Does this affect game audio in general as well? I noticed on COD and PvZ if I don't have audio compatibility checked I get tonsss of audio stutter/static. Even with it checked I still get it occasionally and didn't know if my Xbox is just conking out or it was a problem with the response rate.
Yes, it can affect audio, and even framerates in some XB1 games. The console's just not built for 1000Hz input and XIM may be flooding the USB host with too much data, causing operating system issues that leech into the game.
Rather than use Audio Compatibility mode (which forces XIM Response Rate down to 125Hz), try using 500Hz Response Rate.
This isn't a problem on PS4 as the DS4 operates at 800Hz via Bluetooth, so it's reasonable to expect that PS4 has a 20% overhead (1000Hz) for smooth controller input over BT.
XB1's USB port functions at 250Hz, but the controller only responds to every second ping (refer to ConsoleTuner documentation for more info), so I'd be using 250Hz as the baseline for XB1 rather than 125Hz.
Like XB1, PS4's USB ports run at 250Hz. Jumping from 125Hz on XIM4 to 250Hz Response Rate on XIM APEX made a world of difference to my PS4 m/kb experience. Interestingly, I'm also having a better time with XB1 Smart Translators on PS4.
Ahh yes.
