Competitive FPS players don't complain loudly when a mouse is almost perfect. They just quietly switch. For years, Logitech's G PRO X Superlight dominated tournaments because it stayed out of the way—light, fast, predictable. But there was always a silent compromise baked into its symmetrical shell: not every right-handed player truly fit it. Fatigue crept in during long scrims. Micro-corrections felt harder than they should. Logitech noticed—and instead of chasing lighter numbers or louder RGB, it corrected the shape.
The G PRO X Superlight 2 DEX isn't a flashy sequel. It's a philosophical shift. A right-hand–focused, performance-first refinement that asks a simple question: what if the best FPS mouse finally fit the majority of competitive players' hands, not just their desks?
That's the real story here. Not specs. Not marketing. Fit—and what that fit does to your aim over hours, not minutes.
Quick Verdict (TL;DR)
Buy the Logitech G PRO X Superlight 2 DEX if:
- You play competitive FPS (CS2, Valorant, Apex) seriously
- You use palm or relaxed claw grip
- You liked the Superlight 2's performance but never loved its flat symmetry
- You value consistency and fatigue reduction over gimmicks
Skip it if:
- You're left-handed
- You strongly prefer fingertip grip
- You already love the symmetrical Superlight 2 and feel zero discomfort
Bottom line:
This is the most refined FPS mouse Logitech has ever made—not because it's lighter or faster, but because it finally fits.
Logitech G PRO X Superlight 2 DEX Review: Design, Performance, and FPS Advantage
This mouse exists to solve a specific problem, and understanding that problem is key to judging whether the DEX is worth your money.
What "DEX" Actually Means (and What It Doesn't)
DEX does not mean:
- A productivity mouse
- A bulky ergonomic shell
- A departure from esports DNA
DEX does mean:
- Right-hand–optimized curvature
- Subtle asymmetry where it matters
- A shape designed to stabilize aim during long competitive sessions
Logitech didn't reinvent the Superlight. It rebalanced it.
Design & Ergonomics: Why Shape Matters More Than Weight
At first glance, the G PRO X Superlight 2 DEX looks familiar. Same minimalist shell. Same no-nonsense aesthetic. Same tournament-ready vibe. But put your hand on it, and the difference becomes immediate.
The Shape Difference You Feel, Not See
Key ergonomic changes:
- A gentle right-hand hump bias instead of a centered peak
- Slight thumb-side sculpting for lateral stability
- More natural palm contact without forcing a full palm grip
This isn't Zowie EC-level curvature. Logitech stayed restrained—and that restraint is intentional. The DEX still supports:
- Palm grip
- Relaxed claw
- Hybrid palm-claw styles
What it doesn't support well:
- Pure fingertip grip (too much rear support)
- Left-handed use (non-negotiable)
Why This Matters in FPS
In tactical shooters, most missed shots don't come from bad flicks. They come from micro-instability—those tiny corrective movements after the flick. A symmetrical mouse often requires more grip tension to stay aligned, especially during tracking-heavy scenarios.
The DEX reduces that tension.
Over long sessions, that translates into:
- Less thumb pressure
- Less pinky drag
- More consistent crosshair placement late into scrims
That's not something you'll notice in five minutes. You notice it after three hours.
Weight, Balance, and Real Control
Logitech kept the weight aggressively low, landing just under the psychological 60g mark. But the more important metric here isn't total weight—it's balance.
Balance Distribution
- Center of mass sits slightly rearward
- No front-heaviness during downward flicks
- No tail-drag during lift-offs
⚙️ Physics Impact:
Rearward center of mass = lower rotational resistance during vertical flicks.
Result: Smoother downward spray control (CS2) and faster aim resets.
This makes vertical corrections feel smoother, especially in games like Valorant where head-level micro-adjustments dominate gunfights.
Compared to the standard Superlight 2:
- The DEX feels marginally more planted
- Less "float" during fast resets
- More confidence when stopping on target
Sensor Performance: HERO 2 Without the Hype
Logitech's HERO 2 sensor is already well-documented, so let's skip the marketing language and focus on what actually matters.
Tracking & Accuracy
- Pixel-perfect tracking at competitive DPI ranges (400–1600)
- No noticeable smoothing
- Zero angle snapping
- Excellent surface tolerance
In practical terms: the sensor disappears. And that's exactly what you want.
