I have the same problem, but it got a bit worse. My entire computer freezes up, making me do a hard reset. Happens after 5-30 minutes of game time. I always play on the same server which has 50 players online always. I've tried vanilla, I've tried verifying cache, I've tried Oc and non-oc components.
I've stressed my cpu and gpu, as well I am monitoring everything on my second screen via afterburner. It seems that as soon as my game freezes everything that is being monitored stops being used, goes to 0% and usually 5 seconds after the computer freezes as well and I have to hard reset.
I wanted to open a new thread for this but for some reason I can't on the forum so I'll port all of my previous RPT files here in a bunch. Sometimes they sync up with the freezing up but most of them aren't correct on their time stamp and I cant remember which one is accurate to the freezing up hard reset problem...

A photo with my phone of afterburner's graphs, I know it doesn't say a lot of but hopefully it'll be useful ._. This was taken after everything froze completely.
