BF4 CPU/System Lag spikes - NOT FPS

[Bam]

Upgraded to an i5 and new mobo. BF4 now actually looks great, but I'm getting very regimented spikes, as if the FPS were dropping from 60 (I have that as my max atm) to 30, happens every 10s, and lasts for 1-2s. I have the FPS counter up, and thats solid at 60.

I've tried current and non beta drivers, as well as some older 13.xx ones. Any thoughts as to what's causing this, as it appears to unrelated to my GFX card.

Thanks

Out of interest, is the game on an SSD or an HDD? I had a few jitters before I moved it onto my SSD and haven't had a recurrence since!

SSD, along with the entire Origin Games folder.

The spikes are routine, its like something is dipping out etc. Its bad enough to stop me playing, which seems a tad crap, considering I upgraded just to play BF4 on something better than a Phenom

Same on Test Range, yeah. Memory is 8Gb, and nothing running in the background.

I forgot to say that was in DirectX, as any version of mantle seemed to crash bf4.exe, to often to be bothered. That said, using 14.4 now, and seems slightly more stable on my 7870 (Mantle), but instead of graphical spikes, I now have one of those those weird ripple lines, when I move. Hey ho, back to troubleshooting rather than playing lol /facepalm

This sounds crazy but I had exactly this on BF3 till I set origin to not be enabled during game play. That fixed it for me.

This is BF/EA/Origin, sounding crazy is par for the course eh
I'll check, but I normally turn that off.

So, running on Mantle 14.4 (Official not the RC they released just before) seems to be very stable and smooth as butter at 59.94 FPS and VSync on. I've never used Vsync in all my years out of habit from playing Quake/CS etc, its always introduced horrendous input lag, but on BF4, it actually makes input lag better.

Oh well, seems to be running okay for the moment so I'll test again today

Personally I wouldn't use vsync in BF4 either, the input lag is noticeable, I also wouldn't limit the fps to 60, is there a particular reason to limit it?

The input lag with Vsync is not present when I use it. As I mentioned, I'm a long-time advocate of staying well away from it, its the first setting I change "Always Off", but for me, with BF4, and setting FPS to 59.94, it makes my input better, I'm surprised, but I am on mantle, so maybe it handles it differently.

Don't know about op but I find a constant fps noticeably smoother than letting it run at maximum all the time when you have dips from 100+ Down to ~60. So I cap it at 65 to stop that.

Most sites will tell you that 30fps is the limit the human eye can see, but any gamer will tell you they can tell you the difference between 30fps and 50fps on a monitor. 60fps seems to be the happy medium for me, with ultra settings and vsync, no lag, in fact its better, and with the better quality and less fps, it feels smoother than as you say, 125 fps dipping to 80 when the stuff hits the fan.

As an aside, after a map change yesterday, I was getting severe FPS degredation, around 5 fps, couldn't figure it out. Closed Chrome, FPS went back to 60.

BF4 is a sick puppy
