controller input lag fix

Input lag — presses that register a beat late — is almost never a failing controller. It’s the transport (Bluetooth) or how often the pad reports its state (polling rate). Fix the link first.

Shave the delay between pad and screen

1. Use a wired or 2.4GHz connection
   Bluetooth adds 10–30 ms of latency and drops packets under interference. A USB cable or the manufacturer's 2.4GHz dongle cuts that to near zero. This single change fixes most "laggy" complaints.
   Inputs feel immediate next to a wired pad in the same game.
2. Set the polling rate higher
   Xbox controllers report faster via the Xbox Accessories app; DualSense supports 1000 Hz through its app or DS4Windows. A higher polling rate means the PC sees your inputs more often per second.
   The controller app shows the higher reporting rate active.
3. Disable double input processing
   If both Steam Input and the game read the pad, or a "wireless controller" and "Xbox controller" both appear, you get duplicated, delayed input. Hide the redundant device or turn Steam Input off for that title.
   Only one controller entry shows in the game's input list.
4. Reduce Bluetooth interference
   Keep the pad close to the receiver, off USB 3.0 ports (they emit noise), and away from Wi-Fi routers. A USB extension cable moves the dongle clear of the case.
   Held inputs stop dropping during play.

If wired still lags

A wired pad with delay points at the game’s own input buffer or v-sync, not the controller — check the title’s settings rather than replacing the hardware.