⚙️ Tech Specs That Matter:
• Max IPS: 500+ (vs. 450 on Zowie EC2)
• Click latency: <0.8ms (faster than most pure opticals)
• Motion Sync: 0.02ms input consistency at 4K-8K polling
Translation: Your flicks land where you aim, every time.
Polling Rate Reality Check
Yes, it supports higher polling rates. No, it will not magically make you better.
What it does do:
- Reduce input jitter on high-refresh setups
- Improve consistency during rapid flick-reset sequences
⚙️ Polling Rate Breakdown:
• 1,000Hz: 1ms report interval
• 8,000Hz: 0.125ms interval
Impact: Smoother on 360Hz+ monitors
Cost: 3-5% CPU overhead
Sweet spot: 4,000Hz—same feel, 50% less CPU load
If you're on a 240Hz+ monitor, the benefit is subtle but real. If not, you won't miss it.
Clicks, Buttons, and Scroll Wheel
Main Clicks
Logitech continues refining its optical-mechanical hybrid feel:
- Light actuation
- Crisp response
- Minimal post-travel
Spam clicking in CS2 feels effortless, but more importantly, single-shot discipline remains intact. There's no mush, no accidental doubles.
This reliability stems from a fundamental engineering pivot in how Logitech handles click signals. To fully grasp the performance gap between Lightforce Hybrid and legacy Omron switches, one must understand that by removing mechanical debounce delays, the DEX achieves a level of temporal consistency that traditional metal-contact switches simply cannot maintain at 8,000Hz polling.
⚙️ Why LIGHTFORCE Switches Win:
Optical speed (no debounce delay) + mechanical feel (tactile reset)
= <0.8ms response + zero double-clicking.
Trade-off: Noticeably louder than original Superlight clicks.
Side Buttons
- Firm without being stiff
- Well-positioned for thumb access
- Zero pre-travel issues
They're not meant for MMO macros—and that's a good thing.
Scroll Wheel
- Tactile but controlled
- Slightly tighter than the original Superlight
- Excellent for weapon switching without overshooting
This wheel is tuned for FPS muscle memory, not spreadsheet scrolling.
Build Quality: Lightweight Without Compromise
Ultra-light mice often feel hollow. This one doesn't.
- No shell flex under pressure
- No creaks
- No rattles
The coating strikes a balance between grip and durability—less chalky than older Logitech finishes, more resistant to shine over time.
⚙️ Engineering Note:
Logitech uses thin-wall injection molding with internal ribbing.
Result: 60g weight + zero flex, without honeycomb holes that collect dust.
This is a mouse designed to survive:
- LAN travel
- Daily practice
- Aggressive grip styles
Battery Life & Charging (Brief, Honest Take)
Battery life remains excellent, comfortably lasting multiple days of competitive use. USB-C charging is fast and reliable.
⚙️ Battery Performance:
• At 1,000Hz: ~95 hours
• At 8,000Hz: ~35-40 hours
Recommendation: Use 4,000Hz for 60+ hour battery life with negligible latency difference.
Criticism?
Charging port placement could be more flexible for wired emergency play.
It's a minor issue, but worth mentioning.
Competitive FPS Use Case: Where DEX Pulls Ahead
This is where the DEX earns its name.
In CS2:
- More stable spray control
- Reduced wrist tension during repeated peeks
- Cleaner micro-corrections at head level
In Valorant:
- Improved first-shot confidence
- Less over-correction after flicks
- Better long-session consistency
In Apex Legends:
- Smoother tracking during chaotic fights
- Less grip fatigue during extended engagements
Across genres, the pattern is the same: less fighting the mouse, more playing the game.
At this point, the question isn't whether the Logitech G PRO X Superlight 2 DEX is good—it clearly is. The real question is whether its software ecosystem, long-term value, and competitive positioning justify choosing it over both its predecessor and rising rivals.
Software, Longevity, and the Competitive Verdict
Hardware is only half the story. In modern competitive gaming, the real difference between a good mouse and a great one often shows up after the honeymoon phase—when profiles, firmware stability, and long-term consistency start to matter. This is where many ultra-light mice quietly fail. The Logitech G PRO X Superlight 2 DEX does not.
Logitech G HUB: Minimalist, but Purpose-Built for Esports
Logitech's software philosophy hasn't changed much over the years—and that's intentional. G HUB is not trying to be flashy. It's trying to stay out of your way. It serves as the central control point for the

Over extended sessions—scrims, ranked grinds, or tournament prep—the DEX shape proves its value. The subtle ergonomic bias reduces the need for constant grip readjustment.
