I've been dealing with a frustrating problem that I'm hoping there's a documented fix for. Without getting too wordy, the short version of my problem is this: I fire up D2 and play my heart out. I put D2 down for a couple of hours, I do other stuff on my computer, and when I fire D2 back up, there's a very noticeable graphic that's noticeable as the numeric loading graphic starts, it continues at character selection, and never goes away once you get into the game. If I reboot my PC and go back in, it's perfect.
As far as troubleshooting and relevant information goes, I have closed every non-critical process that could be safely shutdown, my drivers are up-to-date as of last night, my game client is updated, and I'm running a liquid-cooled 3080 and x12900 - neither of which are overclocked, 64GB of speedy DDR4, and my only drives are PCIe 4.0 NVMe M.2 SSDs. I can survive by rebooting my machine to play, but it's such a pain in the rear to do it given how much I use my desktop, I'm hoping I'm not the only person that has noticed and documented this problem.
Edit: I can launch any other game and play it just fine, there's no graphical lag or performance issue in anything other than Division 2.
