Fix GPU Memory Leak Mod FAQ

Watch your log for the GL_OUT_OF_MEMORY, GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT, and GL_INVALID_FRAMEBUFFER_OPERATION errors you were seeing before. If those stop appearing and VRAM usage no longer climbs steadily during long play sessions, the fix is doing its job.

No, it works passively once loaded. There are no in-game settings to toggle, so just make sure it's present in your mods folder and launch the game normally.

The mod fixes leaks, but it can't create VRAM you don't have. If your texture packs, shaders, or render distance already exceed your GPU's memory, you'll still crash, so lower those settings alongside using the mod.

It can fix leaks that cause those errors, but shaders themselves often trigger GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT for unrelated reasons. Try the mod first, then update or swap your shader pack if the error persists.

Not directly. It stops memory from leaking over time, which can prevent the stuttering and crashes that come with a full VRAM buffer, but it won't raise your baseline framerate.

It's designed to work alongside rendering and performance mods since it patches resource leaks rather than replacing the renderer. If you hit conflicts, check whether the other mod already includes similar fixes before reporting a bug.

The errors it fixes are client-side GPU issues, so it belongs in your client mods folder. Installing it on a server won't do anything for players' graphics problems.

Leaks accumulate over time, so the benefit shows up most in long sessions, especially with large modpacks. Short play sessions may not reveal much difference.

No. RAM and VRAM are separate; this mod addresses GPU memory leaks, not Java heap size. If you're running out of regular RAM, adjust your launcher's memory allocation separately.

Remove it and check whether the errors return, then test with only this mod plus your core performance mods to isolate the conflict. Report the issue with your log so the cause can be identified.

No, the mod works out of the box with no config screen or setup required. Just launch the game and it patches the leaking GPU resource calls automatically.

You won't see a new menu or HUD indicator; the mod works silently in the background. The clearest sign is that GL_OUT_OF_MEMORY crashes and framebuffer errors stop appearing in your logs during long play sessions.

No, it only fixes memory leaks that cause crashes and errors, not general performance. If your FPS is low without crashes, the problem is elsewhere.

Yes, it addresses the resource leaks that lead to incomplete framebuffer attachments. If the error persists after installing, another mod or shader is likely the cause.

Yes, it's designed for exactly that scenario and is commonly included in big packs. It doesn't replace other mods' code, so conflicts are rare.

Yes, this mod fixes GPU memory leaks, not system RAM usage. Allocating more RAM is a separate fix for a separate problem.

It generally coexists with rendering mods since it patches leaky calls rather than replacing the renderer. If you still get framebuffer errors with shaders, test without the shaderpack to isolate the cause.

Check that the mod is actually loaded in your mod list, then read the crash log to confirm it's still the same GPU error. If it is, another mod is likely leaking resources and needs to be identified by testing.

It's a client-side rendering fix, so it belongs in your client mods folder. Servers don't render graphics, so installing it there does nothing.

Yes, it doesn't add blocks, items, or world data, so removing it is safe. Your world will load fine, though the original leaks may return.
