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