SMAA Iris Shaders adds a special smoothing filter to your game. It uses a technique called SMAA 1x to clean up jagged lines on blocks and items. This pack keeps the normal vanilla look of the world intact while fixing rough visual borders. You get cleaner graphics without changing the original style or losing frames.
Features:
- Edge Smoothing: Removes the rough, staircase-like lines on block borders and distant objects.
- Keeps the exact same lighting, shadows, and colors as the base game.
- Runs fast on older computers because it only focuses on fixing block lines.
- Applies the SMAA 1x filter to make the screen look clearer.
