On some occasions of computer usage, my mouse acts very strangely. Whenever my computer is under intense network usage (i.e. watching an online video, downloading an application, patching a video game), my mouse cursor slows down, and sometimes gets to the point of being completely unresponsive.
No matter how high I place the cursor speed, my cursor refuses to act normally. It travels very slow, sometimes not moving at all, and sometimes moving in short bursts. My left and right click functions might not function and as does my scroll wheel. However, my keyboard works perfectly and is just as responsive as it was before.
Whenever these intense network using instances are closed, the mouse nearly instantly returns to a normal, functioning state.
Incase some hardware & software are needed, I can supply a few:
Hardware
- i7-4770k @ 4.5GHz OC from 3.5Ghz
- 32.0GB (4x8GB) RAM @ 1.6GHz OC from 1.3GHz DDR3
- daskeyboard Model S Wired Mechanical Keyboard w/ MX Brown Switch
- Cyborg R.A.T. 9 Wireless Mouse @ 6400 DPI
Software
- Windows 7 Ultimate Service Pack 1
Some Applications that induce this behaviour
- Google Chrome, Firefox, and Internet Explorer streaming internet video from YouTube
- Steam when patching various games
This sounds like a classic example of a failed overclock. Did you make sure your CPU doesn't throttle under load? Because if it does, your overclock actually makes it slower. (Was it overclocked by someone who knows how to overclock modern CPUs? What's the peak temperature under load?) – David Schwartz – 2014-06-30T02:39:33.063
Network usage causes DPC/ISR usage and this has larger priority than the mouse driver and so you have small lags. – magicandre1981 – 2014-06-30T03:57:29.790
@David - I've OC'd several machines in my life and I am sure I have dont it correctly, and the core temperature has no effect whatsoever on my cursors speed, it is only based on network traffic. Running P95 the cursor moves perfectly even when the processor is under full load, but when only running a browser process and simply downloading a large file, the cursor slows down. – opop9266 – 2014-07-01T00:20:30.967
Then it sounds like a network driver or network hardware problem. What kind of network interface do you have? – David Schwartz – 2014-07-01T02:51:03.567
Please run ProcessExplorer at the same time and look if DPC/Interrupts are high – magicandre1981 – 2014-07-01T04:19:59.733
