Here are the best Minecraft Shader—Complementary Unbound 5.4 settings on RTX 4070 Ti Super, alongside the Neoforge Beta branch.

As the name suggests, Complementary Unbound shaders offer the most intensive ambient lighting effects, ambient occlusion, and accurately simulated shadows. They also introduced a major lighting overhaul in the Minecraft game. Gamers targeting the 4K resolution with the 4070 Ti Super can expect a visually stunning experience. Thanks to Ada Lovelace’s improved OpenGL raster performance, gamers can absolutely max out all the shader settings and still play easily. If high refresh rate gaming is a requirement, then a few adjustments are required. The settings below paint a perfect picture for an eye-candy experience.
The recommendations are based on Neoforge beta mod loader alongside Iris and Sodium with Minecraft version 1.21.5
