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.
