Performance
Sleepless Nights is made with optimization in mind. We know not every PC will be able to run our mod-pack considering the level of shaders we have installed. If you are having frame issues please try the following;
Reducing render distance by a few chunks
Lower simulation distance
Increase the RAM maximum for the mod-pack
Under no circumstances should you turn the shaders off.

Most common causes: insufficient RAM or wrong forge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 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.

Minimum 6 GB, recommended 8 GB for stable performance. per 5 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 €12/month).
Can I add custom mods to Sleepless Nights without conflicts?
Yes, but check compatibility: only use mods for the same loader (forge) 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.
Sleepless Nights server lagging – performance tips
1) Increase RAM to 8 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.
