2500k usage - is this normal?

[Moothead2]

Is it normal for an i5 2500k @ 4.4Ghz to be sitting at 50%+ usage while watching a Twitch stream (Chrome) and browsing OCUK? I also seem to sit at around 70%+ when running Borderlands 1 which is a 6 year old game at this point. It just seems rather high.

Thanks.

Look in Task Manager to see what is using it.

If it's not clear enough, use Process Explorer (on Microsoft website)

svchost seems to be using around 25% and Chrome about 20% with about 7-8 processes. Everything else is below ~0.1

It's conceivable that chrome could use up a good amount of your CPU time depending on what you have open in your tabs. A single HD YouTube video for instance could take up 5-10% of your CPU.

That means one of your services is hogging a core by itself - a sure sign something's gone wonky.

You'll need to use process explorer or (if you're using Windows 8 or newer) go into Task Manager, right click on the offending svchost entry and choose "go to service(s)".

^What he said. which os is it?
There are loads of svchost instances, Process Explorer will tell you which services are running on that particular instance.

Svchost using 25% has always been an update in my experience. I've always just left it to do it's thing, sometimes overnight if necessary.

Twitch uses loads of CPU as it uses flash which is old, unoptimised, insecure crap.

This. That 25% is going to resizing (to full screen) the flash player. It's some media server in svchost IIRC.

If it's maxing out a core and you turn on the video stats in twitch and watch the dropped frames you'll probably see few/none at the regular size, but some (maybe as many as 10/second for a 30 FPS stream) at full-screen.

I found Opera is higher performance than Firefox at the same task (fewer dropped frames/higher FPS) but not tried Chrome. I'm still using a core 2 quad and increasing the overclock from 3 to 3.25 helped a lot. Nice to see a 2500K at 4.4 has the same problem.

P.S. this isn't to do with GPU hardware acceleration, that is probably still working normally. It's about the resizing of the window.
