CPU spikes in Windows 8.1 resulting in erradic micro freezing and FPS suttering in games. Problem never occurred in W7.

Hello. I recently upgraded my OS from Windows 7 Home Premium to Windows 8 pro and then furthermore to windows 8.1.

Before in Windows 7, I ran most of my games fine without any hitches. I'll post my system specs here.

CPU: Intel core i5 2400. 3.1 GHz.
GPU: Gigabyte GTX 660ti OC edition.
Ram: 8GB DDR3.
Mobo: Asrock Z68 Pro3 Gen3.

While at first indeed, I did notice improved performance in games such as Battlefield 4 over Windows 7, at certain times my game would almost freeze for up to 1-2 seconds at a time, dropping my in game FPS from a constant 60 to 1.

I originally thought this was due to some kind of Memory leak, but upon checking my CPU performance in the task manager during these moments the game freezes/micro shutters, my CPU usage drops all the way down to almost 0%, and only during these periods before it rockets back up to it's normal usage during running the game normally. I also thought this was only persisting in Battlefield 4 but upon playing more titles such as Bioshock Infinite and Borderlands 2 for example, I can confirm the problem still persists there, however much less common.

Has anyone also experienced problems such as this in W8.1? I'll admit, I haven't activated my copy of Windows 8.1 yet, due to me wanting to try it out before I buy to see if the optimization hype is true. But if this experience continues after I activate the OS, I will be very unhappy indeed.

Is it strange for these micro/freezes and CPU spikes occur in Battlefield 4 the most?

Also worth noting is that it seems to not occur at all (or not as much) when I disable V-sync in my games completely. However I haven't really played any games long enough in this manner to confirm is this is true, or if it will again persist with these settings, due to the horrible screen tearing that persists without V-sync.

What I also find interesting is that these spikes are dipping down to almost 0%. Not spikes that peak 100%, which seem to be much more common.

If anyone has any possible suggestions or fixes I would be very appreciative. Thank you. :)

  1. Only suggestion I have at the moment is to check for a BIOS update.
  2. After doing a clean install of my Nvidia drivers and rebooting my computer, after playing BF4 for 30 minutes I am yet to run into another hiccup.

    Fingers crossed It is fixed. I Don't understand how this affects the CPU but hey, I'm not complaining if it ends up working.

    (Problem still persists, I will try the BIOS update now and post results)

    Edit: Updating my BIOS had no effect.
  3. Bump. I really need a fix here, this is urgent.

    I just installed a legit copy of W8.1 I purchased and the same problems still persist. This is very frustrating

    Here is a pic of what is happening.


    I have tried updating my BIOS.

    I have tried a legit re-install of W8.1.

    I have tried every Nvidia driver under the moon.

    I have tried re-installing my games.

    I have tried defragging my Hard Drive.

    I don't know what to do.
  4. I have a similar problem but my screen its not freezing my FPS hase dropt a lot in some games and if i have V-Sync on drops a lot more and i have windows 8.1 Enterprise for 90 days to test it .Wen i had windows 7 i did not have this problem i think Windows 8.1 its not good for gaming .
