Description
I was experiencing very high latency playing with my dualshock 4 controller farther than normal from my computer, and googled possible solutions to this problem. While doing that I stumbled upon this reddit post, which suggests the usage of a udev rule to increase the polling rate for data from 4ms to 1ms.
This really solved my problem and the input lag was reduced significantly. Can those rules be added? I can make the PR myself, but I'm not so sure how to adapt the udev rules to the different dualshock 4 models.
Thanks for everything Valve devs, you folks are awesome.
