Fix Input Delay in Browser Shooters

Quick Diagnosis

Mouse and keyboard actions feel delayed even when FPS appears acceptable.

Most issues are caused by browser focus, permissions, GPU settings, or extension conflicts.

Step-by-Step Fix

1. Close heavy tabs and background apps to stabilize frame timing.
2. Disable browser battery saver and high-efficiency tab sleeping.
3. Use fullscreen mode only if it improves frame pacing; test both modes.
4. Switch from Wi-Fi to wired connection if packet jitter is high.
5. Set monitor refresh and OS pointer settings to consistent defaults.

Notes & Fallback

Input delay often comes from unstable frametime, not low average FPS. Focus on consistency rather than peak numbers.

If embedded mode still fails, use Games Hub and launch the original host page from each game detail page.

Likely Root Causes

• CPU contention from background tabs creates frame-time spikes.
• V-Sync/frame pacing mismatch causes delayed visual feedback.
• Wireless mouse/keyboard polling instability at low battery levels.
• Browser process is throttled by power saver or thermal constraints.

Advanced Checks

1. Close high-CPU tabs and monitor task manager frame-time consistency.
2. Disable battery saver / low power mode and retest at plugged-in power.
3. Try wired input devices to isolate wireless latency layers.
4. Reduce viewport size and compare aim response under identical movement patterns.

How to Confirm the Fix

• Crosshair movement tracks hand movement without visible trailing.
• WASD strafing starts/stops immediately without sticky drift.
• Flick shots feel consistent for at least 3-5 minutes of continuous play.

If the issue returns, repeat the checklist after browser restart to isolate persistent versus session-only failures.
