CPU bottleneck because of Windows 10?

[Senzelian]

Hey techies,

 

I have Win10 now for 4 days.

Mostly it works fine, apart from all the downloads and uploads it is constantly doing for whatever reason and this problem I just discovered while playing Battlefield 3.

I never had any problems with my CPU so far, but suddenly it runs at nearly full load while playing Battlefield 3.

I also noticed stuttering in BF3 and just low fps overall. My GPUs are almost falling asleep while gaming.
I haven't tried this with any other game yet.

Is there something I can do to reduce active tasks and are there in general things I should do to optimize Windows 10?
Any Tips?

Edit: After I closed the game I just saw that it is idleing at around 70%... Yup... Makes so much sense
Also, what the f* is runtime broker? ôo

What cpu? Have you unparked cores? My i5 has no issues in bf4 on windows 10. If anything i've seen minor improvements out of W10.

That Runtime Broker is causing hell over here too. Hope someone knows what it actually is

i5-4670, see my signature.

What are unparked cores?

Meh it doesn't really affect gaming performance so don't worry about it unless you're finding that there are slowdowns when doing minor tasks. Do a virus and malware scan. Also, this site is bery helpful and they have a decent guide for disbaling uneeded features on windows 8.1 that are aslo on windows 10. http://www.askvg.com/master-tutorial-to-make-your-windows-8-super-fast/

Thanks for the site, but I already got a solution...  :rolleyes: 

I simply killed the "Runtime Broker" task. Suddenly my CPU is on a max of 10% load again.

So it is really just that one task, which is actually from Microsoft that turns my CPU into crap.

I just wonder how I can avoid that in the future.

Close any modern UI apps.

Well, that's why said scan for malware/viruses. I don't have that on my Windows 10.

It's in C:\Windows\System32 and in Properties it's digitally signed by Microsoft

I KNOW A FIX FOR RUNTIME BROKER. So this was pissing me off as well. I have a frikin 4.4 GHz i7, and I was idling at like 35% CPU. WHAT THE ACTUAL F*&@.

 

Did a lot of googling to try and figure it out and did come across a setting that helped. I am at work so I can't easily look for the thread, and not on windows 10 here so can't just figure out where it was. But there is a setting that is "show me tips about windows". turned that off, and everything went back to normal!

Found it!

It isn't malware or a virus.

Whatever it is, it comes directly from Microsoft and was already on Windows XP, Vista, 7 and 8

It only seems to appear for some users.

Runtime Broker kept thrashing my system, usually using 40% of my CPU although memory use wasn't much, according to the Task Manager. I'm currently using Windows 10 Pro x64 version 10240.

Runtime Broker is a service called Time Broker, which can be disabled through editing the registry.

Right-click on the Start Menu Icon. Go to RUN and type regedit.exe and select OK.

Find the following entry:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBroker] "Start"=dword:00000003

Change the 3 to a 4.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBroker] "Start"=dword:00000004

4 is Disabled, 3 is Manual and 2 is Automatic startup.

Before editing, the original value was 3. Set to 4 to disable. Just change the 3 to a 4 through the MODIFY menu selection, exit regedit and reboot your system.

After this edit, Runtime Broker no longer runs and the CPU at idle is now only 0 to 1 or 2 percent.

No adverse affects after disabling Runtime Broker on my system.

Thanks, I also found a fix by editing the registry and disabling runtime broker.

Yeah, i still had it enabled and din't have the problem. Weird.

It only seems to have problems with certain apps.

Here is what another use wrote in a Microsoft forum:

Hello again,

You are right. This has become a great problem now. I have done further research and have found that runtime broker and its memory related issues are due to apps with faulty codes that result in memory leaks. The source of memory leaks are very difficult to find. However since my windows installation is relatively new, I have tried uninstalling my apps one by one, and have zeroed in on my antivirus software (Bitdefender total security 2013). I uninstalled it and the runtime broker's memory usage improved immensely (it held at a max memory of 60 mb).

I reinstalled it and almost immediately RUNTIME BROKER's memory usage kept rising. Therefore I guess it is safe to assume that it is my antivirus software which is causing the problem. However since I have already purchased this product, I have no option but to report this problem.
