When experiencing modded Minecraft, gamers look forward to the Forge mod loader and then use Optifine for optimization or pair Forge with Oculus and Rubidium. However, this guide takes the most efficient approach. Neoforge is paired with Sodium for optimization and then Iris for shader support.

Not only are the optimization benefits from Neoforge targeted, but also Sodium and Iris, which enable the RTX 4080 Super to push high framerates with the Unbound 5.4 shaders at 4K. Follow the settings below to achieve a pleasant gaming experience.

Note- It’s perfectly reasonable for gamers to pair high-resolution texture packs with these shaders to leverage their GPUs’ power. However, NeoForge still has limited support, so you must choose texture packs based on compatibility with CTM (Connected Textures Mod). If your modlist requires Optifine, only the shader settings will make sense from here. The images shown here reflect the Faithful 64 texture pack.

If you are a Patreon subscriber to the Faithful mod project, you can easily pair the 1024x textures at 4K with your 4080 Super GPU. According to our observations, the maximum VRAM usage reaches 14GB after several hours of play, including clearing dungeons such as the Ancient City. Use these settings as a baseline, and adjust the RP Support option if you use a different set of texture packs so that the shaders apply lighting adjustments correctly.

Try these shaders with a custom texture pack, as you have ample GPU power at your disposal. You can even try the Optifine and Rubidium combination, which increases the possibility of resource packs significantly.
