So lately whenever I play dota, I'll receive these "lag spikes" every now and then. I'd say it happens about once every couple of minutes, no specifics as to what might be causing it. It's just very sporadic. But it isn't a latency issue, because I'll watch my ping when it happens. And it stays constant. Also the laptop isn't overheating, because it will happen 30 seconds into my first game. Also I've adjusted all of the possible advanced graphics settings down to as low as possible, but it still happens.
