This has been a frustrating week or so... Before you ask if I've done x, y, and z, please understand I've tried everything possible. The issue isn't with my system, software, hardware, and so on. I've done everything I can to rule that out, including fresh wipes and installs of Windows 10, all updates, underclocking my GPU, reverting back to previous GPU drivers, scan and repair of the new install of D2, and anything else one could imagine. The issue is apparently with the game, and it only started since the last patch. I've been playing since the beginning (600+ hours) and have never had an issue like this until now. Again, this only started after the last patch, as far as I can tell. [b]EDIT: Tried using VSYNC and limiting myself to 55 FPS (odd number, but that's one of my options - I play on a 165Hz monitor, so this isn't exactly lightning fast gameplay), and I was able to play for several hours crash-free. When I tried doing VSYNC at 165 FPS, I would get the crashes. I can only guess it's some bug in the latest patch that causes too high of FPS to crash the game and restart your system. FWIW.[/b]
