Some examples are the ‘Raw Input Buffer’ in Valorant and ‘High Precision Mouse Input’ in Overwatch. For transparency this is my first razer mouse, and only my 3rd mouse. fist was a cheap havit mouse that came with a bundle. second was a steelseries 600. Honestly I assumed I'd get this mouse and be underwhelmed.
the liftoff distance. this is the number one win for steelseries. they had a liftoff distance as low as .5 mm lift off distance which I absolutely loved. the lowest for this mouse is 2 mm. so lifting and lowering there is mouse jottering I'm not a fan of but overall not a big issue. big win for steelseries 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. We've converted this review to Test Bench 1.2. This update simplifies our Weight test and expands on our CPI test from Test Bench 1.1, resulting in changes to test results in both sections. For more details, you can see our complete changelog here. Some game engines, particularly in older titles, simply cannot handle high polling rate devices well, as they were never designed with such devices in mind. But additionally, the mouse is literally ambidextrous (identical on both sides) – so it’s the perfect product for a left-handed mouse user! I just got mine after having a Logitech G502 (non-ambidextrous mouse) for like….7 years…. And as a right-handed mouse user, I was pretty worried about the ambidextrous design. But after just two days of use, I can confirm that this mouse feels amazing! The only issue is that the buttons on your non-thumb side of the mouse are a bit difficult to reach – but that 8000hz polling rate makes it feel absolutely amazing so long as you computer is beefy enough to push your games at a high refresh rate. But anyway, being that you currently have a mouse that is extremely similar to my G502, you’d probably get adjusted to the Viper in a few days – just like I did.
Full Technical Specifications
The Razer Viper 8K Hz is a speed demon. Don't get me wrong; we're talking fractions of a second here, and most of us won't see a huge difference compared to previous editions. It isn't going to offer any benefit if you've got an older monitor, either. But it's a big deal for those who want to squeeze every last millisecond of speed from their gear. There's a reassuring feeling about your mouse being the fastest one out there, too. In conclusion I’d say that unless you’re a Viper (wired) user looking for a new mouse I wouldn’t recommend rushing out to the store to buy a new one. A lot of factors come into play when it comes to aiming, and unless your aim is already nearly perfect and you’re playing at the very highest of levels where every percentage point matters it’s not a massive game changer. Cool new technology? Yes. Would be good to have standard on every mouse in a couple of years? Also yes. Would I be able to tell which one is 8KHz and which one is 1KHz in a blind test? Probably not. Is it mandatory for competitive gamers? No. Razer Viper 8KHz Review – Conclusion With a polling rate of 8kHz in CSGO I had extreme stuttering. The game was lagging moving the mouse. The issue was even more extreme using a VOIP application (Teamspeak or Discord). We've added a link to the newly-reviewed HyperX Pulsefire Haste 2 in the Weight section of this review.
I remembered from my study about the IRQ interrupts. I started to read how the interrupts work in Windows 10. I learned about the Message_Signaled_Interrupts. With the tool MSI_util_v3 (thanks to this article message-signal-interrupts-yes-or-no) lists the IRQ number, the type and priority of our peripherals. I discovered that my graphic card and my audio card were using the same IRQ numbers (16). I set the graphic card to use the "msi" type of interrupts: 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. When I did this same action with the Viper 8K Hz, the points of the oval where I could see arrows seemingly shoulder-to-shoulder expanded. It still mostly occurred on the left and right sides but was starting to appear more into the top and bottom sides. 8,000 Hz was ultimately enabling my screen to show me more frequent updates of my pointer’s location. 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. 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.

That emphasis on peak performance is mirrored by the grips on each side. Made up of tiny rubber hexagons, they stop the mouse from flying out of your grip during a particularly intense match. On much the same note, the DPI button has been relegated to the device's underside in an attempt to avoid accidental presses.
To find that out I did a number of things: I of course used it as my main mouse during my testing, but I also went into a bunch of different programs (KovaaK’s, CS:GO training maps, Valorant’s training range, …) to compare it with the Razer Viper Ultimate that I have lying around. Considering the fact that shape, weight, and so on are also very important for performance I found it best to compare it to another mouse with the same shape instead of any random mouse (or my main mouse). I did some ‘scientific’ testing in the games that I used (where I compared how many targets I hit within a certain timeframe, or how long it took me to kill X targets, or just my test scores) and found that I indeed performed better with the 8KHz. After all was said and done I did around 2% better with the 8KHz compared to the Viper Ultimate, when I counted all of my tests together. Bear in mind that none of this was very scientific, so of course I also used it for normal games and deathmatches. 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. For my first attempt I changed some BIOS configuration. I set the RAM settings to use the XMP profile. After a restart to apply this change, I did a new the Polling Rate test with the mouse configured in 8kHz, the results are perfect now: We've added a link to the newly-reviewed Razer Viper Mini Signature Edition in the Sensor Specifications section of this review.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. Razer sees the increased polling rate as bringing a greater advantage in gaming, specifically around improving aim and synced-up shots. And that advantage is perceived as being greater than what a higher CPI spec provides, which Razer admits may not yield usable advantages.
In addition to beefier specs, the Focus+ also has some high-end features. But to be honest, there’s a good chance you’ll never notice them. One very important caveat is that you need some decently beefy gear to reap the rewards: the 8Khz polling rate will make your PC work harder and unless you’re gaming on a high refresh rate monitor the advantages of the high polling rate will not be tangible at all. There’s also the fact that not all games support this kind of polling rate, so you might not get the full benefit from this tech for quite a while. Consider it an early adopter tax. 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. Note: I have to configure the graphic card to use the MSI type of interrupts after every update of the NVIDIA drivers That 8,000Hz polling rate makes a tremendous difference in-game, too. Weapon movement is noticeably crisper in the likes of Apex Legends, and this allowed me to pull off precision shots with much more ease. I actually set up a 1K Hz mouse alongside the 8K, and it felt weirdly choppy by comparison. It was still fine in the grand scheme of things, but I only realized how much cursor stutter affects performance when I was hopping from one device to the other. It feels as if you're fighting with those older mice, whereas the 8K removes barriers you may not have realized were there in the first place.

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?
