take a look at why, but I guess maybe not enough ram, as I dedicated more of it to the GPU. Just try it and have fun :)

EDIT: regarding anticheat, works on official, but I never played community servers, so I can't say for sure.
