My grandson said he is “cracked” after I show him this video. I think that is good. Newly subscriber!!! Thank you!!!

The amount effort put into this video is crazy. The combination of relevant PC/gaming information and god tier cinematography is unmatched! 👏👏

not sure if it's been mentioned here but some sensors interpolate between samples for their higher DPI giving you a more noisy output that isn't as accurate and drifts (not that much but it's still something) with some sensors actually getting interpolation turned on at as little as anything above 1600 dpi. basically it pays to check your specific sensor and see what its max dpi is before it starts running interpolation and use that. or alternatively, pick what feels best in windows at medium sensitivity (6/11 setting in windows) and call it a day (never change windows sens value, if nothing's changed since the early days then changing that setting introduces even more artifacts that you don't want to deal with). also some mice run better at 500hz and struggle to run 1000hz and give you inconsistent reporting. you can download a mouse polling rate checker and move your mouse around quickly and see if you get 990-1000hz reporting or if it bounces between 638hz 782hz 598hz 802hz 712hz etc. for really consistently fast movement - probably just stick to 500hz if you see that. (if you move your mouse really slowly it can do that too though just be aware) and not to mention some CPUs actually can get slowed down a bit with 1000hz polling during an intensive game. my old CPU used to actually have noticeable skips in gameplay at 1000hz polling rate, just be aware of that

Man this is some serious research. Super impressed with the extent they you've gone for this. Awesome!

This is next level tech reviews... builds his own machines, writes his own code, and all that delivered in such a good way without any obnoxious screaming and weird facial expressions

I have to say; I've watched several videos on the same topic, but this is BY FAR the first one that was digestible. a.k.a. NOW I understand.

Would have been really neat to see the most popular mice tested. Also with the DPI tested up to much higher amounts. Perhaps a part 2?

This is absolutely wild data. Thanks!

Absolutely love the tests in this series, looking forward to the next one! Now to find a wireless mouse with a shape I actually like...

Dude! You're being very modest. It's not a pasta salad that you whipped up over there but an awesome measurement device. RESPECT!

You could also test acceleration of the sensor :) fast move right, slow move back left and the cursor should be at the same startingpoint.

Awesome video, it's really good to know dpi effects latency that much. I'd like to see you test more mice on this, and kinda come up with a top ten low latency wireless mice or something like that.

not many creators i'll stop what i'm doing to watch, but yours is definitely one of them

The thing about turning down in game sensitivity and increasing it on the mouse, as well as DPI, was something I totally found out by accident. Thanks for explaining all of this in a way that's easy to understand and for an overall fascinating video

Good job man, I'll be watching your future videos with these tests for sure. And I've learned it's better to use high DPI with lower sensitivity, will test this out now :)

I REALLY want to the see the next set of tests. Mouse acceleration etc. I don’t see anyone else using something well designed like this. Very cool. And thank god for putting some rest to “wireless will never compete with wired”

This is top tier content. So many unscientific videos exist on mouse DPI where someone is dragging a mouse by hand. I would love to see the raw data in some kind of spreadsheet format but otherwise nice work!

Seriously everytime I watch his channel, I get more and more impressed by his cinematography, his PC building and his engineering skills Ali, you rock!!

I’d be interested in where the line is between physical DPI of the sensor and the interpolation used to reach higher DPI specs. For example, the actual sensor resolution might be 800DPI while interpolation allows it to figure out up to 3200DPI.

May I just say, you're the most meticulous tester that i've found and that explains everything in such an easy manner. I also love the fact that you mention to be a gamer and play a lot of shooters and what not, so it's like good that I can relate more and I can understand things more. You're awesome :)

The level of analysis, depth and just sheer engineering here is god tier

Really impressed with how you built together the test rig. It reminds me of the many creative ideas the 3D printing community comes up with.

the b roll shot at 1:21 of the mouse and the test machine you built is s-tier. just had to show some appreciation for that. GG

I'll try and do some controlled testing of my own, but from personal experience of playing at 3200 DPI for 8ish years, switching to 400 DPI 2 years ago might as well have been magic with how much it improved my gameplay. Yes in sterile testing higher DPI looks like a straight up improvement. But the reality is that humans are....human. Higher DPI means you're more prone to micromovements and jitters affecting your aim more. If you're a professional level gamer, higher DPI might be more beneficial, but for even above average gamers it really isn't helping. When my friends stream their games, we can easily tell if their DPI is too high by how twitchy their mouse movements are. We've convinced nearly all of our friends to drop their DPI to the 400-500 range and every single person has noticeably improved their ability to click targets.

