Here to raise this thread from the dead.
This just started happening to me as of this morning, not sure if there was an update or something, I didn’t change my PC at all.
Game usually runs at a solid 100-144 fps, depending. Since this morning after changing zones, sometimes after a certain amount of time, the FPS would drop noticably, giving me an awful stutter. Despite being able to visually see (in the flickering flame of a braizer in town) that I was actually rendering something like 5-10fps, the in-game fps counter was showing me 50-70.
So, it was reporting improper FPS, which is strange. Stranger still, I noticed that Diablo 4 was using a WHOPPING 10 GB of my available RAM. I have 32gb so it’s not like the system was struggling, but I have never seen a game use quite that much ram, especially not one that my 1660XT can run on mostly ultra settings very well, up until today. As of typing this and after restarting the game, it is hovering around 6gb with 120fps in Kyovashad, which is expected.
I am running High texture quality. I have both foreground and background FPS set to 144, on my 144hz monitor with vsync enabled. I have disabled hardware acceleration in battle net launcher, as well as set it to shut down when the game is launched. My drivers are up to date.
I have messed with pretty much every setting that I can, and the problem seems to persist. D4.exe is allowed on private networks.
Restarting the game every 15-30 minutes is a huge pain in the buns and I hope this gets addressed soon. Didn’t realize how prevalent the issue was until I typed it in google.
Edit: After about 30 minutes of gameplay I’m back to the actual 10/reported 60 FPS stuttery nonsense, D4 is eating up 11.3GB of RAM.
