Due to the different technologies that are inside the 8KHz it weighs just a bit more than it did when it first released with a max polling rate of 1000Hz. This one comes in at 71 grams. That puts it just above the ‘ultralight’ category (we consider every mouse that’s 70 grams or less to be an ultralight mouse) but of course it’s still an extremely respectable weight.
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. In theory, it is more accurate. With a higher polling rate, it's sampling where your mouse is more regularly, and thus there will be times when it could mean you have the accuracy to kill, rather than be killed. Even writing that feels like a stretch though, and my own reactions and accuracy definitely don't stand up to that level of scrutiny. I've been using the mouse for around a week, and have seen no improvement over my main gaming mouse, an aging Logitech G402, in Apex Legends or Valorant. 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). For my first attempt I changed some BIOS configuration. I set the RAM settings to use the XMP profile.The Viper 8K Hz is specced for up to 20,000 CPI, a max velocity of 650 inches per second (IPS) and max acceleration of 50g. For comparison, we brought in two 1,000 Hz mice: Note: I have to configure the graphic card to use the MSI type of interrupts after every update of the NVIDIA drivers
Does Razer put its hertz where its mouth is? Before we could find out, we had to meet the Viper 8K Hz’s minimum requirements. Yes, this mouse has its own recommended specs. The 8k polling rate. this provides an extremely smooth mouse movement. this may be different from person to person. maybe mouse pads make a huge difference I have a relatively cheap one atm. One issue I've run into is Apex legends WILL NOT run a polling rate over 2000 on a 144 hz monitor. or at least not on mine. rainbow six siege I can crank to 8k and no issues. so maybe its game/display/system dependent I dont have a way to test it.I investigated using https://rzr.to/pollingrate from Razer. The results confirmed my first impression: As always I’d like to conclude this section with a disclaimer: I don’t know you, so I don’t know your preferences. You might have smaller hands and love large mice, or you might prefer super flat mice even with a palm grip. Always take these ‘grip and size recommendation’ portions by us reviewers with a grain of salt, as everyone is different. Buttons and Scroll Wheel 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. 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.
As such, the Viper 8K Hz is decently easy to move around for its weight, and the 100% PTFE feet on the bottom help. They provide a noticeable amount of extra glide, making the mouse as easy to control as the lighter (2.40 ounces) Roccat Burst Pro, but not more effortless to control than the super small and lightweight (2.24 ounces) Razer DeathAdder V2 Mini. 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. the wire on this is absolutely perfect. 0 drag, dont even notice it's there until I look down. dont have to use my cord bungee either. I almost got the viper ult but knowing how this mouse feels, it would've been a waste of money to me.
Buy it with
Doing the usual testing (shaking, squeezing, tapping) reveals that this is built really well. Nothing felt loose or annoying, and even when I applied as much pressure as I could the shell did not budge. This is one really nicely built product. Obviously I cannot comment on the actual durability (I don’t test these products for years) but from what I can tell there’s no need to worry. So here we are with yet another extreme spec that will force gamers to decide if they really need the boost. The Razer Viper 8K Hz is a successful implementation of an 8,000 Hz polling rate, but you’ll need a high-end rig and one of the fastest gaming monitors to get the most out of the mouse. That includes a beefy graphics card, which is especially important since it’s recommended you don’t use G-Sync or FreeSync with the mouse. Following the update to Test Bench 1.2, some of our test results have changed within both the Weight and CPI sections. We've added or modified some of the text in this article to clarify these changes. Oh, and just another side note. I know that I wrote a lot – but I’m a professional in the tech field, however, I really, really enjoy studying this stuff in my free time just for some fun (and being that I’m an avid gamer, all of my information is based upon things that I’ve discovered to be facts through my research). I just wanted to include that because nobody ever believes in what I write nowadays and they often state that it’s all lies and/or marketing crap…when the truth is, it isn’t lol. Of course, when it comes to input lag there are other factors at work besides the mouse's individual latency. The overall amount of time it takes for my mouse input to appear on screen not only depends on the mouse, but also how long my CPU and GPU take to process it, as well as the screen. I have decent specs here, but the lowest latency results possible would require something like a desktop RTX 3090, along with a 360 Hz monitor.
Great Deal
