About this Modpack

I got tired of OpenGL being OpenGL. So I built this.

VulkanMod core. Full engine swap — OpenGL 3.2 out, Vulkan 1.2 in. Not a wrapper. Not Sodium with extra steps. Actual renderer replacement.

Runs on Xwayland not native Wayland. If you're on X11 it'll work there too.

Probably works on Windows 11 (or 10).

The numbers

Tested on my daily driver:

FPS Vulkan Optimized Sodium Vanilla
AVG 2370 1405 1007
1% 1356 859 620
0.1% 1029 699 520
Power draw 52.7W 46.5W 44.5W
FPS/W (AVG) 44.97 30.22 22.63

+68% over Sodium. +135% over vanilla. And yeah, it pulls more watts — because it's actually using the GPU instead of letting the CPU bottleneck everything. It will probably more power efficient on vsync or fixed fps scenario.
see the Gallery for more information.

My rig

  • CPU: Ryzen 5 5600X @ 4.65 GHz
  • GPU: RX 9060 XT 16GB
  • RAM: 32 GB
  • OS: Alpine Linux 3.24
  • Kernel: 7.1.3-0-stable
  • Display: KWin (Wayland) → Xwayland
  • JVM: -Xmx6G -Xms6G -XX:+UseZGC -XX:+AlwaysPreTouch

Note: This test is using Prism Launcher on flatpak environment. You will probably gain more fps if you run it natively.

What's in the pack

VulkanMod. That's it for rendering. No Sodium, no OptiFine, no Canvas — they're all OpenGL rewrites and they fight with VulkanMod.

Everything else is curated for compatibility. No bloat. If it doesn't work with VulkanMod, it's not here.

Heads up

  • Shader packs won't work. VulkanMod's shader support is improving but it's not OptiFine.
  • Fabric only. No Forge version, don't ask.
  • If you're on NVIDIA, your mileage may vary. AMD's where this shines.

That's it. Download it or don't. The numbers are above if you need convincing.

How to Set Up a Vulkan Optimized Server

1

Order Server

Choose at least 4 GB RAM (6 GB recommended for Vulkan Optimized). Based on player count: per 8 players.

2

Install Modpack in Dashboard

Open the modpack browser in the dashboard, search for "Vulkan Optimized" and click "Install". The fabric loader and Minecraft 26.1.2 are configured automatically.

3

Start Server & Play

Start the server – all mods are loaded automatically. Share the server IP with friends and play together!

Frequently Asked Questions

Vulkan 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 Vulkan 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 €5.2/month).

Can I add custom mods to Vulkan Optimized without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.1.2). 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.

Vulkan 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.