The effort OT put into this video is insane. And bonus points for including standard deviation! :D

Impressive! 5/5 cookies for your amazing work 🍪🍪🍪🍪🍪

I feel we are missing an insight here? If we imagine that DPI is the amount of squares on a chessboard, and we use that chessboard as a mouse mat. Each square is a signal of movement from the mouse. So the higher DPI, the more squares on the chessboard. If we now drag our mouse across the chessboard - the smaller the squares, the faster the initial response of movement would be. But would higher DPI really reach its target faster?

This and the PBO2 video is why I became a sub. I never thought that high DPI and low sensitivity would be a better way to go. And yeah, the Superlight is such a great mouse and the PowerPlay charging mat is so worth it. Being an old timer when we were lucky to have side buttons, the two side buttons of this mouse are great. The G502 I had before was just too heavy and to many miss-placed buttons.

Thank you for such a good contribution to the mouse community! Although I saw no one wondering, I wonder if the mousepad’s micro-texture plays a role when it comes to accuracy at higher CPI. If I understood it correctly, higher CPI means that there’s less distance between each counts on the surface(mousepad). While Mouse sensor’s development is clearly going on, I wonder if mousepad’s surface are truly able to support high CPIs. If they're not, I think that explains why there are some people who believe that they feel better and more accurate/consistent at 800 CPI than 1600 CPI. Well it’s fair to point out that it might be because that’s what they got used to, but I think looking into relationship between mousepad’s micro-texture and higher CPI is an interesting topic. ...or I’m just a stupid monke. Thank you for reading.

Keep these tests coming, the average customer (even though technically he wouldn't care too much) has a right to know about these things. Sensor latency and click latency tests have been somewhat neglected and I'm happy you're one of the few people that is putting it out there.

Amazing test! Very useful. One thing to consider is that FPS games where you typically do horizontal moves benefit from lower DPI, since your mouse has less vertical pixels to distract it when doing a horizontal move. Basically at lower DPI the movement is more straight or linear. At higher DPI it's more precise but this means your mistakes at doing straight lines are more pronounced.

The problem I have with 1600 DPI is many games don’t let their in game sens go low enough for my taste so I pretty much have to use 800 so my effective sensitivity is as low as I want it to be.

Ali is on a breakthrough here. This will take him on the top of the chain when it comes to reliable subjective AND objective takes on mouse. It's great to see how much this channel and Ali has improved over the years.

thank you so much for doing the test, seriously!! ichange my settings from 2 sens 400 dpi to 0.375 sens 1600 dpi (which is 1.5 sens with 400 dpi), and my new "1.5 sens" is so smooth and feels like im playing at 2 sens. Keep up the good work man!!!

I'm late to the party here, but it doesn't look like you adjusted speed to hit an expected distance based on the current dpi. When using a low dpi, you have to move the mouse further to achieve the same onscreen effect. If you hold the motor speed constant across the tests, I'd expect to see a delay in the onscreen effect even if the sensor & mouse performed identically because the OS is delaying the time to first onscreen cursor movement until you reach a mouse position (which is further for lower dpi). Additionally holding the motor speed constant doesn't seem like it's relevant because all of a low dpi player's mouse movements will be appropriately larger, and thus trigger the threshold sooner. I suspect your slow graph is showing this pretty distinctly. If you assume from the 3200 dpi case that the mouse has a sensor latency of ~17ms & movement delay to reach the target mouse position of about 1.5ms, it extrapolates nicely to most of the rest (1600 dpi takes twice as long at 3ms, 800 again doubles to 6ms, 400 doubles again to just under 12ms, and 100 dpi registers at 40ms [I'd expect a 48ms movement delay from the pattern, but this data point has a larger error bar]). Anyway, I'd be really interested to see results if you double the motor as you halve the dpi. I'd also be very interested to see some results when using the raw input windows mouse api instead of the standard OS cursor. That should give the test a lot more precision and fidelity as it shouldn't be snapping to distinct pixels. Games are hopefully using raw input for the most part anyway. I gotta say, I love the video even if the testing methodology needs maybe a bit of tweaking here and there.

Very informative and interesting video. I hadn't thought of using higher DPI settings with lower sensitivity settings in the game. Thanks for this!

RocketJumpNinja: Well I'm Retiring to make my own mouse Optimum Tech: It's Free Real Estate

You have to be my favorite KZfaqr. The information you present is always clear, concise, more creative and in depth than most other youtubers or even just trying to read up on information via forums. The amount of knowledge I feel I have gained just from watching your videos is enormous considering I am not even watching to gain knowledge but to just be entertained. So being able to consistently do both you definitely deserve praise.

