ASUS’s Republic of Gamers peripheral series has recently released their second iteration to the Gladius Origin mouse. Sticking with the original physical characteristics, ASUS has revamped the optical sensor to a staggering 12000 DPI range, granting serious accuracy on all high end monitors. Key highlights of this product not only lays within the engineering of the drivers, but the ability of physically replacing the micro switches (which was also a popular option in the first generation). Of course it would not be a ROG product without a beautiful lighting presentation (covered in detail further on).

  • Scroll wheel with integrated ALPS Encoder
  • Detachable micro-USB cable with quick-release switch.
  • Mayan-inspired rubber grips on side panels.
  • Aura Sync lighting style (RGB).

ASUS ROG Gladius II Origin: A Closer Look

The Gladius II Origin is currently selling online for $83 (Amazon | Newegg). ASUS presents the basic operational parameters of the product on the box, highlighting the 12000 DPI optical rate and further outlines the much touted Aura lighting systems.

The Origin II possess a slightly taller and longer profile, providing a more comfortable fit with larger hands. Rubber padding with a slightly raised texture adorn the sides, for comfortable placement of thumb and pinky. On the bottom of the mouse in the last panel notice the inlaid 4 black rubber circles: screws are behind those for disassembly if Omron replacement switches need to be swapped out. (Pictures specifically take in low light to show off Aura lighting systems).

One of the more interesting aspects of the Gladius II Origin, is the implementation of a quick-release detachable mouse cord. It is located right under the mouse wheel itself via a mini-USB port, with two cord options: both two meters in length; one braided and the other coated in tough rubber.

Accessories include: two cords, extra switches, a ROG badge, and a convenient mouse travel bag. The bag is of nylon weave with a quick release cap on the drawstring.

ASUS ROG Gladius II Origin Details

The Republic of Gamers line of products takes customization, durability, and unique features an extra step. The Gladius II Origin receives the same treatment, this time in the form of replaceable Omron switches. Four screws, lift the top, and a quick swap is all it takes: practical and easy.

The Armory II Drivers encompass all ROG products in a single, stream-lined driver set. The primary core buttons panel is for changing the default mouse button layout. The performance tab is for much finer tuning, addressing angle snapping, polling rate, acceleration and deceleration, as well as button response time in milliseconds. The most prominent aspect is the DPI button located right under the mouse wheel: it is here where you change the DPI toggle (2 settings between three profiles each).

The Aura style lighting panel lends distinct transitions for RGB patterns including, static, breathing, color cycling, reactive, wave, comet, with adjustable parameters such as brightness, speed, and orientation. There is even a choice to sync all three areas (logo, wheel, base) with each other or run colors independently. The surface calibration screen features lift of distance adjustment and either preset or manual calibration.

If desired, customized and detailed macros may be set up per each profile at the macro tab. The sync tab is unique in the fact that it takes all ROG (and ROG Strix) products and synchronizes the Aura lighting effects across all devices. There is even a tiny color wheel to literally pick any color for the static and breathing effects. Note that when synced across peripherals all devices are locked and may not be further adjusted until this feature is disabled.

The stats panel reports Keystroke per Minute (for ROG keyboard) and Action per Minute (for ROG mouse). Interestingly enough there is also a Distance traveled indicator in centimeters for the mouse.

Clicking the tiny wrench in the top right of the Armory brings up Live Updates, for all ROG devices plugged in. A user may instantly flash the device to the most current firmware, in addition to auto launching the Armory and checking for updates every startup.

ASUS ROG Gladius II Origin Testing & Results

Testing Methodology

The Gladius II Origin was tested over a period of 240+ hours on a firm textured, plastic mouse pad. This type of mouse pad was chosen due to its unforgiving nature at higher DPI to put the optical sensor through its paces and try out the calibration feature. Settings of 6000 DPI with 1000 polling rate and angle snapping turned on was enabled for all tests: Adobe Photoshop for sensitivity and the most recent Doom for accuracy.

Test System

  • Processor: Intel Core i7-4790K
  • Motherboard: Gigabyte GA-Z97X-UDH5
  • System Memory: CORSAIR 16GB 1866Mhz
  • M.2. main drive with dual SSD
  • Video: Gigabyte GTX 970 G1
  • Monitor: ASUS PB328Q


This mouse has the ability to change polling rates per three profiles independently to 125, 250, 500, and 1000Hz. According to two polling measuring tools, Direct Input Mouse Rate (for Direct X) and Mouse Rate Checker, the Gladius II Origin exceeded the peak advertised polling rate. This is an imperative factor to ensure smooth and non-fluctuating operations: a mouse that is not able to lock onto a polling rate can not only crash a game out, but in rare cases bring an entire system to a halt.

Desktop Application: Using a native resolution of 2560 x 1440, the DPI used for all operations was set at 6000. The plastic, textured mouse pad is prone to catching dust and other particles, which makes it a perfect testing arena for higher DPI mice. No matter what was thrown at it (using lift-off distances to move, sliding recklessly, or the finest zoom-up work in Photoshop), the Gladius II Origin’s optical sensor dominated with ease. The most impressive feature implemented was the “angle-snapping,” allowing the wrist to hold the mouse at varying angles without affecting performance.

Gaming Application: This is what the Gladius II Origin was designed for and it shows. With precise tweaking to prevent under or over steering, it made aiming weapons incredibly fast and accurate. Even within a couple rounds of a frag fest in Doom, the difference and feel was very convincing and noticeable.

Optical Gaming Mouse Final Thoughts

The second generation of the Gladius Origin seriously ups the ante in the gaming arena. The updated optical sensor from 6400 to 12000 DPI alone is worthy of it’s successor. This lends the ability to use the mouse aggressively on high resolution 4K monitors with no issues, reducing the travel of the mouse overall and also fatigue in the long run. Even though the core physical design compared to the first iteration has not changed (only cosmetically), it was an overall wise choice considering the care that went into the independently engineered buttons.

ASUS ROG Gladius II Origin Conclusion

Performance of this product was not only precise and accurate at extremely high levels of DPI, but a special nod must go to the Armory drivers: the fine tuning of lift-off distance to the supreme angle-snapping feature was employed perfectly.

The appearance is another highly warranted aspect of this product, due to the Aura light sync system; providing an infinite variation of RGB colors (that can be customized) in addition to a wide choice of presets. To be able to sync three different color zones of the mouse independently or with other ROG peripherals does make an impact.

Concerning functionality, the Gladius II Origin keeps the standard tried and true six button lay out and adds the ability to swap out the Omron micro switches. For the extreme gamer or one who is highly aggressive with their mouse, this factor alone adds longevity, durability, and value. The construction is almost industrial (being very thick plastic) with the rubber side grips providing a higher margin of comfort. The independent button design is also worth mentioning again since it provided such accurate response time and ergonomics.

The ASUS ROG Gladius II Origin is currently available online for $83 (Amazon | Newegg). This is slightly the average for a gaming mouse, but do consider it comes with one of the best optical sensors and presentation in the ASUS line-up of ROG products. Recommended for a gamer that desires the best response times.


+ Incredibly accurate optical sensor (12000 DPI).
+ Attractive Aura light sync system.
+ Alps mouse wheel encoder for a positive stepped action.
+ The ability to swap out Omron micro switches.
+ Refined and streamlined drivers linking all ROG peripherals.
+ Quick release mouse cords.


– Slightly pricier (due to quality).


  • Performance: 9.25
  • Appearance: 9.00
  • Construction: 8.50
  • Functionality: 8.75
  • Value: 7.00

Final Score 8.50 out of 10.
