cpu usage over 90% i5 4670k
not sure if the game is still not optimised or i have hardware issue. ive read a lot about cpu spike and have tried probably everything i can. i saw that my cpu is always over 90% while playing bf4 a...

since it's not HT enabled it is nomal, because BF4 uses CPU powers alot. In win 8.1 bf4 uses ~80% of i7 4770k@4.2GHz
if i disable HT on my i7 4770k it is 100% loaded as well, and i do have some fps drops due to CPU/memory combined with software. But when it occurs my CPU isnt 100% loaded and my 2SLI 780 GTX Lightnings are not 100% loaded either.
Partially Win8.1 solved the issue (70fps min -> 100fps min) but the bottleneck still exists somewhere in software or OS.
you need to check out if it is your GPU that bottlenecks you or software. In order to do so just check you GPU usage while expiriencing lowest FPSes if its not 100% then upgrading win7 to 8.1 would help. More info and benchmark you will find here http://www.overclock.net/t/1433904/comparison-of-windows-7-vs-windows-8-8-1-ht-enabled-vs-disabled-on-battlefield-4/130#post_21303405
as for solving this, try going MESH DISTANCE = high, MSAAx2, FXAA=medium, Occlusion=SBAO, render quality 90%. This might make it playable with minimum losses to image quality.
im getting over 90% usage for cpu and gpu, sometime its at 100%. i have updated bios but didnt change anything. i cant figure how i can disable/enable HT in bios, i dont see where it is. looks like w8 gives more fps but i wont change that just for a game, this is ridiculous. i cant believe i have those fps drops even with that rig. i guess the game is just not optimised. ill wait for the next patch witch is coming in 2 day and see if it change anything. if not, then ill do a clean up and reinstall w7.
you don't have HT on your processor.
It seems to be both game wich is not optimised for now (it is clear when u see frame time variance disturbance and compare it to optimised game like quake live) and microsoft software which doesn't deliver the result it should, even in their own directx api.
here is quake live frame time varience (notice how smooth it is)

Try to find if there is some software starting at boot time that is causing an issue. Do a clean boot and see what happens: http://support.microsoft.com/kb/929135
that doesn't help.
It seems that more or less everyone has those high CPU usage issue, those who got top tier cpu don't mind too much, cus it doesn't affect them too much, but those with weaker cannot achieve decent fpses even with 700$ GPU and 300$ CPU which is kinda weird.
