I haven't had any chugging/stuttering issues like this. Can you try disabling Origin in-game overlay and see if that helps?
I still get crashes unfortunately. Either the game freezes with audio stuttering, or bf4.exe crashes with msvc10.dll error.
You should be able to get rid of the msvc10.dll crash by reinstalling the Microsoft Visual C++ 2010 Redistributable Packages (both X86 and 64bit).
Yeah. What's annoying is my ping will be like 20-50 depending on the server I join, and it just runs like crap.
I fired up BF3 again a few minutes ago and it had zero problems. Ditto Cod4 lol, though that's older than my balls
Combo of my internet + BF4 makes it basically unplayable.
How about setting network smoothing slider to 0?
