Stuttering on PC, seems to be VRAM related?

I’ve played around 2 hours of the Diablo 4 beta this evening and while performance is fine the majority of the time, there’s been a lot of stuttering that I suspect is a VRAM limit being hit?

For the majority of gameplay, the game is running fine and hits the 120 FPS cap that I’ve set in-game which matches the refresh rate of my monitor. However, there are moments where my FPS drops well below 60 FPS and my game stutters for 1-2 seconds. It’s most noticeable when traversing the overworld but it’s happened in dungeons a few times during heavy combat sequences.

I’ve left HWiNFO running in the background while playing and VRAM usage seems to constantly sit between 11-12 GB of usage. System RAM usage for the entire system also sits at around 28-32 GB depending on what’s going on in game.

In-game settings:

  • Windowed (Fullscreen) - which is 3840x2160 120Hz
  • HDR On
  • V-Sync Off
  • DLSS Quality
  • Max Foreground FPS: 120 FPS
  • Quality: High
  • High-Resolution Assets are installed

PC Specs:

  • AMD Ryzen 7 5800X3D
  • 64GB DDR4 3600MHz
  • NVIDIA GeForce RTX 3080 12GB (Game Ready Driver 531.29)
  • Corsair MP600 PRO LPX 4TB
  • Windows 11 Pro 22H2 (OS Build 22621.1413)

Agree with this VRAM problem. I’m playing with similar hardware and 4K high texture quality. It will use all the VRAM when playing. A solution is to switch texture quality from high to medium. It will help a bit, but the VRAM usage will still grow to max. Many other posts also think there is VRAM memory leak this beta. Please fix this in the released version.