This is test set up is amazing, I have never seen any other big reviewers go to this extent to build and program their own equipment for testing mice!

Great video and testing procedure. You should do the same thing for keyboard, like checking input lag of custom keyboards and off the shelf ones.

I started using 1600dpi as opposed to 800dpi back in 2016, havent looked back, when you play with high framerates you can feel and see the difference quite a bit more

I see that Bones Reds bearing 👀 Really cool machine you built.

I've tried higher DPI and I found it so much harder to move the the mouse in a perfectly straight line. Pretty much confirmed when I tried making a straight line in MS paint.

This is the most underrated tech channel. Not only is the cinematography just god-level, he's also doing hard core science.

I'm legitimately curious to see what the latency would be when cranked to like 16,000 DPI. I know diminishing returns and all, but still. Would be cool to see! Anyway, awesome video and really informative! Gonna experiment with turning my DPI up a bit and lowering in-game sens and see how it goes.

Man, you always come up with content that everybody wanted but nobody made before. The effort you put into your videos, the topic choice relevancy, and production quality in general, make you my favorite overall content creator. Keep up!

The thing is if you crank up the mouse's DPI setting, navigating the settings and menu outside of the main game would be a pain. It's not like the mouse's software can determine whether you're in "crosshair mode" or "cursor mode".

You did a good job building that tester. even looks well made like it was engeneered and manufactured. after lots of messin', I settled on 1600 and turn down in-game sens.

Epic that you made your own kit to test this, really adds validity to what you say.

My man Ali deadass built a modern futuristic engineering type of shit to tell which mouse us faster in ms Really a legend

I did that for close to a decade. Running at native DPI but lowering the in-game multiplier makes for a small but very noticeable difference in smoothness

As for me having thousands of hours spent in FPS, I wish I'd be able to switch from 400 to 800 DPI after your professional testing. The sad truth is, a lot of games don't offer fine enough adjustments or even low enough sensitivity values for me to consistently being able to use 800 DPI on all of them.

Unfortunately there's still quite some games that'll require you to have like 0.00142 sensitivity if you're planning to play on a low sens with high DPI.

After i saw a video from the battlenonsense channel a few months ago, i changed my dpi from 800 to 1600 and have noticed a big difference since then, the response time is noticeable and you can get a lot better accuracy.

I have to question the results of the DPI test, if the sensitivity of your mouse pointer was too low you could effectively move the mouse a small amount without the cursors position moving a full pixel. This is something that is specific to using a mouse pointer and does not reflect the way that aiming in FPS games works.

1600 DPI from my experience with the superlight pro x is just perfect. was using 800 because thats what i always used. bumped it to 1600 after watching flats in overwatch and he said thats what he used (same mouse as me) and literally just increased my accuracy by so much

Yk isa good day when Ali uploads a video

Man, great video. Two weeks ago a changed my DPI from 800 to 1600 and the sensitivity in valorant from 0.4 to 0.2 because I thought the input delay might be lower that way, and I was right! Your video is gold!

I've been looking for this information for so long never found anything, today it just popped up on my feed, youtube is very weird! Thanks for the information! Very useful!

good stuff !!! Nice methodical testing, and supberb vid and sound quality, a pleasure to watch.

Btw your thumbnails are completely insane

Awesome video.The effort and thinking behind the testing needs to be appreciated more and got you a sub. I've always wondered if attaining the same eDPI with different mouse DPIs made a difference.

Have you tried 25600 DPI with the GPro wireless?

You should measure the latency up to the maximum supported by the mouse and check whenever too high actually becomes bad. Otherwise why not just max the mouse dpi and lower in-game sensitivity.

"Why Gamers are Switching to High DPI" Me who started high DPI "Welcome, to paradise"

Very creative and informative video. Nice

really awesome in depth testing!! i've always been curious about these topics, damn nice to finally see some statistics! advanced tool-testing that reminds me of gamers-nexus style, keep it up guys! :)

I think 1600 is the sweet spot, above that there is a lot of small inputs you can't do as a modeler I need extremely precise movements, maybe it is just me but at least it is a valid point.

This was already known back in 2008, that is why i went from 400 dpi to 800 in quake. Plus tracking is far superior on higher dpi, less pixel skipping.

