About this Modpack
Rabbit's Immersive Optimizations is a project I created with the intended purpose of giving everyone the insanely elevated Minecraft performance I have played with for several months now. Almost all of these mods I selected carefully, and with consideration into how unatural it could make the game feel; as a vanilla+ player, these mods will not be overwhelming or make the game feel heavily modded. However, this modpack is included with vanilla enhancing resourcepacks, shaders, new UI, and block remodels to create an immersive experience without being overbearing.
The entire modpack can be used on a mutiplayer server as it only affects the user's client. Anyone can play this modpack on any online instance to gain a better performance.

Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).
Can I add custom mods to Rabbit's Immersive Optimizations without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
