Solution: FPS Drops and Crashes Due VRAM Allocation in Diablo IV
The out of video memory (VRAM) error or screen freezing when opening the inventory or changing zones in Diablo IV occurs due to a resource allocation leak in the game engine graphics. The title consumes all the physical memory of the graphics card and, when trying to overflow the remaining data into the system RAM, it collapses if response times are not optimized.

Step-by-Step Solution
Step 1: Forzar el tamaño de las texturas a un nivel seguro
If your graphics card has 8GB of VRAM or less, setting textures to "Ultra" will saturate the data bus in less than 20 minutes of play.

1
Step 1
Enter the graphics settings within Diablo IV. -
2
Step 2
Lower texture quality to Medium or High. The visual difference in motion is imperceptible, but it reduces memory consumption by a stable 2.5 GB. -

Step 3
Turn off Screen Space Reflections (SSR), which doubles the shading load unnecessarily.
Step 2: Activar la generación de fotogramas con OptiScaler / FSR 3
If you use upscaling, make sure to activate Balanced mode to reduce the base rendering resolution, drastically decreasing the number of megabytes that the GPU must retain in its internal memory for each frame.
Prevention Advice
Recommended security practices:
- Avoid modifying system registry tables to try to 'fool' the game by falsely increasing the VRAM size via software (such as the DedicatedSegmentSize key trick in Windows). This does not add real hardware and usually breaks video driver stability, forcing direct blue screens (BSOD) by demanding a power transfer effort that your integrated or dedicated graphics card cannot physically support.
