BF4 PC stops responding to mouse and keyboard input

anyone find a solution? anyone ....  ?? 

Sadly it seems to be "Fix your game, DICE!!!!!!" If you've got a 7000+ series AMD card, I'd wait for the Mantle patch which should hopefully take some of the strain off the CPU. On the issues tracker, there's also an item that mentions framerate drops that I think may be related to this issue. Wishful thinking atm ho hum.

unfortunately I think it's not a problem of AMD Series. I say this because I am experiencing the same problems as you and I have a NVDIA 560Ti. I just do not know what else to do. It remains only to exchange memories, cpu and video card.
I had the same problems with BF3 and could not resolve.

If anyone has another answer or idea, please share.

Lambdoid, what is ur cpu btw ? 

Please change this domain name to Question HQ!

It's an AMD x6 1090T.

Guys, i have good news ... at least for me ...  but i hope it works for u too....

when I was playing bf4 i left running in background  the resource monitor of windows.. ( u can access it  by windows task manager - performance tab,) and then, when bf4 stopped responding i could see the THREAD and PROCESS that was occasioning the freezing. the proccess called MPK.EXE,  a proccess sourced by a software.  Resuming ....  I hope that using this feature (RESOURCE MONITOR, CPU tab, u guys can found the THREAD that is causing so much problem and SOLVe it.      😕mileylol:

this isn't really a solution

There seems like there is some memory leaks somewhere. I suspect it is the amd drivers. I can find other incidents like this. I am trying to update to the newest beta-drivers right now to see if it improves. Could also be BF4 that has memory leaks. If that is the case, then: "Fix your game EA".

I've tried the beta 14.1 and 14.2 drivers, but they seem to make the problem worse, and that's with both DX and Mantle. I'm waiting until the next stable drivers are out, and until then sticking with 13.12, as there are still random CPU spikes, but they tend to be less severe. If there's a levolution event, the CPU usage goes mental. There may be memory issues too. I haven't tried the 32 bit exe. That might help.

OK, solved for me at least....................................

You accidentally hit the ~ key. Hit it again and viola!
