Bought my girlfriend the surface pro 3 i5 version and it seems every game has sluggish input from the Xbox 360 wired PC controller. Even when playing apps it feels sluggish. Anybody having the same issues?
The drivers installed themselves as soon as I plugged it in.I haven't tried an Xbox 360 controller, but my Xbox One wireless controller is working perfectly fine on my Surface Pro 3 (i7 though, but that shouldn't matter much in this case). I don't really have the exact values in mind, but could the very reason possibly be, that transfer rates of USB 2.0, which is used on the wired Xbox 360 controller is far behind the transfer rate of wireless controllers? Just guessing though.
I've just removed the wireless receiver from my Surface Pro and connected the controller via micro USB cable. Just for testing purposes. I couldn't see any differences in performance. Since the XBO controller is no different than the 360 - at least from Windows' point of view - it might possibly be an issue on your end. Have you installed the correct drivers? 64bit?
