DirtyAliasing

FXAA, the Fast Approximate Anti-Aliasing method, is a lightweight pass that softens jagged edges at a small performance cost. TAA, Temporal Anti-Aliasing, is a higher-quality option that blends data from previous frames to stabilize the picture, and it uses neighborhood clamping to reduce ghosting. Both smoothing modes are available in the mod's settings.

A third option, Dirty Upscale, is marked experimental and applies the AMD FidelityFX CAS algorithm as a sharpening filter. It changes the internal render resolution, so the image is scaled rather than only sharpened, and the author advises using it with caution. The mod is client-side only, so a server does not need it, and Cloth Config API is required next to it on Forge.
