It is now possible to set Max HUD Framerate (GUI) to unlimited.

Three options have been ported from prior versions of Gnetum:

  • Downscale HUD Framebuffer: uses a smaller resolution for the HUD framebuffer, which may improve performance in GPU-bound scenarios
  • Max HUD Framerate (GUI): allows using a lower HUD framerate limit when a GUI screen is open, improving performance in GUIs
  • Hand Caching: allows caching the hand (currently disabled by default)

Additionally, these changes have been made:

  • Debug Overlay caching has been added (currently disabled by default)
  • Fixed HUDs not rendering with Very Many Players mod

This version adds two new options that may improve performance in certain scenarios.

  • Downscale HUD Framebuffer: uses a smaller resolution for the HUD framebuffer, which may improve performance in GPU-bound scenarios
  • Max HUD Framerate (GUI): allows using a lower HUD framerate limit when a GUI screen is open, improving performance in GUIs

This is a major update to Gnetum, rewritten for multi-version and loader support.

Highlights

  • Migrated to stonecutter for easier maintenance of support for multiple versions and loaders
  • Updated to Minecraft 1.21.11
  • Fabric is now supported

HUD Ordering & Distribution

Previously, Gnetum had an extensive configuration system that allowed arbitrary change of rendering orders. This, while being flexible, was error-prone in that rendering order was not guaranteed, resulting in potential rendering artifacts.

Starting from this version, the original rendering order of elements is strictly unchanged; it is still possible to disable caching of individual elements. Additionally, Gnetum can now automatically distribute elements evenly over passes based on their rendering times, improving FPS stability.

Config

This versions makes use of Sodium's Config API, meaning you can now configure Gnetum from the Video Settings screen, as long as you have Sodium installed.
