How it works
Minecraft has to render a lot of textures when drawing the advancements screen. These include
- the background
- the icons
- the lines
For each one it draws all the textures individually, requiring communication with the GPU each time.
The mod improves performance by batching most draw calls, so only a single one is made. Furthermore, it avoids drawing textures which are outside the advancements screen.
