About this Modpack

Glass Optimized: A satisfying vanilla experience.

Glass Optimized is a plug and play modpack based on Simply Optimized.

It features all the optimization from SO with added useful client-side mods, like Appleskin and Ok Zoomer.

The features:

  • Every performance mod from Simply Optimized.
  • Zoom mod (Ok Zoomer)
  • Hunger & saturation info (AppleSkin)
  • Cool-looking & useful HUD (StarHUD)
  • Shulker Box Tooltip
  • uku's Armor HUD
  • Xaero's minimap & world map
  • Slyde (Allows sliders to be dragged further than default)
  • Sodium Extra
  • Mod Menu & Reese's Sodium Options
  • Freecam (for cinematic screenshots & stuff)

Why I made this modpack:

Like many other people, I play a lot of Minecraft.

Often times, when I find myself on a different computer, or reinstalling my OS, I have to install a basic optimization modpack (Simply Optimized) and then I painstakingly look up & install all the QoL mods I want to use. (Appleskin, Ok Zoomer, Shulker Preview, etc.)

Then I wondered: "What if I could just install everything in one go?"

...and that's how I made Glass Optimized.

No, it's not unique. There's like a billion other modpacks that do the same job as this one. But from my hours of playtime on vanilla SMP's, this is the perfect combination of mods if you wanna have a great time.

No tacky menus, weird F3 screens or cash-hungry cosmetics mods. Very refreshing.

Wanna use it in your own project?

Sure. This would make a great base for any of your projects. Just give appropriate credit & respect Simply Optimized's license.

Frequently Asked Questions

Glass Optimized 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 Glass Optimized 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 Glass Optimized without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.6). 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.

Glass Optimized 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.
