Mouse Sensor Tech: PAW3395, Motion Sync & Latency
Marketing terms like '26,000 DPI' and 'Motion Sync' are everywhere. But do they actually make you aim better? We deconstruct the tech to find out.
👁️ PAW3395 vs PAW3370
The PixArt PAW3395 is the current flagship standard, superseding the 3370. While the DPI increase (26K vs 19K) is negligible for humans, the real upgrade is Motion Sync capability and stability at high polling rates (4000Hz+).
| Sensor Model | PixArt 3370 | PixArt 3395 | Razer Focus Pro |
|---|---|---|---|
| Max DPI | 19,000 | 26,000 | 30,000 |
| Tracking Speed (IPS) | 400 | 650 | 750 |
| Motion Sync? | No | Hardware Native | Hardware Native |
📐 Sensor Position Physics
Front Sensor: Placed under the fingers. Increases wrist arc radius, making the mouse feel 'faster' and more responsive for micro-adjustments.
Rear/Center Sensor: Placed under the palm. Offers a 1:1 feel with arm movement but reduces range of motion for wrist aimers.
⚡ Switch Latency: Optical vs Mechanical
Optical Switches: Use light beams. Zero debounce delay (~0.2ms click latency). Immune to double-clicking.
Mechanical Switches: Use metal contacts. Require debounce delay (4-12ms) to prevent double-clicks. Can degrade over time.
