The Decision Framework
Choosing the best gaming mouse for FPS is messy because both top options are already excellent at core tracking and click speed. The real split is shape preference, software friction, and how much you pay right now, not headline DPI numbers. This guide compares the Razer Viper V3 Pro and Logitech G Pro X Superlight 2 in buyer order so you can pick based on your match routine, not marketing.
At a glance, the Viper V3 Pro targets players who want the lightest high-end option with elite latency and strong value when discounted. The GPX 2 targets players who want a safer, widely loved shape and proven tournament reliability, but often at a higher street price.
Step 1: Define Your Primary Use Case
Before specs, decide what kind of FPS player you are and what you refuse to compromise.
-
Primary tac FPS grinder (CS2, Valorant, R6)
Pick: Razer Viper V3 Pro
Why: Lower measured click latency in third-party testing (RTINGS: ~1.0 ms receiver) and lighter chassis (about 54 g) help with fast first-shot micro-corrections over long sessions. -
All-round FPS + daily productivity user
Pick: Logitech G Pro X Superlight 2
Why: The shape is one of the safest in the category, and Logitech’s click feel is more traditional for users who dislike ultra-light switch feel. -
High-volume aim training + marathon sessions
Pick: Razer Viper V3 Pro
Why: Lower weight reduces fatigue during repeated flick/reset cycles. In practical terms, that matters after the second hour, not the second round. -
Already invested in Logitech G ecosystem
Pick: Logitech G Pro X Superlight 2
Why: Better continuity if you already run G HUB profiles, Logitech keyboards, and shared settings workflows.
Short version: if your priority is pure competitive edge per gram and per dollar, Viper V3 Pro leads. If your priority is familiar shape confidence and ecosystem stability, GPX 2 still holds up.
Step 2: Compare Key Features
Both mice run 8,000 Hz wireless polling and flagship sensors, so the deciding details are in execution.
| Category | Razer Viper V3 Pro | Logitech G Pro X Superlight 2 | What It Means in Practice |
|---|---|---|---|
| Weight | ~54 g (black variant) | ~60 g | 6 g sounds small, but in low-sens flick-heavy play it noticeably reduces wrist load over long sessions. |
| Click latency (RTINGS) | Receiver: ~1.0 ms | Receiver: ~1.5 ms | Both are fast; Razer has a measurable edge for rapid tap timing and burst resets. |
| Max polling rate | 8,000 Hz wireless | 8,000 Hz wireless | Equivalent on paper. Real gains depend on your CPU headroom and monitor refresh. |
| Sensor max CPI/DPI | Up to 35,000 | Up to 44,000 | Neither number is the reason to buy. Tracking consistency matters more than max headline CPI. |
| Battery life (manufacturer) | Up to 95 hours | Up to 95 hours | Effective tie for most players at sensible polling settings. |
| Shape profile | Low-profile symmetrical, flatter hump | Symmetrical with slightly fuller center | Viper favors fingertip/claw agility; GPX 2 feels safer for users who want more palm contact. |
| Software | Razer Synapse | Logitech G HUB | Both are capable; both can be annoying. G HUB is generally simpler for onboard profile setup, Synapse exposes more tuning depth. |
In-game behavior check:
In tac FPS, the Viper V3 Pro’s lighter body and lower latency metrics make it easier to spam controlled micro-adjustments without overshooting. In tracking-heavy shooters like Apex or The Finals, GPX 2’s fuller mid-body can feel more planted for players who grip harder under stress.
Tradeoff reality:
Razer gives up some “plug-it-and-forget-it” simplicity, while Logitech gives up a bit of raw responsiveness per dollar at current pricing.
Step 3: Check Pricing Fit
Price is where this comparison flips from “close” to “clear.” MSRP is less important than what you can actually buy today.
| Use Case Budget | Best Fit | Current Price Signal (US) | What It Means in Practice |
|---|---|---|---|
| Around $130 | Razer Viper V3 Pro | Razer store lists $129.99 (discounted from $159.99) | You get top-tier FPS performance without paying flagship tax. |
| Around $160-$180 | Depends on shape preference | GPX 2 often sits at $179.99 at major retailers | If GPX 2 is full MSRP, you are paying mainly for shape preference and Logitech familiarity. |
| Waiting for sales | Tie | Both frequently drop at retail | If you can wait, buy whichever hits the lower sale and matches your grip style. |

If you need one line: at the prices above, Razer has the stronger value-to-performance ratio for most FPS buyers in 2026.
Step 4: Make Your Pick
Use this logic and move on.
- If your top priority is lowest weight + best measured click response, choose Razer Viper V3 Pro.
- If your top priority is shape familiarity + Logitech software/ecosystem continuity, choose Logitech G Pro X Superlight 2.
- If you are undecided and both are near full MSRP, buy by hand shape and grip style first, not spec sheet.
- If GPX 2 drops close to Viper pricing, the gap narrows to preference, not performance.
Buy if / Don’t buy if
- Buy Razer Viper V3 Pro if: you want the strongest all-around FPS performance value right now and play mostly claw/fingertip.
- Don’t buy Razer Viper V3 Pro if: you hate Synapse overhead or prefer a fuller center-hump shape.
- Buy Logitech G Pro X Superlight 2 if: you already trust the GPX shape and want minimal adaptation risk in ranked play.
- Don’t buy Logitech G Pro X Superlight 2 if: it is full price while Viper is discounted, unless shape fit is clearly better for your hand.
One clear alternative:
If you want maximum click responsiveness on a lower budget and can accept wired, look at the Endgame Gear OP1 8K. It is not as flexible for couch/desk switching, but its performance-per-dollar is aggressive.
