Fix GPU memory leak is a client-side mod by someaddon for Fabric and NeoForge, with older Forge files that have since stopped. It patches bugs that leak resources inside GPU memory.
Loaders and versions
- Fabric: Minecraft 1.18.2 to 26.3. The newest build requires Cupboard; some builds for 1.18.2 to 1.21.11 need no dependencies.
- NeoForge: Minecraft 1.20 to 26.3. The newest build requires Cupboard; some builds for 1.20 to 1.21.11 need no dependencies.
- Forge: Minecraft 1.18.2 to 1.20.1, builds stopped after November 2023. The newest build needs no dependencies.
What it fixes
The leaks it targets surface as OpenGL errors. The creator names three of them, and they are the ones to search for in your logs or crash reports:
- GL_OUT_OF_MEMORY
- GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT
- GL_INVALID_FRAMEBUFFER_OPERATION
The page lists no known incompatibilities and says the mod should work with any other mod. That is the creator's claim, not something we have tested.
Installation
Pick the file that matches your loader and Minecraft release, then drop it into the mods folder. If you are new to this, the guides on installing mods on Java Edition and setting up Fabric cover the basics, and Forge and NeoForge have their own guide.
- 1.Install Fabric or NeoForge for the Minecraft release you play.
- 2.Download the matching file from the CurseForge page.
- 3.If that file lists Cupboard as a requirement, download it too.
- 4.Put every .jar in .minecraft/mods and launch with the loader's profile.
Trade-offs
The scope is narrow. It addresses leaks the author identified, so it will not cure every cause of high memory use or low frame rates. Forge users are on the oldest files, because Forge builds stopped in November 2023, and newer releases are covered only by Fabric and NeoForge. The project has been downloaded more than 109 million times on CurseForge, and its last update was in September 2026.
Questions about Fix GPU Memory Leak.
4 questions
What does Fix GPU memory leak actually do?
It fixes bugs that leak resources within GPU memory. The creator lists the symptoms as GL_OUT_OF_MEMORY, GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT and GL_INVALID_FRAMEBUFFER_OPERATION errors. The mod is only required on the client side, and its files are tagged client. Install it in your own mods folder.
Do I need to install it on a multiplayer server?
No. The creator states the mod is only required on the client side, and its files are tagged client. Put it in your own mods folder with the matching loader, and add Cupboard if the file you pick lists it as a requirement.
Is Fix GPU memory leak compatible with other mods?
The creator lists no known incompatibilities and says it should work with any other mod. That is the author's statement rather than a tested guarantee, so if a crash appears, check the issue tracker on the GitHub repository.
Does it work on Forge?
Only older Forge files exist, covering Minecraft 1.18.2 to 1.20.1, and those builds stopped after November 2023. For newer releases, use the Fabric or NeoForge files.
