Why 120Hz Still Feels Bad: The Usual Causes (Timing, Mode, Cap)
Why 120Hz Still Feels Bad: The Usual Causes (Timing, Mode, Cap)
Higher refresh reduces display persistence, but it does not fix unstable frametimes, wrong display mode, or hidden processing. 120Hz feels good when the whole chain is stable.
The Usual Causes
- Display not actually in Game Mode on that input.
- Unstable frame pacing (spikes and uneven delivery).
- Running outside VRR range or uncapped bouncing.
- Background load adding CPU spikes.
- Handshake issues (wrong port/mode/cable).
Fast Fix Order
- Verify 120Hz is active end-to-end (device + display).
- Enable Game Mode and disable extra processing while testing.
- Apply a realistic cap for stability (avoid wild bouncing).
- Remove background load and retest the same scene.
Rule: refresh helps only when timing is stable. Fix pacing before you chase settings.
