Furthermore, let’s take a simple gaming situation. Scrolling through three horizontal screens at such a display resolution is a distance of 2560x3=7680 pixels whereas turning around in a 3D shooter is as long as 2560x4=10240 pixels. For a 400dpi mouse (or at a sensitivity setting comparable to that) the latter maneuver means 10240/400x2.54=65.4 centimeters of running! Even if the display resolution is decreased to 1280x1024 pixels, which is the native resolution of typical 17-19” LCDs, you’ll have to move the mouse by 32.7 centimeters, which is still quite a lot. Compare this to the DeathAdder’s 14.4 centimeters at the Ultra HD resolution and 7.2 centimeters at 1280x1024 (the mouse’s resolution being set at the maximum). So, here we come to understand what characteristics are important to evaluate a PC mouse.

For gamers who prefer low mouse sensitivity settings in games and who move the mouse vigorously and suddenly, the most important parameter is the maximum movement speed without loss of smoothness. Those 65cm of movement mentioned in the previous paragraph are not just an abstract illustration. For example, many gamers who play tactical shooters like Counter-Strike prefer low mouse sensitivity to aim with higher accuracy. In this case, moving the mouse by 50-60cm per second in several jerks is not an uncommon thing for experienced gamers.

Thus, the mouse is required to work well at sudden jerks. And the sensor of the DeathAdder is beyond competition in this respect, being 50% more skip-tolerant than the last generation of mice when you compare their specs. This is the reason for the marketing positioning of the DeathAdder as the best mouse for gamers who use low-sens settings.

For people who like high-sens settings (i.e. short accurate movements), the increased resolution of the DeathAdder might be enticing. It makes playing at high screen resolutions more comfortable.

According to Razer, the most sensitive sensors currently available have a real resolution of 2000dpi (one such sensor is employed in the Razer Copperhead and in the Microsoft Habu, for example). Higher resolutions declared by certain mouse suppliers (up to 3200dpi) are achieved by means of software interpolation. This allows putting a pretty number on the box, but has a negative effect on the consumer qualities of the product, particularly on the max speed without skipping. I can’t confirm or deny this information with data from other sources, so it’s just some thinking matter for you.

The infrared highlighting of the sensor helps avoid the influence of the surface as it is the case with ordinary sensors that have LED-based highlighting of a certain color.

Another performance-related factor of a mouse is the polling frequency of the USB port. In fact, it is the minimum time for the mouse to respond to your hand movement. Standard mice have a polling frequency of 125Hz, which provides a response time of 8 milliseconds. The DeathAdder works at 1000Hz, providing a response time of 1 millisecond.

First introduced by Razer, the Instant-On feature, which prevents the mouse from slipping into standby mode, is helpful, especially in games. Suppose you’re playing an online game. You have taken position in a nook with a sniper rifle and are expecting a potential frag to appear in the scope sight. You may pass quite a lot of time this way – enough for some mice to switch to standby mode, turning out their LED and not reacting. To wake the mouse up from this state, you have to jerk it rather hard (and lose the aim) and spend some time (enough for the frag to make off). You won’t ever find yourself in such a frustrating situation with the mouse from Razer – it is always ready for action.

As a matter of fact, for the few weeks of using the mouse I couldn’t find a gaming situation where the DeathAdder would fail me. It works perfectly whatever you do.

The mouse is equipped with 32KB of integrated memory for storing five configurations of settings. This feature was first introduced on the Razer Copperhead and later implemented in the Microsoft Habu and in the Razer Tarantula keyboard. The profiles are written via the driver interface, but are stored on the hardware and remain available even if the driver is not installed in the system.
