Since 0.57 hit stable I have been experiencing freezes/massive lag with a duration of 30 seconds up to 1 minute. These happen frequently (every few minutes) and even with empty servers.
It goes by itself that the times this got me killed (even during "official" events) are a lot...

I am not using startup parameters and I have a pretty high-end computer (i5 2500k, GTX 780, 8Gb RAM).
The game is installed into a Sata 2 500Gb HDD as at the time DayZ came out it was the one hard disk I had available, but I had never experienced such problems until 0.57.

Here is a video I recorded yesterday, for your reference:

I hope there is a solution for this, as the game has really become unplayable for me right now.

Thanks!
