Latency overall was surprisingly minimal I tried playing in different areas of my apartment and didn't notice any difference.

Since this isn't a review of the Steam Controller, let's move on. So if you're planning to play FPS games primarily, then I'd suggest something different like a Moga Pro or something similar. Granted, I don't play shooters with a controller, but no matter how I tweaked the settings, I had a hard time. I tested Destiny 2, Overwatch, and Doom (2016) and while playable, I was not too thrilled with how it handled them. If you're familiar with the Steam Controller, then you'll know it's not well-suited to first-person shooters as a matter of fact, it can be downright awful in some circumstances.
