About this Modpack

Over Vulkan uses a rendering mod called VulkanMod giving it better performance than Sodium. Normal Minecraft uses OpenGL for rendering. Vulkan is a different way of rendering a game, with waaay better performance. Expect around 500% more fps compared to vanilla (Dependent on your hardware).

Example: 200 Vanilla to >1000 Over Vulkan (render distance at 16 Vanilla and 32 for Over Vulkan)

Compatibility

Because this pack uses a different way of rendering, Vulkan, some mods wont be compatible. Mainly mods that adjust major visuals like Distant Horizons. Here is a list (note: this list is outdated, check the VulkanMod discord for an up to date list). It's compatible with servers.

Gameplay

No changes are made to the gameplay, because this pack is designed to be a foundation for your own pack or an optimized version of vanilla.

Requirements

To speed up chunk generation and general performance, a minimum of 2500-3500 Mb allocated memory is recommended. This is dependend on your render distance so playing with lower render distance allows a lower amount of allocated memory.
Installed Modpack > Settings > Java and memory > Memory allocated.

If you are experiencing stuttering, increase allocated memory or decrease render distance from the default 28!

Frequently Asked Questions

Over Vulkan 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 Over Vulkan 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 Over Vulkan 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.

Over Vulkan 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.