Result:
- Less wrist strain
- Less thumb pressure
- More consistent aim late into sessions
This isn't dramatic. It's cumulative. And cumulative advantages win matches.
Coating Wear & Shell Integrity
After weeks of use:
- The coating resists shine better than older Superlight models
- Grip remains consistent
- No structural degradation
Logitech clearly optimized the material for longevity, not just showroom appeal.
DEX vs Superlight 2 vs the Competition
This is the decision most buyers will face. If you are still on the fence about whether the newer sensor and switches justify the price, our in-depth
If You're Choosing Between Logitech Models
Superlight 2 (non-DEX):
Best for fingertip grip and ambidextrous users.
Superlight 2 DEX:
Best for right-handed palm or relaxed claw players seeking long-session comfort.
Performance-wise, they're equals. Shape is the deciding factor—and shape is everything.
Against Rival FPS Mice
| Spec | DEX | Razer Viper V3 Pro | Zowie EC2-CW |
|---|---|---|---|
| Weight | 60g | 54g | 76g |
| Max Polling | 8,000Hz | 8,000Hz | 1,000Hz |
| Battery (1KHz) | ~95hrs | ~80hrs | ~70hrs |
| Click Type | Optical-Mech Hybrid | Pure Optical | Mechanical |
Compared to popular esports alternatives:
- DEX is lighter than most ergonomic FPS mice
- More refined than many ultra-light newcomers
- More consistent than mice chasing extreme weight reduction
Logitech didn't chase trends. It refined fundamentals.
Expert Insight: Why Pros Will Quietly Adopt the DEX
Don't expect loud marketing campaigns or dramatic sponsor announcements. That's not how adoption happens at the top level.
Pros switch when:
- Their aim feels more stable
- Fatigue decreases
- Nothing breaks muscle memory
The DEX offers exactly that. It doesn't force adaptation—it removes friction.
That's why you'll likely see it appear on desks gradually, not explosively.
The Final Verdict: Is the DEX the New King of FPS Mice?
The Logitech G PRO X Superlight 2 DEX doesn't redefine what an FPS mouse is supposed to be.
It refines it.
By correcting the one long-standing compromise of the Superlight line—shape—it delivers a mouse that feels purpose-built for the majority of competitive players, not just adaptable to them.
If your priority is:
- Aim consistency
- Long-session comfort
- Tournament-ready reliability
This mouse earns its place at the top.
Minor Criticisms Worth Noting
No product is perfect. The DEX's weaknesses:
- Left-handed players excluded (non-negotiable design choice)
- Charging port placement could be more convenient for wired play
- Louder clicks than original Superlight (LIGHTFORCE trade-off)
- Premium pricing (~$160 USD) puts it above budget alternatives
These are minor compared to the core strengths, but they matter for specific users.
Frequently Asked Questions (FAQ)
Is the Logitech G PRO X Superlight 2 DEX better than the original Superlight?
In raw performance, they're similar. In comfort and long-term consistency for right-handed users, the DEX is a clear upgrade.
Is the DEX suitable for fingertip grip?
Not ideally. The rear support and ergonomic bias favor palm and relaxed claw grips.
Does higher polling rate actually improve aim?
It improves consistency and reduces input jitter on high-refresh setups, but it won't replace good fundamentals.
Can I use the mouse without Logitech G HUB installed?
Yes. Once your settings are saved to onboard memory, G HUB is no longer required.
Is the DEX worth upgrading from the Superlight 2?
If you've ever felt hand fatigue or instability with the symmetrical shape, the upgrade makes sense. If not, performance alone won't justify it.
Does 8,000Hz polling drain battery significantly?
Yes. At 8K, expect ~35-40 hours vs. ~95 hours at 1K. Most players find 4,000Hz to be the ideal balance.
HERO 2 vs PixArt 3395—is there a real difference?
Accuracy is functionally identical at competitive DPI ranges. HERO 2 offers better battery efficiency and more granular LOD control via software.
Can the DEX handle glass mousepads without issues?
Yes, but requires manual LOD calibration in G HUB. Set LOD to "High" to prevent tracking skips on reflective surfaces.
Sometimes the best upgrade isn't faster or lighter—it's simply a better fit.
