Massive performance problems in BF4

Ok so heres my specs:
I7 4770k @ 4.4Ghz
8gb Patriot viper 2133Mhz
2x GTX 680 SLI
1440p monitor running at 96Hz
Windows 8.1

Now this is a pretty high end system but I'm having major problems getting BF4 running smoothly. When i load up a game my fps starts at around 90 but quickly falls to between 30 and 40 with regular dips below 30 when the action really kicks off which just isn't acceptable. I'm running most settings on high in game with a few on medium and no AA so its not like I'm trying to run this on ultra!

I'm using the 331.65 drivers and have gone over my settings to make sure that SLI is on and all that (yes the monitor cable is plugged into my top card as well ;))

Any suggestions? Its very frustrating as i know that i should be seeing much better performance. Vram is peaking at just over 1700 so its not hitting the vram limit (although it does go over 2gb on ultra which is another problem entirely)
 
Have you disabled core parking in windows? I have the same set-up but 780s instead and installing a little app called parkcontrol worked wonders for me. If you dont know what it is,windows will only use 4 threads when needed and wake the other 4 up when ready so this program basically leaves all 8 awake
 
Do you run with post processing? There's a 670 sli user that found post processing on high/ultra was causing a similar problem. If so turn it off and see how you get on.
 
This game is buggy as hell. I get massive fps but it is smooth sometimes and jerky as hell the next. I have no idea what the problem is but it is starting to bug me now. Even on 1080P (which I have been playing all night, it just doesn't feel smooth like it should do in all the matches.

To me, it is Dice and hopefully they will have a fix soon. Annoying is hell, as the beta ran sweet as for me.
 
Is sli actually working? The latest drivers didn't work for me on Windows 8.1.
I could see my gpu usage with MSI Afterburner in my Logitech lcd screen and the top card would drop to idle shortly after the round started and only the 2nd card would be working and it was a jerky stuttery mess. I ended up doing a clean install with 331.58 drivers and these worked.

SLI is now working, just need Nvidia to optimise it :) Ooh and EA/Dice to fix the server/client crashes, dodgy net code and sound bugs :D

I would also try unparking your cores, I ran the program and discovered I had 2 cores parked :(
 
Thanks for the suggestions guys! I unparked 2 of my cores last night but that didn't really seem to help at all. Windows parks the cores to save on power I'm assuming? Shouldn't they unpark themselves when you fire up BF4 anyway?

I'll try lowering post processing tonight when I get home, I think its already on medium though but will double check. As for SLI, I did check this late last night and noticed that my top card was hitting about 98% usuage but the bottom card was fluctuating at around the 68% mark. Is this normal or should both cards be under the same load?

I'll leave HT on for now as BF4 makes use of the extra threads so the I7 should be giving a nice performance boost over what i'd be getting with an I5

Why do people recommend this, i played on bf 3 last night (with an i7 2600k) usage was at times 60 odd percent use. If i turned HT off it would max out.

some seen difference with it.
might have to do with the OS etc..
bf3 is different than Bf4.....
coded differently.
