Review Of The Razer Viper 8khz

Review of the Razer Viper 8KHz – With higher polling rates on gaming keyboards (such as the CORSAIR K100 RGB’s 4000Hz polling speed), there was not much to have in the mouse agency. At least until the Razer Viper 8KHz arrives.

With an 8000Hz polling rate, its Razer Viper 8KHz will be the multiplayer game of choice for many esports players. Is it, however, an unfair advantage over gaming mice with a standard polling rate of 1000Hz? Does this render the  Basilisk Ultimate, Viper Ultimate, and DeathAdder V2 Pro, among other great Razer gaming mice, obsolete?

Most likely not, but today we’ll take a closer look just at the new Viper 8KHz mouse.

Specifications For The Razer Viper 8khz

  • 8000Hz HyperPolling Technology by RazerTM is eight times faster than some other leading gaming mice.
  • Fine-tuned RazerTM Focus+ 20K DPI Adaptive Sensor for the pixel-perfect aim
  • There’s no risk of misclicks with the RazerTM Optical Mouse Switch 2nd generation.
  • Control is quick and easy, thanks to the 71g lightweight design.
  • Wherever you go, advanced onboard memory allows you to customize your settings.
  • Mouse made of PTFE (polytetrafluoroethylene). The fastest flicks make with the feet, which have almost no resistance.

Design And Features Of The Razer Viper 8khz

The new Viper 8KHz gaming mouse should feel familiar to Viper gaming cursor shareholders, both in appearance and feel (shape, width, length,  etc.). It’s an ambidextrous mouse, which means it’ll work well for both left- and right-handed gamers. It also only weighs 71 grams (excluding cable).

You can get those additional programs’ side buttons due to the apparent ambidextrous design, which you can utilize for something else. Its DPI Stage/Change switch hides beneath the mouse, which I dislike. Thankfully, I can use Razer Synapse to assign DPI cycling to the Forward mouse button, so everything is fine.

The RGB lighting on the Viper 8KHz is subtle, with only the Razer logo illuminated. It may disappoint RGB-loving gamers, but it keeps costs, weight, and distractions to a minimum.

It has a Razer Focus+ Laser sensor to intelligent features like  Asymmetric Cut-Off, Smart Tracking, and Motion Sync, and it can provide up to 650 IPS, 20,000 DPI, and 50G of velocity.

Every click begins to feel satisfying, bouncy, and accurate thanks to 2nd Generation Razer Optical Cursor Switches, which also have a longer lifespan. According to Razer, the switches don’t require a physical interaction to send an electronic current, so there’s no need for “debounce delay,” according to Razer. In short, the switch responds instantly to every press because it registers the trigger with an infrared light beam. When you write one’s shots sooner, you have a distinct advantage.

I’m pleased to report that the cable drags minimally on the desk, and that’s one of the cabled mice that I can happily plug into the edge of my PC beneath the desk. Some mouse cables are too heavy to keep dragging the mouse down or too light to feel durable.

When compared to the DeathAdder V2 Pro, which is a few millimeters wider, its Razer Viper 8KHz works perfectly in my hand when used for work and gaming. It’s most likely the mouse’s shape. But it simply feels more comfortable and operated for more extended periods.

And here’s what I like about Razer’s mouse over the CORSAIR, HyperX, and SteelSeries mice I’ve reviewed: the grip seems to be much better thanks to the tire grip material upon those sides. Most mice can feel slick to a fingertip gamer without these rubber grips, and some manufacturers offer anti-slip grip tape, but it doesn’t feel quite right.

The Razer Viper 8KHz mouse is very comfortable to hold, and thanks to the .tire and its lightweight design and good feet, it glides effortlessly across my Razer Gigantus V2 touchpad mat. The mouse’s behavior is consistent, and I’ve never even had a point in time of frustration that I could blame on it.

However, you’re probably curious about its 8000Hz polling speed. After all, it’s most likely the main reason you’re interested in this mouse.

The mouse could indeed send up to 8 times more abundant inside a second with a truthful 8000Hz polling rate, reducing the delay from 1 to 1/8th of just a millisecond. It is essential to have faster refresh rate monitors (such as 360Hz), as the mouse could send extra existing information to match the display’s the frequency/refresh rate. Avoid Micro stutters, which you do or don’t notice.

When you perform a fast-paced FPS game such as Overwatch, CS: GO, or Valorant, a lower polling speed means slowdowns and more micro stutters, and this is especially noticeable. If you don’t believe me, please set your cursor to 500Hz or, at the very least, 125Hz and see what a difference it makes.

As an esports or competitive playmaker, you want every advantage you can get, even if it’s only a millisecond. Out-of-sync scenes, micro stutters, and delays are all items on your list that you want to eliminate as much as possible.

Unfortunately, as appealing as this sounds, polling at 8000Hz uses more CPU resources than 1000Hz. While playing games, you’ll notice stuttering and cursor input delay if your CPU isn’t powerful enough.

My primary gaming computer is fully equipped. AMD Ryzen 7 3800X CPU, CORSAIR DOMINATOR 32GB DDR RAM, and a GTX 3080Ti graphics card (GIGABYTE X570 Wi-Fi AORUS Elite motherboard and NVMe SSDs). I thought my PC was powerful enough, however after playing Overwatch, establishing the polling speed to 8000Hz caused an input delay.

However, I found a forum thread about turning off services or background programs. After trying this out with Razer Cortex (which also disables unnecessary Windows services and background programs while gaming)!

Overall, the aim feels seamless and responsive, and it’s a pleasure to use. Could indeed I spot the difference between a 1000Hz mouse and a regular mouse? I’m not sure, to be honest. It does appear to be smoother, but I’m not sure if this is a placebo effect. Setting the polling speed to 8000Hz does not make the layer fragile more frequently in the game. I also play on even a 144Hz BenQ EX2780Q larger screen, so I’m sure this would be more observable on just a 360Hz bigger screen and at an esports level.

There’s also the issue of game compatibility. By enabling “High Precision Mouse Input” in Overwatch, you can get an 8KHz polling rate, but you should check if your main game does as well. Although if your game doesn’t support it, setting its Razer Viper 8KHz polling rate to 4000Hz and 2000Hz is an advantage in and of itself.

Conclusion Of The Razer Viper 8khz Overview

Razer loves to claim the title of “World’s First” in any way they can, and even the Razer Viper 8KHz was without a doubt the fastest and most excellent mouse on the market, thanks to its 8000Hz polling rate.

Thankfully, Razer doesn’t raise the price just because the polling rate is 8000Hz. The price is very reasonable at AU$134.95 RRP, and the mouse has a tremendous good grip and excellent sensor performance.

To fully exploit the mouse’s capabilities, you’ll need a powerful PC with faster refresh rate monitors. Even if you plan to update your PC in the future, you can still get the Viper 8KHz right now. Even if you set its polling probability to 2000Hz or higher, 4000Hz gives you a leg up to those still using the classic 1000Hz polling rate.

The Razer Viper 8KHz seems to be a mouse designed for the present and the future. The mouse is available from Razer AU or various retailers across Australia.
