As great as this mouse is there are a couple trade offs and things I didnt know. these are not in number of importance. 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. I investigated using https://rzr.to/pollingrate from Razer. The results confirmed my first impression: ounces is still pretty lightweight though. It’s not quite as light as most honeycomb mice (the Glorious Model D, for example, is 2.40 ounces for the matte version) but still lighter than the MSI Clutch GM30 (3.46 ounces) or Razer DeathAdder Elite (3.70 ounces).
RGB is limited to a single zone which, of course, goes to the Razer logo. This is programmable via software (more on that below) but will usually be covered when using the mouse. Minimum Recommended Specs In fact, trying to run at 8K even caused some problems in Apex Legends. When making fast turns, my game would sometimes stutter like it was trying to catch up in frames. Considering the specs of my gaming PC, it shouldn’t be a hardware limitation. In my search for an answer, I came across reports from other gamers experiencing the same but the only consistent factor between them seemed to be that turning down the polling rate fixed the problem. In my case, dropping to 2,000Hz fixed the issue. I wasn’t as bad off as some, but clearly even high-end systems can experience issues. The Sensor Latency test was mistakenly performed with the polling rate set to 1000Hz. We've retested the Sensor Latency with the mouse correctly set to 8000Hz. For my first attempt I changed some BIOS configuration. I set the RAM settings to use the XMP profile.With all this in mind, 8K strikes me as a very forward thinking technology. Not all games or systems are ready for it and only very high refresh rate monitors are likely to see a big boost in performance. In my reading, I came across a number of gamers who claimed they could feel a noticeable improvement at 240 and 360Hz. I can’t say the same, but I’ve also never found microstuttering to be an issue at 144Hz. If you have, this mouse might be the answer. Everyone can use it, too. Much like the older models, this Viper is cleverly put together so that the unneeded side buttons won't be accidentally hit during play (the same is true of having the DPI button on the underside of the mouse, which is a decision I'm not a fan of but I understand the logic behind it).
With 8,000 Hz, I saw an improvement in my 300 Hz screen’s ability to show me the location of my mouse. Input lag tested slightly lower than 1,000-Hz mice, and my reaction time seemingly increased by a few milliseconds. How much you’ll notice this when gaming will depend on your skill level and how sharp your eye is.If it truly had any practical applications in gaming, then the highest DPI settings would be used by every eSports player,” Razer boldly states in its reviewer’s guide. Instead, the vendor thinks the combination of the Viper 8K Hz’s sensor, plus fast switches and polling rate will yield desired gameplay.
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. 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.

Some examples are the ‘Raw Input Buffer’ in Valorant and ‘High Precision Mouse Input’ in Overwatch.
The Viper 8KHz comes with Razer’s Focus+ Optical sensor. That’s a flawless one, and I found no issues with its implementation. There’s no smoothing, sensor deviation, or anything like that. The sensor isn’t really the selling point of this mouse, however. Yes, it’s flawless (and it goes up to 20000 DPI, which is far beyond what any normal gamer would use to be honest) but all recent gaming mice worth their money have a flawless sensor. The unique factor here is the 8KHz polling rate, so the question is: is it worth it? Razer Viper 8K – Design and FeaturesThe Razer Viper 8K feels like an old friend — and it should. There are virtually no differences between the original Razer Viper and the Viper 8K I’m reviewing today. That’s a very good thing, as the original Razer Viper is one of my favorite mice ever. It’s also good because the original Viper is being phased out and replaced with this upgraded version at no extra cost. It’s a medium-sized ultralight mouse (71 grams) that works well whether you’re a palm, claw, or fingertip gripped gamer. That versatility even extends to being a righty or lefty thanks to its 8-button ambidextrous design.Let me first say that this 8KHz isn’t some sort of ‘advanced edition’ of the regular Viper. It costs the same amount of money (at least at MSRP: of course local prices can vary) and is meant to just outright replace the regular Viper. To me that’s the right decision: it ensures that more people will get their hands on this new technology and it’s also a way for Razer to say ‘we think that this is the future.’ For wired mice, at least. Slapping this tech in a wireless mouse just isn’t feasible right now according to some Razer representatives, so I wouldn’t hold my breath waiting for a Viper Ultimate 8KHz anytime soon in case you were wondering about that. 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. Although I'd prefer it if the buttons not in use could be disabled via a simple press - as per the Corsair M55 RGB Pro - it's not a problem in most cases. As such, this could be a strong contender for the crown of best left-handed gaming mouse. Overall - should you buy it? We've added a link to the newly-reviewed HyperX Pulsefire Haste 2 in the Weight section of this review. That’s fine with me but for a mouse that’s so laser-focused on top tier competitive gamers I always like to see a set of additional mouse feet in the box. As per usual the omission of this set won’t influence my opinion on the mouse, but it’s a bit of a missed opportunity if you ask me. Shape, Coating, and Mouse Feet
