pmw 3950 sensor always feel floaty

[mina]

i have tried a mouse with 3395 sensor it works fine really good and it go where i aim but when i bought a mouse with 3950 sensor it feels floaty and inconsistent i though it was a placebo but i found a reddit post that say the same things about pmw3950 sensor


is there any way to fix it , may be it is windows problem idk .

All the mice I have with this sensor had the Motion Sync setting hidden in the software so I was a bit shocked to find it only after weeks of usage. Other than that I cannot differentiate the sensors by feel.

I think it's the 8000hz polling. Set it to 2000hz - 1000hz, you'll be fine.

Why is 8000hz polling bad?
Your game gets your mouse position at the interval of your frame times. For me, my frame times are 7ms @ 144fps. During this 7ms gap, your mouse positions are accumulating waiting for the game to pick it up at the next frame time. Once that frame time comes, your game gets a burst of all this data that was accumulating between frame times. At 8000hz polling, that's a lot of positional updates. Some games can handle it some can't. You get that floatiness because the game can't process all those position updates fast enough.

8000hz polling is just a gimic, and offers no gains. Only really high end cpus can handle it. And not a lot of games are designed to handle that large burst of mouse positions.

Or it could be something else. But this is something a lot of people don't understand about the high hz mouses.

Edit: And some my say, well I have another 8000hz polling mouse that works fine but this one doesn't. So the reason why is, the designers probably tested thoroughly and saw this issue. So they most likely implemented some type of data smoothing or downsampling to minimize this high burst of data into their drivers/firmware.

got A7 Ultra
i set the mode to extreme, 2k polling rate , LOD 2mm
set everything to MSI mode
disable vsync

disabling VRR in Desktop

no inconsistencies

I have 3395 Mchose g3 Ultra 8k and it's perfect, zero float

Well, it's not just a gimmick, but rarely the games handle it correctly. So if a game feels floaty with it, try 1000 Hz.
If a game really supports 8000 Hz correctly, you definitely can feel it's crispier and smoother.

Motion Sync is crap, disable it if you can.

My OP1 8k v2 works wonderfully with the 3950 sensor.

Pretty sure what you’re feeling is mostly placebo. The reason is that 8000hz polling is overkill. At that rate the mouse picks up every tiny micro‑movement and finger twitching, which isn’t useful and can hurt smoothness and accuracy.

Because of that, a lot of mice and drivers/firmware downsample and smooth the data before it reaches the game, so you’re probably not seeing true 8000 Hz behavior anyway. It's most likely 4000–2000 Hz after preprocessing. And honestly, it may even be inaccurate because of the downsampling and data smoothing. Then there is the added delay from the preprocessing.

2000hz - 1000hz is more than enough. 8000 Hz is mostly a marketing gimmick with very limited real‑world gains. Literally no professional gamer uses it in a competitive setting. They might use an 8k mouse but they use it at 1000hz. Are the professionals wrong? They're better than you at being able to see if 8000hz actually makes a difference. But they still choose not to use it? I wonder why.

If your mouse firmware offers you the ability to actually use the mouse with raw 8000hz, try it, you'll probably hate it.

@soul4kills stop it, I have analyzed this in detail
there is a clear benefit to it if the game supports it cleanly

8 kHz might have issues with wireless, this is probably the top reason why pros don't use it

Also there is the issue with the games themselves. In Overwatch I already noticed worsening of input lag with 2 kHz, the game works best with 1 kHz. In Diabotical 8 kHz provides best performance though.

Unity games also don't support > 1kHz without introducing lag.

Do you know how games solve the problem. They buffer the reports. So you're not getting the raw input because it's too much for a game to handle. Imagine having to recalculate a scene at every raw input. It's extremely taxing on the cpu and gpu. It's a gimmick dude and you fell for it.

Weird thing is you are aware of the problems but you can't seem to make the connection to why it's pointless and it's just a gimmick. If you understood how computers work you would know. The problem with games aren't because they aren't "designed" for 8k. The problem is using 8k is stupid, the negatives implications out weight the 1ms advantage. If a game works for 8k, it's because it's simple and low complexity. When a game doesn't work for 8k, it's because of the high complexity of the game. A games fix, is to buffer high polling. They would never design a game to work with raw 8k inputs, because they know it's stupid.

Varlorant did this.

Edit: Here's a good read.

They are accurate in the negative implications of 8k polling, but then "their marketing" speak contradicts it. They even go on to say, "Is 8k right for you?" lol, if you believed in the technology and it's perceptible advantages, why would you even question it? Then they go on to suggest maybe 4k is better for you.

After I bought the Pulsar TenZ mouse and then the Pulsar Crazylight X2 I did a deep dive into this topic because of the floaty inconsistent feeling, also with the Razer Viper v2 Pro and DeathAdder v3 Pro I had the same-ish feeling, but it was a lot better on 1000hz dongle vs the 8000hz.

I have no issue on my 3395 sensor mice, Vaxee XE wireless, OP1 8K among a lot of other mice. (I used the OP1 8k at 8000hz btw)
