Latency Chain: Where Delay Actually Comes From (End-to-End)

Input lag is a chain: device, game, frame pacing, display, and network. Map the chain and you stop wasting time on placebo tweaks.

Delay is not one setting. It’s a chain: input device → system → game → frame pacing → display → (for online) network. If you do not map the chain, you fix the wrong link.

The Latency Chain (Simple)

Input: controller/mouse, polling, wireless vs wired.
System: background load, scheduling, power mode.
Game: engine latency, settings, render queue behavior.
Timing: frame pacing and caps.
Display: mode, processing, refresh, VRR.

How to Debug Without Noise

Fix display baseline first (Game Mode, correct refresh).
Stabilize frame pacing (cap for consistency).
Remove background load and retest.
Only then tune input variables (polling, deadzones, curves).

Rule: fix the biggest, most consistent source of delay first. Do not tune inputs while timing is unstable.
