About this Modpack
Meet OptiCraft!
OptiCraft - (short from Optimized Minecraft, duh) is a Fabric modpack that aims to provide you with better in-game perfomance for our beloved cube game.
This mod is made to be used a base to create your own modpack. I provide only stable perfomance mods with maybe a few Quality of Life onces, like zoom. So if you want to add a Voice Chat, some animation, maybe MCC Island features or other stuff, GO ON, add them!
P.S. yeah, there a also a few mods that allow customization of models and stuff. I'm pretty much just replacing grandpa OptiFine
Need some perfomance statistics? No! You don't! Trust my word and try it out! Gallery is a very poor representation of what it actually feels like
Highly incourage you to modify any and every available setting for your own taste! (mods also have setting)

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 €5.2/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 (1.20.4). 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.
