Why are you using windows xp?

Just set affinity to only two cores in task manager

>Asks /g/ for help while posting screen shot of xp task manager in 2017

Kill yourself.

I should have mentioned that the pic is from google. I just googled 100% CPU and grabbed a pic instead of screen capping.
I'm using 10.

Probably malware or antivirus(use common sense 2017)

Firefox runs just fine on my core 2 duo

No but seriously, the creators' update or whatever has fucked some shit up in Firecux for me too.

Install Gentoo.

That's because Microsoft don't want anyone else's but their own cock in your asshole and will fuck with browsers that aren't edge to coax you into using it.

I'm running the 5820k OC'd to 4.2Ghz with Win 8 and I too occasionally get a choppy cursor movement and stutters with this piece of shit browser.
It also often crashes after couple of days of being open.
Watching flash videos on it is pure hell.
Never any problems when using Chrome, no matter how many tabs I have open.
FF is simply a terrible browser.

There's your problem.

C-F5 brings my (overall) cpu usage to 14% for a split second and opening the big generals on the board is about the same.
I saw ~60% util on core 0 at the same time but that is it.
using Firefox 52.0.2 with 4chanX and OneeChan so this shit isn't light either

if your Desktop becomes non-responsive/jerky underload maybe it is time to switch to a OS with a real CPU/IO scheduler.

Recommendations?

I honestly don't know why I bothered asking.

That was another anon, not me.
but memes aside the Linux kernel does have a decent CPU/IO scheduler (several in fact)

I can easily max out each core and still have silky smooth video playback and a responsive desktop.
You could try setting the priority of certain processes higher or lower in windows to fix it however.

That's probably your problem.

>>60112686
You could stop using Windows XP any fucking day now.
