About this Modpack

OPTIcraft 1.20.1

it is now available on both Fabric and Quilt loaders

Mods

  • ImmediatlyFast : is a performance optimization mod designed to significantly reduce stuttering and improve overall framerates (FPS) in Minecraft.

    It achieves this by replacing the game's default renderer with a highly optimized version, leading to faster loading times and much smoother gameplay, especially in large modpacks RaphiMC♥

  • IrisSHADERS ( for shaders supports ) : is a powerful and open-source mod that acts as a modern replacement for the traditional rendering engine in Minecraft. Its main purpose is to allow players to easily use shader packs with much better performance and compatibility than older shader mods coderbot♥ IMS♥

  • Lithium : is a general-purpose optimization mod that focuses on improving various aspects of game physics, chunk loading, mob AI, and other server-side (or single-player) mechanics without compromising vanilla parity.

    Unlike visual optimization mods (like Sodium or Iris), Lithium improves the logic and processing speed of the game itself.

    Key Benefits:

    Reduced Lag: Significantly reduces server-side lag (tick time) and improves the responsiveness of the game.

    Compatibility: Works seamlessly with most Fabric mods because it only optimizes existing mechanics caffeinemc♥

  • Sodium ( and Sodium extra ) : a revolutionary, free, and open-source rendering engine replacement for Minecraft. Its primary goal is to drastically increase framerates (FPS) and reduce micro-stutters, particularly on low-end and mid-range hardware caffeinemc♥

Frequently Asked Questions

OPTIcraft server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a OPTIcraft server really need?

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 OPTIcraft without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.20.1). 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.

OPTIcraft server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
