High VRAM Usage

The client stutters or crashes with an out-of-video-memory error when using high-resolution texture packs. The GPU does not have enough VRAM to hold textures that large. This is a client-side problem.

What does this error mean?
Textures are stored in GPU video memory (VRAM). Very high-resolution packs (512x and up) consume far more VRAM than default 16x assets. When VRAM fills, rendering fails or the game crashes. 
Out of video memory
Most Common Causes
  • A 512x or higher resolution texture pack.
  • A GPU with limited VRAM.
  • Shaders on top of high-res textures multiplying VRAM use.
  • Very high render distance increasing the texture working set.
  • Multiple heavy packs stacked together.
How To Diagnose
  1. Note the pack resolution you are running.
  2. Check your GPU's available VRAM.
  3. Test with a lower-resolution pack to confirm.
  4. Watch VRAM usage with a monitoring tool while playing.
Recommended Fixes
  • Lower the resolution
    Switch to a 128x or 256x pack to fit comfortably within your VRAM.
  • Reduce render distance
    A smaller render distance lowers the texture memory footprint.
  • Drop heavy shaders
    Disable or lighten shaders that compound VRAM usage.
  • Upgrade the GPU
    For permanent high-res use, a GPU with more VRAM is the real fix.

Frequently Asked Questions

No, texture rendering and VRAM are entirely client-side.

128x-256x suits most GPUs. 512x+ needs a card with generous VRAM.

Yes, significantly, especially combined with high-resolution textures.
