High CPU usage when moving mouse

[Texeon]

Hello!

 

I have recentley noticed my mouse uses up a lot of my CPU when moving it.

The CPU usage jumps from 30% to 50% when i move the mouse.

 

I thought it might be a Virus/Malware Issue so i went step by step through this guide to possible remove any Viruses or Malware.

I have also tried uninstalling my drivers of the mouse and letting windows update get the latest version.

I had to get the drivers using windows update because on the manufacturers website there are no drivers for my mouse.

When using Winexp and moving my mouse on my desktop explorer.exe was jumping in CPU usage (up to 50%).

But when moving my mouse in Mozilla Firefox my cpu usage was only between 7%-11% CPU usage.

 

Thank You!

Why are you so concerned about it, that should be typical. What is your processor?

[NicekillBG]

dont overclock your mouse

[MegaDave91]

Normal

My cpu usage was never this high when moving my mouse.

My processor is FX-4100 Quadcore Processor

 

 

dont overclock your mouse

 

 

Not Overclocked

 

EDIT: i dont even know if that is possible

CPUs do what they're told. Moving a mouse is essentially giving it a constant stream of information to decode and interpret as movement of the cursor on a screen. Rendering by instruction is much harder than just displaying images. What you're seeing is simply the CPU ramping up to deal with the unpredictability of your actions.

are you using extreme DPIs, that then are scaled down in windows mouse settings?

thank you for the explanation, i was only worried because that was never happening before.

 

Sorry for bothering.

although it seems kind of extreme to be displayed as a 20% increase in CPU load

this would mean that playing a game with a Dpad and 4 buttons, would save 20% off your CPUs load, which i dont think is true

maybe its just the CPU getting too excited, hah

No my mouse is running at 800 dpi atm (lowest possible on my mouse).

and i have never changed the mouse settings in Control Panel before.

Understand that he's running an FX4100, a CPU not renowned for its single-threaded performance. Mouse movements are entirely single-threaded, so one of those threads is operating at 30-50%. You'd be surprised at how complicated calculating mouse inputs and interpreting them to a graphics controller is, especially at 1KHz polling rates.

tried this on my own, and i managed to get the CPU to boost clock all the way to the highest possible speed without overclocking

i managed to get my intel i5 4690K to go from 3% to 27% though

if laptops can gain 20% more CPU speed, just by using a controller, then why would it be so unheard of

 

 

edit: tried 6500 DPI, and it didnt make a difference, but i must say, windows has a really optimized mouse, where if it slamms into the screen wall, it ignores mouse imput, untill it starts to go a way it can go

[Texeon]

I went to check my Mouse options in Control panel and disabled "Enhance Pointer Precision" and it lowered my cpu usage on my desktop from 50% to 25% on mouse movement

It would be easier if it were running at an on-off set speed, but if you plan on having analogue control then it'll still take resources. Mice give you more precise control over the cursor at greater speeds with greater responsiveness and accuracy. It's why instances where console gamers and PC gamers can play the same game with each other end up very one-sided. To maintain accuracy with a d-pad or analogue stick it would have to be painfully slow. Imagine trying to highlight text with a d-pad! Perish the thought, i say.

It's not like your CPU is suffering or anything. It really doesn't matter half as much as it seems. a 386 can manage it, so can OP's 4100.

What's the polling rate of your mouse? I know a lot of gaming mices have ~1000hz polling rate which may be taxing for some computers.

where can i check that?

[TroubleKlef]

check your mouse specs.

[Texeon]

check your mouse specs.

 

the only 2 specifications there are is that i need a USB port and windows10/8/7/Vista

sounds like a pretty basic mouse then. The polling rate probably isn't the issue then.

[monaka25]

Restart your PC?

[Texeon]

Restart your PC?

 

did that twice

[Texeon]

Oh and i have 1 more question (since i dont really want to make another thread for that).

 

Why does it show i only have 2 cores in Winexp, Task manager and CPU-Z?

im not talking about me switching to a dpad while playing CS, dont get paranoid just because i mentioned a dpad being superior to the mouse in one way, but im talking about people on laptops playing emulators (yes you can actually use the mouse in some shooter arcade games), 2.5D sidescrollers, such as trine 3, and maybe even warthunder aerial battles, if they would earn 20% CPU power by not using a mouse, then wouldnt it be a known thing to do, like disabling the transparent theme in windows 7+

that happened to me too, when i had my old intel sandybridge CPU

Pages on the internet said it has 4 cores, but all the stuff that i donwloaded said it had 2 cores

 

Im still not sure to this day, it shall remain a mystery

 

edit : fixed graphic card into CPU
