High CPU usage when moving mouse?
Hey, first i will say that I'm from Denmark, so there might be some wrong words and so.

My problem is that my CPU usage is going high every time, i move my mouse. Right now i run 28 %, but when i then move my mouse it goes to 65 %.

My mouse is a Razer Deathadder 3.5G and I'm running it at 2000 DPI with Razer Synapse 2.0.
I think the problem with the CPU usage is either Razer Synapse or my hardware.

I can use my Deathadder without Synapse, but it will reset the DPI and the 2 buttons on it. So i can't use them. I have the two buttons to (K) and (G). And i need those to gaming.

I have check the drivers and can't find one, there isn't up-to-date. I have used Ccleaner, Malware Bytes, Avast, Rkill and so on. None of them is showing a malware, if it's the problem.

Specs: (Pakard bell easynote tk11bz
AMD Dual-Core E350
AMD Radeon HD6310
500 GB
2 GB DDR3 ram (getting the last 4 GB in a week or so.)
Windows 7 4 bit

Anyone know what i can do to dis crease CPU usage, when moving my mouse around? And plese reply in steps, so i can understand it better :)

Hey, I use Razer too for my setup I had these problem sometimes too. I just close and reload the Synapse program and CPU usage reverts to default.

Hey. I finally managed to find a relevant thread to this issue.

Same thing happened to me recently: my PC was going nuts, not even being able to move the mouse properly, task manager taking forever to start, folders not opening and such. It'd take for 1-5 minutes to "cool down". I found out that System CPU usage was around 30% but never thought it could be Razer Synapse or my mouse (since I also am using a Deathadder 3.5G).

Next time it happens, I'll try to uninstall it and see if there's a change. My CPU never went beyond 10% even when playing Crysis 3 on full details (see specs). I'm also trying to root out any malware so I'll see how that goes.

Specs: ASUS G750JX-T4179
Intel Core i7 Haswell 4700HQ (2,40 GHz)
GEFORCE 770M GTX (3GB)
16 GB RAM DDR3
SSD 64 + 750GB 7200RPM
Win 8.1

clayofthe757: Now the CPU usage is lower. Which synapse verison should i then install?



I'm not familiar with the make. Try older drivers/software if you have the option.

Still, I wish you luck.


I just wana say that the problem is fixed for now. I installed the lastest driver version (3.05) beore Razer Synapse came out. It's working fine and my CPU usage isn't going mad every time i move the mouse. Thanks for the help.


You're very welcome. Choose my answer as the solution if you think it is appropriate.

There isn't any reason that mouse should bog your processor. I recommend removing all software associated with the device and reboot. At that point DPI settings and button usage may be skewed or not functional, but don't worry about it yet. Watch your CPU load as you use it as a 'Generic USB Pointer Device'. If the overuse disappears with the software, then you know instantly that it was the software that was the problem. At that point you can try installing whatever version of the software you can find for. You may need to use older software to accommodate the age of the machine.

Best of luck.


ok, i will try that and come with a result.

You could check in task manager which programs take up a lot of calculating power and consider turning them off/deleting them.


When I'm surfing on the internet, there is only the "maxthon 3" procceses opened.

When i game i think its Svchost. Yesterday when i played css, fps falled to 13 fps and svchost was using 70% CPU. Never happend before.

I know when i'm browseing that maxthon uses some CPU, but gets only high when moveing mouse or multiple tabs.

''High CPU usage when moving mouse?''

thats normal for me
if you want ? you can check by the task manager if you have a killer software running..
and take all the juice of the pc... who know?
