Since day 1 of the new raid, I've been experiencing crashes of my graphics card while specifically in the first phase of the boss fight, when Rhulk sends out the four big blasts in a diamond shape. I have had about 6 of these crashes, and when it happens, the blast starts to go off, and then everything on my computer goes dark for about three seconds. I can then see the lights on my graphics card come back on but I'm unable to get the picture back on my monitors and the keyboard/mouse don't seem to work, so I'm forced to restart the machine manually. It never bluescreens or goes to BIOS, it just goes dark, kind of like a 'brown-out'. On reboot, I don't get any crash message or error, and the game restarts fine. No issues relaunching the game, nothing comes up after multiple scan and repairs in steam. I've tried moving the game to a different drive, playing with literally no other programs open on the computer, not even discord or DIM, nothing seems to make a difference. +It also doesn't seem to matter how long I'm in the activity or how long the instance has been loaded, as I've experienced this crash after being there for hours (contest mode) but also from the first try on a checkpoint which the whole team loaded from orbit. This does not happen in any other game, nor does it happen in any other part of D2, and I have pretty good hardware so I'm inclined to believe it's something in the Rhulk room causing it. It doesn't happen every time, I've cleared the raid a good amount of times already but I'd say I get this crash 1 in every 4 or 5 runs. My specs are: EVGA GeForce GTX 1080ti Intel i7 6700k Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3000 Running D2 through steam installed on my C: drive (Samsung 860 Evo SSD) Sadly I'm unable to get footage of the crash cause I cannot predict when it will happen, and, well you know, the whole computer crashing of it all. Like I said, very much doubt it's a hardware issue, and I'd like to make the team aware of this as this can't be good for my machine or others who are also having this problem, but I really want to continue doing the raid.
