Lag issues on Battlefield 4 Beta

Same issue here.

And I have nearly the same system.

Sapphire Radeon HD 7850

Same CPU.

Same RAM.

It's the game,  I play on ultra settings and its smooth as silk and then all of a sudden it goes to choppy goodness. Put it on low settings doesnt seem to change anything. It is just a beta and right now it just doesnt play well. Its not your computer. 

Yes, same here, first seconds on High seem to work well, but then it's lagging like hell.

And I have more FPS on High than Low.

Don't fear, I have this problem too. I won't even try playing until it is fixed. It is troubling that the beta is so poorly done when the game is being released at the end of the month. They have a lot of work to do. My system usually is solid on ultra settings (see below) and changing the graphics settings does not improve the lag

System:

I5 3570k

240 GB SSD for games

32 GB ram 1600

2x 7970 GHz OC

.

Make sure you have the latest beta drivers of your graphics card and set the game's priority to low in the task manager (ctrl+shift+esc) after launching it (for instance during the loading screen).

Did all and still not working, only when i disable 5 cores in bios then it works, on ONE CPU O.o but still beta, i hope realise will be fixed

I just bought the game yesterday and it was my greatest regret. Im pissed that i spent so much money on a game i cant even play because of the lagg!

I literally cant play campain or multiplayer because of this lagg, Im going to die if the next EA update for this game doesnt fix it.😕mileymad:
