Recently bought BF4, and I keep getting really bad lags (about a second and a half hang) every ten seconds, even in cinematics. Change of settings doesn't change much, i'm getting good fps even on high so doesn't seem to be graphics card causing the problem. I've got the latest drivers too.

My setup is

athlon II x4 640 (3.0ghz)
6950
8gb ram

Is my CPU the problem? It's alright for minimum requirements from what I've read, is there anything else I can try?
 
Mantle is a API to use instead of DirectX, you will find the option to use it in the menu of the game.

* Thats if your GFX card is supported by it etc etc.
 
Hmm, I don't have the option. Found http://battlelog.battlefield.com/bf4/news/view/bf4-mantle-live/here that I should have it if i have the following

-AMD Catalyst 14.1 Beta drivers.
-AMD Radeon GPU with Graphics Core Next
-64-bit Windows (7, 8 or 8.1)

I don't have the Beta drivers, but I do have the latest regular release ones. Surely it should run fine without the Mantle renderer?

Should I give the Beta drivers a go?

Tried a few other games and they run fine

It doesnt need mantle to run, DX should be fine (and its what I currently use when I play it) last time I had an AMD card Mantle was broken in this game.

If other games are fine and its just BF4 doing it then I would point all fingers at DICE as they are always screwing things up.
 
If I remember rightly the 6950 wont support mantle a its WLIV4 and not GCN.

Forget those old beta drivers and just use the latest 'Omega' drivers and see if they help.
BF4 is mainly graphics card driven. try to shut down as many back ground tasks as possible to help using a program like 7smoker or 8 smoker pro which are now both free

Just keep an eye on the install options as it does try to install other software with smoker which you can just deny. use the game boost option and see if that helps.

Battlefield 4 - CPU Performance
To briefly gauge how CPU specs might affect BF4's performance, we ran our tests with our i5-3570k at its usual overclocked setting of 4.2GHz and at stock settings (max turbo frequency of 3.8GHz). We also disabled one and then two of its four cores. There are certainly more CPU tests that could be done with BF4, but the main focus of this article is graphics performance.

Analysing these results is very easy. There's virtually zero difference between any of the settings. There's a very slight drop at medium when not using the overclocked settings, but it's almost meaningless. The game did become more unstable with just two cores enabled, however, and locked up a fair few times.

It's possible that reducing the settings further would show up framerate differences a bit more, but generally it's safe to say that you're GPU will limit you before your CPU does. That's not to say any CPU is up to the job, however. The recommended specs for the game list a quad core CPU, and we wouldn't want to use less than this, especially as the CPU would likely play a bigger role in heavily populated multiplayer maps
