Most professional FPS players use 400-1600 DPI combined with low in-game sensitivity. This provides pixel-perfect accuracy for headshots. Start with 800 DPI and adjust based on your mousepad size and comfort. Higher DPI (3200+) is generally not recommended for competitive FPS as it can reduce precision. The key is finding a sensitivity that allows 180-degree turns with one mousepad swipe while maintaining accurate crosshair placement.

Yes! Modern wireless gaming mice like Logitech G305 LIGHTSPEED and Razer HyperSpeed have ZERO latency difference compared to wired mice. They both offer 1ms (1000Hz) response time identical to cables. Many professional esports players now use wireless mice for the freedom of movement. The only consideration is battery life - ensure your mouse lasts through gaming sessions. Logitech G305 offers 250 hours on a single AA battery, making it perfect for competitive play.

Very important! Lighter mice (60-80g) allow faster flick shots and reduce wrist fatigue during extended gaming sessions. Ultra-lightweight options like Razer Viper Mini (61g) and DeathAdder V3 (59g) are ideal for low-sensitivity FPS players who make large arm movements. However, some players prefer slightly heavier mice (100-120g) like the G502 HERO for stability and control. Test different weights to find your preference - many modern mice like G502 have adjustable weight systems.

Optical switches use light beams for actuation, offering 0.2ms response time (faster than mechanical) and eliminating debounce delay. They're found in Razer Viper Mini and DeathAdder V3. Mechanical switches (like Omron) use physical contacts and are rated for 50-60 million clicks with slightly longer response (1-5ms). For FPS gaming, optical switches provide marginal speed advantage, but both types perform excellently. Optical switches also tend to have longer lifespan and no double-click issues.

Not necessarily. Standard 1000Hz (1ms) polling is perfectly adequate for competitive FPS gaming and used by most pros. The Razer DeathAdder V3 offers 8000Hz (0.125ms) which provides marginally smoother cursor movement, but the difference is barely noticeable for most players. 8000Hz polling also requires more CPU resources. Unless you're competing at the highest esports level with a high-refresh monitor (240Hz+), stick with 1000Hz for the best balance of performance and system compatibility.

Claw and fingertip grips are generally preferred for competitive FPS due to faster reaction times and precise micro-adjustments. Claw grip (Logitech G305, Viper Mini) offers a good balance between speed and control. Fingertip grip requires lighter mice (under 70g) for optimal performance. Palm grip provides more stability for tracking but is slower for flick shots. Choose based on your natural hand position - forcing an unnatural grip will hurt your performance. Test different mice and grips to find what feels most comfortable for extended gaming sessions.

Not always. Mid-range mice like Logitech G305 (₹2,699) and Razer Viper Mini (₹2,099) offer 95% of the performance of premium options at half the cost. The main differences in expensive mice are build quality, wireless technology, and extra features. For pure FPS performance, sensor accuracy and weight matter most - both available in budget options. Invest in premium mice (DeathAdder V3, Pulsefire Haste 2) only if you want specific features like 8KHz polling, ultra-premium build, or the lightest possible weight (under 60g).

Hand size matching is crucial for comfort and performance. Small hands (less than 17cm): Razer Viper Mini, Logitech G305. Medium hands (17-19cm): SteelSeries Rival 3, Logitech G502, HyperX Pulsefire Haste 2. Large hands (19cm+): Razer DeathAdder V3, Corsair Harpoon PRO. Measure from wrist to middle fingertip. Also consider grip style - fingertip grip works with smaller mice, palm grip needs larger mice. Most mice have dimensions listed on Amazon - check before purchasing.
