Razer Viper V3 Pro

[pzogel]

Aside from the bringing the shape of the Viper V3 Hyperspeed to the Pro series, the 54 g Viper V3 Pro also debuts Razer's latest Focus Pro 35K Gen-2 sensor, and includes the 8K wireless dongle by default. The main buttons are still outfitted with Razer's Optical Switches Gen-3, and up to 95 hours of battery life are cited.

I'm sorry but we are at a point where I think with those prices and a lot of brands having all their mice with 0% sensor deviation, a 4% is not a good result, much less for a mouse of this price and brand.

4% deviation means that a 30cm flick for a 180º is now 28.8cm, someone could say that is just 1.2cm, but that 1.2 compared to a flawless mouse is a lot and can mess your aim for weeks on fast games like quake champions, apex or so.

0% deviation should be the only expected result, and razer have mice with 0%, so at least for me on their 160€ flagship having a 4% is not acceptable.

0% deviation should be the only expected result.

For clarification, deviation only means that when setting the mouse to 400 CPI, a mouse with +10% deviation will actually be set to 440 CPI. It is not to be confused with speed-related accuracy variance (or acceleration), where the cursor indeed does not end up where it should.

To give an example, on a mouse with very low SRAV (such as the Viper V3 Pro), a sensitivity of 2 at 400 CPI and a sensitivity of 1.82 at 440 CPI will both result in a 52 cm/360 turn circumference in CS 2, so when doing a 30 cm flick, they'll end up in the exact same position. CPI deviation merely requires some adjustment (either of sensitivity or CPI itself) when switching from a different mouse.

@pzogel
Since this came up - a question. Well, two.
1. How likely is CPI deviation to vary sample to sample?
2. Is CPI deviation surface dependent? I don’t remember if you mentioned it, but is there a pad you are consistently using for testing or is that irrelevant?

1. There will be some minor variance (1-2%) depending on manufacturing tolerances.
2. Absolutely, both between types of surface (cloth, glass, plastic, etc.) and different models of the same surface. I'm using a generic black cloth pad to be as representative as possible, but non-cloth surfaces in particular will behave differently.

@pzogel - I'm not sure if it was intentional or not, as the mice in question are somewhat similar, but the comparison shots use the Razer Viper V3, not the Razer Viper V3 Pro.

In my experience it is, though to some extent (certainly with Logitech) I've found that the software calibration for mouse surfaces offsets this somewhat.

I prefer to use microfibre cloth mats for that little added friction but tend not to pack one for events where I'm travelling light. My sensitivity feels lower on hard surfaces than it does on cloth mats, not by much, but at 800cpi I'm changing my sensitivity from 8.3 to 9 to get it to feel right on 180 flicks again. I'm old and slow now but I was nailing headshots at the end of a 180 degree flick 28 years ago and I'm kept my cm/360 as close to consistent for muscle memory as possible during all those years and all those mice.

The fact that I can feel something's off by only 8% and I wouldn't call myself anything resembling a pro means that a mouse with a CPI deviation of even 5% is likely unacceptable for something labelled "pro" and especially at this price point.

Yes, but we can know that because of your review, but what about a new firmware? will maybe change it? what about people not reading your review? they will end with a changed sensitivity, and at least me, I can tell a 5% deviation will feel odd. For example, I tried the razer cobra and it was awful with the sens, I ended returning it to amazon way before I could see why on your review.

and also, I do not think you should be adjusting your sensitivity in every game because the sensor changes between one mouse or another

There are people (few, but there are) with multiple mice on the desktop or setup for laptop/desktop. I for example have 3, a naga v2 pro, an hsk pro, and a logitech vertical mice, and I don't think it's acceptable to expect from me to mess sensitivity from every game and lose my time calculating it if I use one or the other, much less in a mice of that price

That's why I think we are at a point where a sensor deviation, even a 1% is not a good result. If perfect results can be achieved by dozens of mice on the market, then there's no reason of why a flagship of 160€ cannot and see it as a good result. For me it isn't in the slightest.

But I guess is just a matter of wording,

Ludicrous what one has to pay for peripherals these days.

I am still waiting for the Razer 2012 Mamba reboot, love the DPi button position on that mouse and the feel is perfect for my hand size, just needs to be lighter.

Intentional, allowed me to save precious time. The shapes are the same anyway.

This, I agree with - I use three different systems for gaming with a Razer Basilisk V3 Pro, a Roccat Burst Core, and a Zowie S2. Very different mice but I want 800cpi to be 800cpi because my game configs are saved in the cloud and cross-system, so the sensitivity shouldn't be changed per-game.

There's another reason it matters, especially for these expensive mice with a "Pro" label and sticker price: eSports tournaments these days often provide the mice - I believe the reason is because at the highest tiers with the most to play for, cheaters were discovered cheating (aim-assist and wallhack-to-headset audio cues) by having the hack payload delivered by their mouse USB connector.

If a pro-level gamer is competing in a tournament with a $25million prize pool, they're not going to want a mouse that's 10% out on their accuracy!

Yep, as expected with the DPI deviation - took me a while to adjust to the new sensor.
Can't wait for the DA v3 Hyperspeed review, btw!
