QDAA

Supersampling is the most accurate and most expensive form of antialiasing. Rather than blurring edges after the fact, QDAA renders the entire scene at a higher resolution and downsizes it before presentation. A player on a 1280×720 window, for example, sees the game drawn at 2560×1440 and then resized to 1280×720. Because the work happens before the frame is drawn to the screen, pixelated textures and polygon edges are smoothed, including the edges of 3D item models.

The mod reuses functionality Minecraft already has for macOS Retina displays. It optimizes the final render step by replacing the normal quad render with a blit. Because it covers the whole frame, it also antialiases GUIs, which can make rotated text easier to read. Shaders only work in the world, so their effect is limited to what the game renders there. Mods that change how the framebuffer is put onto the screen can clash with QDAA.
