I have now tried different drivers, Re-install of BF4, DX & Punkbuster.....
Still the same issue that when the game starts it all runs in super slow motion then crashes to desktop.
I tried using the EA online help but all it could offer me was a link to the online manual ?
It was working fine 2 days ago ??
Disabled hardware acceleration in the browser and animated backgrounds in battlelog?
I had to use the nightly build of firefox or the browser plugin for battlelog was doing weird things with the game and crashing a lot for me. (Stable builds of Firefox and Chrome having various issues - not retested with the more recent updates to see if its gone away).
