So I haven't played bf4 or been on my pc for the last 2 weeks and prior to the 2 weeks the game was working fine but ever since I got back onto playing bf4 I've been getting massive lag spikes every few minutes and the last from 30secs to 1.5mins I've checked my graphics card drivers and there up to date and I even use Nvidia's optimisation setting so I'm always at 60fps so if anybody could throw a few suggestions my way on whats up I'd really appreciate it
