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. For my first attempt I changed some BIOS configuration. I set the RAM settings to use the XMP profile.

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. Razer mentioned that the cable would be stiffer than what they normally use due to the need for extra shielding with the 8KHz technology, so I half expected some kind of dramatically stiff cable here but to my surprise this is all extremely tolerable. Don’t get me wrong: it’s not a great cable, but it’s definitely not the worst that I’ve tested in recent times either. Pop this one in a bungee and you won’t have any issues with it at all. If you’re used to wireless mice you’ll need a bit of time to adjust, but if you’re coming from an older wired mouse (or a recent one with a stiff cable) you probably won’t even feel a difference. Sensor and Everyday Performance

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: 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: 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? 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. Something that’s also noticeable is the fact that the Viper has comfort grooves in the main buttons that are rather pronounced. I like that kind of design so for me it’s a win, but if you dislike these sorts of things this might be important to know.

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. EU Declaration of Conformity for Abyssus Lite & Goliathus Mobile Construct Ed. Bundle (RZ83-0273).pdf 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.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. 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 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. 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. For a full explanation on my thoughts on 8KHz you’ll need to go the ‘performance and sensor’ section, but in short I’ll say: there are more important factors to a gaming mouse than the polling rate. Don’t get this one if you know you will dislike the shape, thinking that the 8KHz polling rate will catapult your aiming skills into the stratosphere. It won’t do that. But if you’re already used to the shape and you’ve got the system to match it might make you a bit more consistent.

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. 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. 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 Lightweight Design: Its agile form factor is extremely easy to handle and comes at no compromise to its build strength, allowing for deft control that feels like a natural extension of your hand so far, it's been about 2 weeks. this mouse is ultra light to me coming from a steelseries rival 600. the steelseries was slightly over 100 grams so it's almost 30 gram difference. this weighing in at 74. I didn't really expect it to affect my or even be noticeable. boy was I wrong. instantly lighter and the feet on this mouse glide so smoothly.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. 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. VSyncTester’s HTML/JavaScript mouse input performance benchmark looks at mouse latency. Again, this test is subject to how consistently I can move each mouse, but the Viper 8K Hz managed the best score, usually in the 3.30ms range. The DeathAdder V2 Mini and Burst Pro were both typically in the 3.40ms area, not far behind.
