Question / Help Mouse stuttering while webcam is on

[bielzishot]

Hi,

I've recently started streaming some things at twitch.tv. I have poor connection but I managed to figure a way out of this problem, so that's not what I've come here to ask about.
Since the first day, I tried to make my streams with the webcam on. However, everytime I turn it on, my mouse starts to stutter, like, a lot. It keeps jumping to the direction I've pointed, I never actually see it go there, so it makes impossible to play any game that require mouse.
However, my wireless mouse works normally. I doesn't stutter, nor freezes, nor anything.
Does someone know a way to fix this?

My specs:
Intel® Core™ i5-2400 CPU @ 3.10GHz
8gb RAM
ATI Radeon HD 5500 Series
Wireless mouse - Logitech k260
Mouse - Genius XScroll

Can you post your log? viewtopic.php?f=6&t=97

This is most likely a hardware issue. OBS activates multiple devices, video, webcam, audio capturing, then it also activates the encoder. Most likely somehow it's interfering with your mouse. Usually this is a sign that there's a bad piece of hardware in your system somewhere, because stuff like this is extremely rare to see.

Maybe you're right, but I found it weird that this doesn't happen when I tried to stream using XSplit.

Oof, you're using Monitor capture with Aero enabled on Windows 7. That will massively kill your performance. either disable Aero, or better yet, don't use Monitor capture at all and use Window capture instead.

I'm aware of the issues Aero or Monitor capture may cause, I was just hoping that someone would know why my wireless mouse works normally while the "normal" one doesn't.
