What's a good DPI for a mouse?

[Braiboo99]

I just bought a new Corsair gaming mouse and trying to work out what is a suitable DPI, any tips?

when a display is higher refresh than 500hz, let me know

What does the display have to do with the mouse (or keyboard) polling rate? those are separate and are both additive sources to input lag.

I was going to ask that myself but thought it would be easier just to post the monitors instead as I believe they are trying to make it sound like I know nothing as they posted else where as well but hey I'm always down to learn new things and have myself corrected if I'm wrong especially when it comes to PC's as you never know when the information you've learned will come in handy.

What's the point in that, to gain more movement accuracy?

speed, so you can 360 a dozen times before noscope

But on high sens it's much easier to miss the target :)

reaction time is much higher than that anyway
granted the more often it samples the position, it can have fresher data to use when creating the next frame
above 500hz makes little difference

Personal preference. I used to use 500dpi, I now have my mouse set to 1200dpi and just adjust in game sensitivity until I'm comfortable with it. The genres you play also factor in.

Are you talking about display refresh rate? or input device polling rate?

There is nothing wrong with using a mouse with a 500 hz or even with a lower polling rate if you are just using your computer for searching the web etc then the mouse will work fine.

However if you are gaming then the higher the polling rate the better it is and it will certainly make a difference as it will report back to your computer more frequently allowing for a smoother experience.

A mouse with a polling rate of 500 Hz has a response time of 2 ms, while a mouse with 1000 Hz polling rate has a response time of 1 ms and 2000 Hz polling rate has a 0.5 ms response time. So my mouse with 2000 Hz reports to the computer four times more than a mouse with 500 Hz. It is recommended to have a mouse with at least a 1000 Hz polling rate for gaming.

You can use a mouse with a pooling rate of 4000 Hz, however, if the game is CPU bound, then the experience shouldn't be better.

Then I would say that your CPU is not good enough to get the best out of your mouse if you are CPU bound in games. An Intel i5 9th Gen or AMD Ryzen 5 2nd Gen or equivalent CPU is recommended to get the best performance out of a 4000 Hz polling rate mouse.

You could lower the polling rate down to 2000 or even 1000 Hz if you do suffer any problems and it should work perfectly fine but then you have to ask yourself, what's the point of buying a high polling rate mouse for gaming if you cannot make use of it.

I don't worry about these things because I don't get CPU bound in games (at the moment) and my PC could run a 8000 Hz mouse so I have a great gaming experience.

I use 3600. That means I can go from one corner of my screen to the other in just a few inches of travel with the mouse. Aiming is extremely fast but tracking is a little more difficult.
I think I am pretty rare. Most people seem to use a much lower dpi and move their mouse around a lot more than I do.

Not how it works at all.

(The above diagram is from the NVIDIA LDAT documentation on measuring total system latency)

end-to-end total system latency (e.g. "click to photon", or in other words the total time it takes from when you "click" and actuate the switch on your input device to when the first "photon" change occurs, e.g. pixel changes on your display) encompasses more than just one thing; and each of those different things are independently additive to the total system latency.

Referencing the above diagram; The USB peripheral polling rate will impact both the "peripheral latency" and the first block, USB SW (Software) in the CPU (OS/Game) portion of "PC Latency".

This is, again, additive to the other things that you guys are talking about; which would be those "game latency", "render latency", and "display latency". As Piston Smashed™ noted a 500Hz polling rate will add 2ms of input latency to whatever other latency is being induced by your CPU, game, GPU renderer & compositing, and your display. None of those other things will impact or change that additional 2ms of latency from your mouse/keyboard. Whereas a 1000Hz polling rate will only add 1ms of additional latency; and a 2000Hz polling rate on newer mice/keyboards will only add 0.5ms of additional latency.

A game being "CPU bound" wouldn't change the peripheral latency at all. It would extend / add latency to the "game latency"; specifically in the "render submission". The relationship between those portions of total system latency, game latency and render latency, is what the gpubusy metric in Intel's PresentMon exposes so you can see the balance between game latency (being impacted by your CPU) and render latency (by how busy your GPU is being kept).

How funny

It's pretty much entirely personal preference. I set my mouse's DPI something like 8 years ago, and have since completely forgot what it is even set to. You'll be changing the sensitivity in games anyways, so it doesn't really matter much. DPI will just affect the scaling of sensitivity.
