The ROG Gladius IV Ace gaming mouse delivers next-level ergonomics and precision

When the pressure’s on and every flick matters, you need a gaming mouse built to keep up with your instincts. The ROG Gladius IV Ace is the latest evolution of our legendary Gladius line, redesigned through sports‑science research, tested with esports pros, and refined for competitive play. With customizable weight tuning, true 8K wireless performance, our AimPoint Pro 65K sensor, and more, the Gladius IV Ace gives you the precision, comfort, and responsiveness to dominate every match.

Ergonomics backed by research, tested by pros

Comfort is a competitive advantage, especially during long scrims and high‑intensity sessions. We know this better than anyone. That's why the Gladius IV Ace was shaped through extensive sports‑science research: we put sensors on pro players to analyze their movements and grip styles. This data informed the Gladius IV Ace’s design to help minimize muscle strain during repetitive, high‑speed movements. Its refined ergonomic form includes a wider palm rest and a taller rise so that it can support more of your hand naturally, giving you the stability and control you need for consistent aim no matter how long a match runs.

That comfort pairs with an ultra‑light 56g starting weight, giving you effortless speed right out of the box. And because every player has their own preferred feel, the Gladius IV Ace features modular weight tuning. With three different weights and eight ways to adjust the mouse’s heft, you can bulk your Gladius IV up to 71g. The ability to tinker with the weights helps ensure that the mouse performs in the way that best fits your setup and playstyle. You’ll get both a feather-light glide and precise stopping power, all without even a hint of compromise.

Precision engineered for competitive play

At the heart of the Gladius IV Ace is the ROG AimPoint Pro 65K sensor, delivering up to 65,000 dpi of raw precision with incredibly consistent tracking. You also get 11 levels of lift‑off distance customization, letting you fine‑tune how the sensor behaves during rapid repositioning — perfect for FPS players who rely on muscle memory and low‑sensitivity swipes.

Every click feels crisp and instantaneous thanks to ROG optical micro switches. They’re built for ultra‑consistent click force, instant actuation, and a 100‑million‑click lifespan, giving you the reliability to play aggressively without worrying about switch wear or mushy inputs.

One piece of feedback we’ve heard from players concerns click feel consistency between the two primary mouse buttons. Even a small variation in the required actuation force between those switches can be a noticeable, nagging distraction. We’ve refined our process to help ensure that the switches you receive with the Gladius IV Ace are a well-matched pair. It starts with an initial binning process at our switch supplier that sorts the switches by click feel. We follow up on our end with a proprietary click feel testing system that catches mismatched switches before they even leave our factory.

And when it’s time to glide, the large 100% PTFE mouse feet with rounded edges ensure smooth, low-friction movement across your pad. Whether you’re micro‑adjusting your crosshair or whipping across the mat for a clutch save, the Gladius IV Ace moves exactly how you expect it to.

True 8K wireless performance with ROG SpeedNova 8K Gen II technology

Powered by ROG SpeedNova 8K Gen II technology, the Gladius IV Ace delivers true 8K Hz wireless polling with ultra‑stable performance and improved battery efficiency. Expect 40% lower latency than last gen, minimizing interference during competitive play.

The enhanced ROG SpeedNova 8K Gen II receiver is designed to sit on your desk, close to your mouse, instead of tucked away behind your PC. That shorter signal path, combined with a larger antenna, gives you a stronger and more stable connection. It also keeps key status information visible at a glance.

Many setups judge your connection by distance alone, but the SpeedNova 8K Gen II's Smart RF Detection looks at the actual 2.4GHz interference around you instead. That distinction matters anywhere, but it’s crucial at tournament events, where dozens of competing wireless devices can crowd the spectrum even if your receiver and mouse are sitting inches apart. Colored LED indicators reflect that live reading: if the receiver's in a noisy spot, it shows red, and as you reposition it, the reading shifts to green as the signal environment improves, so you're placing it based on real data instead of guesswork. Once you've found the right spot, active channel hopping takes over, scanning ahead for clean channels before switching instead of bouncing around blindly. This results in fewer signal interruptions.

Beyond RF status, the two LED indicators can also be customized separately to communicate other information, like mouse battery level, DPI, or your active profile, so the information you want to see stays in front of you at all times.

When it’s time to take maximum advantage of the Gladius IV Ace and its ROG SpeedNova 8K Gen II capabilities, Zone Mode lets you instantly activate a competition‑ready mouse profile that optimizes polling, sensor responsiveness, and more. We've also added two new features to Zone Mode: frame-rate tuning and TX power control. With TX power control, you decide how much transmit power your Gladius IV Ace uses in wireless mode. Dynamic mode strikes a balance between connection stability and battery life for everyday play. And when you walk into a tournament room packed wall-to-wall with competing wireless gear, switch to full power and let your connection punch through the interference. You get peak performance exactly when the big match begins, and battery life to spare when taking a break from going pro.

Customization made simple with Gear Link

The Gladius IV Ace gives you deep customization without requiring software installs, but you can go even further with Gear Link. This web app lets you configure your mouse directly from a web browser. It’s fast, convenient, and perfect for players who want to tweak their gear across multiple PCs or tournament setups. For example, Gear Link makes customizing the ROG SpeedNova 8K Gen II receiver's LED indicators an easy task no matter what device you're on, so you always have the settings you want.

You can use Gear Link with a variety of ROG gear, making it a smart way to control your arsenal from one convenient interface. Check out our Gear Link FAQ for a rundown of compatible devices.
