Strioline
An experimental, unofficial Vulkan-based variant of Fabulously Optimized that replaces the standard rendering stack with VulkanMod while keeping as much of FO’s performance and quality-of-life design as possible.

About this Modpack
Strioline
This project is an experimental Vulkan-based variant of the well-known Fabulously Optimized modpack.
It aims to preserve as much of the original Fabulously Optimized (FO) experience as possible while replacing the traditional OpenGL/Sodium rendering stack with VulkanMod. The goal is to explore potential performance improvements and alternative rendering paths on supported systems.
About Fabulously Optimized
Fabulously Optimized is a community-driven modpack focused on:
- High performance
- Visual improvements
- OptiFine parity features
- Stability and quality-of-life enhancements
This project would not exist without the original FO team and their excellent work.
All core design philosophy, mod choices (where compatible), and configuration direction originate from the FO project.
This is not an official FO release and is not maintained by the FO team.
What’s Different in This Edition
This variant replaces FO’s standard rendering stack with:
- VulkanMod as the rendering backend
- Removal of mods that are incompatible with Vulkan rendering
- Adjustments to maintain stability under a non-OpenGL renderer
Because VulkanMod fundamentally changes how Minecraft renders graphics, some visual or performance-related FO features may be missing, altered, or behave differently.
Experimental Status
This modpack is experimental.
You should expect:
- Rendering bugs
- Visual glitches
- Feature regressions compared to standard FO
- Incompatibility with certain resource packs, shaders, or rendering mods
This pack is intended for users who are comfortable testing, troubleshooting, and reporting issues — not for players seeking a fully stable experience.
Compatibility Notes
Due to the use of VulkanMod:
- Shader support differs from standard FO (Iris/Sodium shaders are not used)
- Some rendering enhancement mods from FO are intentionally removed
- Visual parity with the main FO pack is not guaranteed
If you want the fully supported and polished experience, please use the official Fabulously Optimized modpack instead.

How to Set Up a Strioline Server
Order Server
Choose at least 4 GB RAM (6 GB recommended for Strioline). Based on player count: per 8 players.
Install Modpack in Dashboard
Open the modpack browser in the dashboard, search for "Strioline" and click "Install". The fabric loader and Minecraft 1.21.5 are configured automatically.
Start Server & Play
Start the server – all mods are loaded automatically. Share the server IP with friends and play together!
Frequently Asked Questions
Strioline 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 Strioline 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 Strioline without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.5). 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.
Strioline 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.
