Not Just Fast
Not only optimization mods, but also quality of life!
About this Modpack
In short
- A lot of optimization mods
- Some cool visual mods
- Some QOL mods
- Includes Thymine (a cool mod which fixes double-flickering bug when sneaking, also has fullbright feature and some toggles for pvp)
- Does not include a mod for FPS lock and limiter when the window is inactive. I use FPS limiter from my graphics card control panel and suggest you to use it too, it works much better and smoother.
It's just my pack for regular use. I add mods on my own but I also want to share this pack because it seems cool in general :)
The aim of this modpack is a stable vanilla game with maximum performance (with no visible quality degradation) and worthy visual or useful additions.
Important
If you have problems with booting this modpack (usually on Windows 10), try disabling Mica mod.

Not Just Fast 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.

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 Not Just Fast without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). 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.
