These are the main problems that I’ve noticed:
1: Hard game freeze when starting a game or joining a game. Solo or multiplayer. Must kill Diablo3 through task manager. Seems to happen more often when entering a game starting in Act 2 Hidden Camp. I’ve seen this issue happen several times in a row. The issue comes and goes I’ve seen this issue for several years.
2: Hard game freeze upon entering a rift or a greater rift. Solo or multiplayer. Must kill Diablo3 through task manager. I haven’t seen this often enough to recognize which map set(s) it happens on, or if that even matters. Very erratic on frequency, can happen a few times in one night, or not at all over the course of a month. This is a development within the past couple of years.
3: Random 10-15 second freezes while playing. Solo or multiplayer. Happens mostly in higher greater rifts, but I’ve seen it happen elsewhere. If playing solo, the game automatically goes into a pause state. This is a development in the past couple of years.
4: Stuttering issues playing certain classes or with certain classes. (Wizard) This is a more recent problem.
5: Error when jumping into a friends game. I don’t recall the error number right now, but you have to wait for the error to pop up, then you can join afterwards.
1 and 2 I’ve experienced with my current system and an older system. I don’t think 3, 4 and 5 were present or I didn’t notice them until after I upgraded to my current rig in 2019.
