The 144 Hz requirement is more attainable, but Razer claims that the higher the refresh rate, the greater the benefits. This is a future-proofing mouse, and it’s best mate currently is, really, a 360 Hz monitor, which we’ve found to show noticeable improvements in speed and response compared to 240 Hz monitors. I didn’t have one on hand though, so for my testing I used a Razer Blade 15 Advanced Model, one of the best gaming laptops.

As great as this mouse is there are a couple trade offs and things I didnt know. these are not in number of importance. It makes sense — in theory. The Viper 8K reports its position 8,000 times a second. But there’s an important link here between your monitor’s refresh rate and whether a higher polling rate will even matter. Unless you’re running a 144Hz monitor, and maybe not even then, you aren’t likely to notice any difference whatsoever. Likewise, trying to run such a high polling rate actually has a noticeable impact on CPU usage, which is probably why this was the first mouse I’ve ever reviewed where the manufacturer sent me recommended system requirements: since this is ambidextrous, theres 4 total side buttons, one set on each side. Coming from a mouse with 3 side buttons and the way I had things mapped, I assumed I would be able to map all 4 buttons. wrong. the buttons are M4/M5 on each side. you have to choose if you are right or left handed in the app and that sets which side is being used and how they're numbered. kind of a bummer here but this is a personal issue not necessarily reflective of razer. coming from more to less is situational. I would just like that extra personalization. We've converted this review to Test Bench 1.4. This update modifies our Hand Size Recommendation test, adding a more granular hand size recommendation chart. We've moved several minor tests into different test groups, removed the Travel usage, and added a new Raw Performance usage. For more details, you can see our full changelog here. Under the hood, the Viper 8K has been upgraded with Razer’s latest Focus+ sensor. On paper, it’s a substantial bump in performance. The DPI has been boosted from 16K to 20K, the max speed has increased to 650 inches per second, and a quoted “industry best” accuracy of 99.6%. In practice, these upgrades won’t mean much to the average gamer (I couldn’t really feel them) but just might to competitive esports pros or those looking to break into the scene. This sensor also features Razer’s Motion Sync technology, which aligns the pulse of the mouse’s polling rate with the pace the host PC seeks updates to increase accuracy.This is just me theorizing, but if getting a perfect shape (for you) counts for a 5% performance increase and using an 8000Hz polling rate increases performance by 2% (I’m absolutely not claiming that that 2% number I got after my amateur scientific testing is representative for everyone: I’m just using these numbers as examples) you’re still better off getting a 1000Hz mouse that suits you instead of ‘just any’ 8000Hz mouse. If you do use Synapse, you can store an limited number of profiles, including with RGB settings, usable with the software open, and every profile will be able to launch automatically with specific games or other apps.

On to the mouse, then. I have never extensively tested a regular Viper but I did review the Viper Ultimateand Viper Miniso I have some experience with the product line. What immediately caught my attention when I first grabbed the 8KHz is how much better the buttons feel. I had no problems with the first iteration of Razer’s optical mouse switches (at least not on the units that I got for review) but it couldn’t be denied that they felt a fair bit less crispy than actual mechanical switches, and it feels as if Razer has really been working on that aspect.

Razer ups the polling rate of its Viper mouse to 8,000Hz for a more accurate rodent.

The reason for this is because of CPU use, it’s possible that 8K could actually lower your in-game FPS if you’re running an processor or graphics card. I'm a person who enjoys rgb and wish there was more. this is a non issue for most I'm sure, but this is about the only thing the steelseries had over this mouse was the customization options for rgb.
