Appreciate the effort.. but i use CCleaner regularly. Just to refresh my doings:
Completely cleaned my computer and installed Windows 8.1 Pro. Using Creative drivers for my X-fi Fatal1ty card, and atm AMD 14.4 WHQL for my Radeon 270x card. (As i said before, i tested this fresh installed with nothing but the windowsupdate drivers in the beginning, and had the same troubles)
Problem is a bit worse in Windows 8.1 vs. what it was in Windows 7.
On a positive note, Mantle seems to work a bit better in windows 8.1.. but not there yet for my slacking 270x card. Possibly in the next release tho, but for now it seems a bit better in DirectX. Ive gained some fps i guess, as the gameplay in general seems a bit smoother. Everything set on "Low" on the graphics settings to make sure im not lagging due to gfx stress atleast.
Have run a ton of latencymon, but no clear culprit there.. Meaning its random .dll's that seem to pop up as possible causes, so id say i cant pinpoint anything exact there.
Running 2 1080p MKV's + playing mp3 music and youtube videos is even smoother than in Windows 7, and have absolutely no sound problems at all.. even latencymon is not complaining at all when i do that. Fire up BF4 and WHAM.. all hell breaks loose ☹️
Did some farcry gaming and whatnot without problems.. Thinking about installing Diablo 3 just to see if there is anything there, but was not before.. neither was it any problems in WoW.. The ONLY SINGLE game i have EVER had sound issues in (in this millennium atleast) is Battlefield 4.
Normal sane conclusion of this would be: The game Battlefield 4 has some bugs in it that i experience.
Dice insane conclusion: Your hardware is broken.
I dont know.. Not sure how many ppl come to this forum when they experience problems.. but as i posted before, the issues im having is more or less like the mass problems ppl had with the game after the january patch this year. This WAS fixed in a later patch, but im still having the issues. And from the lack of posts here, it seems im the only one in the world to have ANY problems with this game 🙂
Some day i will figure it out, and it will most likely be something totally daft like swapping places on the usb keyboard and mouse :P
