What is Optidium?🔎

Optidium is a modpack that gives you high performance even on potato PCs. This is achieved by using performance mods such as the infamous sodium mod and immediatlyFast. This modpack favours performance rather than QoL. It features strong support for older versions of Minecraft like 1.19.4 and 1.18.2 with the most updated mods!

Why is it called Optidium? 🎇

Optidium is called Optidium because it uses Sodium and but uses features from OptiFine, such as the zoom feature and connected textures. Sodium often boosts performance better than OptiFine on most PCs as they use a much newer way to render objects which greatly improves frame rates and stuttering while fixing many graphical issues.

Does Optidium support shaders? 💡

Optidium does support shaders as it uses Iris. Iris uses a method known as Shadow Frustum Culling to reduce the cost of one of a shader's major performance limiters which is of course shadows, and this allows iris to run better than OptiFine's built in shaders on most PCs