Great job testing and rating the mice. Love your style of presentation of data and results without shenanigan and unnecessary jargon. A true no nonsense style of testing.

i have been playing on 800 dpi for 4 years now but have just swapped recently to 1600 dpi because of this video and haven't swapped back in the past 4 months, feels so much greater i recommend everyone to do the same

Taimou gave me this info years ago I'm surprised more people dont know this. Good work on the effort behind this though which is nuts

Crazy how I myself as a gamer and a software/hardware engineer have never thought of this. Now that I think of that, Higher DPI +lower multiplier works like supersampling and lower DPI + higher multiplier is kind of like up sampling. I will definitely try doubling my DPI, although I doubt it would be able save my poor aim.

I’ve been trying to explain this for a while. Finally, someone who can do it. Thank you

Excellent work. I'd be curious to see what kind of difference 8k polling vs 1k polling would make at 1600 and 3200 dpi since the gap is already so close.

holyyyyyyyyyyy, i play rainbow six siege so every milisecond counts in a gunfight, i changed my sens from 12 to 1, dpi from 400 to 4800 and a huge improvment to my reaction time and gunskill, not just that but its much smoother and less skippy, going from a sens to a lower sens is just math, so say you use 10 sens 400 dpi, go to 4000 dpi at 1 sens, with sens's like 11 or 7(odd numbers) then for the 7 sens go from 400 dpi to 2800, the math is simple. you take your dpi and multiply it by 2, then youd have to cut your ingame sens in half to match you previous muscle memory but you keep doing so till you get one, it does get tricky so i found an easier way, say for 7 sens, 400x2=800 which would give us 3.5, you cant use 3.5 anyway but, then you take 800 dpi and mulyiplier it by that factor(3.5) giving us 2800, you can do this for any sens, works best with mice that have an app where you can use dpi's like 150 or 8550 by user choice in settings, i hope i helped at least one person get better, LOVE YALL

This 1 man channel, just out researched LTT and GN

Really thanks for those tests! It was interesting to watch, and especially thanks for the last lifehack to turn DPI up and game sens down. Your testing equipment is shocking. Great job!

I noticed that my wireless mouse (Viper Ultimate) is very sensitive to the level of battery charge. My Kovaaks scores clearly reflect this, I belive this is related to the polling rate that actually changes according to the battery level. I'd love to see this tested with this clarity, it would be an argument in favor of wired mice that I never heard about.

I've been playing forever on high dpi (2000) and lowering in game by a lot, so I actually play low sens but high dpi I would never know this was a beneficial thing for me.

Really great job done here letting the machines do the tests, I had in mind that higher dpi should work better but I didn't know how to measure, thank you a lot!

Really great tests, would love to see how different sensors perform on different mousepads/surfaces now

I have always tuned my mouse to about 1.3k dpi and lowered ingame sensitivity, idk why but just felt like the right way to do it (mostly because i prefer higher sens outside games)

Can you do a video about the gaming mouse scroll issue that has always been there and can't be fixed, how to prevent or never have the issue? New mice always start having the issue 3 to 4 months into using it. (v3 pro/superlight g pro)

Great video, but why not test the Razer Viper 8K Hz? It has arguably the best sensor on the market and the fastest polling rate. It would definitely be interesting to see the results.

Absolute dope! The effort you put on your videos is commendable.

Awesome vid, love these kinda in-depth analysis.

super super super cool test setup, looking forward to more. subscribed

Not sure if you could call it latency actually in dpi testing - you need to cover more distance to register event in lower dpi vs higher. It's like measuring the time it takes to cover keystroke length in the keyboard before actual switch signal goes from it. If one keyboard has long keystroke and another is based on touch interface but you start to measure time when you touch it then it's not latency I believe?

Love the combination of tech, programming, and 3d printing. Very well done as usual.

I rewatch every mouse video. Thanks for all the info / testing.

Great tool! And also great test results! I'm gonna implement this in my setup! Thank you!

Really cool test, wish more of yt was like this. Can't wait to see new one!

wow dunno how you pulled this off, impressive engineering.

So for those saying 8khz polling rate mice are a gimmick, this literally justifies 8khz. Definitely going to enjoy my Viper 8khz set to 2khz, but they need to make a Basilisk lighter weight and 8khz polling rate, it should sell hot.

Nice insane quality videos, as expected from you king!

High DPI + Low Mouse Sensitivity in game settings really boost my gaming experience

wow! I didn't expect this kind of deep analysis from this channel! Excellent work with building that kind of testing setup!

if my sense is 2.2 in apex @ 800 DPI youd actually recomend 0.5 @ 1600 dpi?

I'm absolutely in love with your content. All of your data would be enough to write a bachelors thesis and you do it "just" for informational purposes and your youtube account.
