I have the same problem. I had it before the patch, like every few hours it crashed.. mostly connected to skill effects as far as I could figure it out. But after one of the latest patches I get a lot more crashes, like every 30-60 minutes. (Sometimes 5 in a hour and sometimes none in 4.. not really connected to player-mass I think)
And sometimes my video and sound is like freezing and I have some kind of video error where the screen splits into single pieces and changes when I move the mouse. Can’t really explain it any better since my english isn’t too good, but I don’t have such problems with any other game!
Could it be connected to nvidia or intel? I mean, my pc isn’t that up2date but can handle most actual games in low-middle settings and I have no fps problems whatsoever. I can’t really figure it out and it seems not to help changing the settings up.
