About this Modpack

This modpack only contains optimisation mods.

The tests where done on this hardware:

CPU: i5-1235u.
iGPU: Intel Iris Xe Graphics
RAM: 16GB.
The operating system is Windows 11 Pro.
I did not used V-Sync.

Vanilla: min 65, av 105, max 115

My modpack: min 100, av 210, max 260

Note:

When you first create a world, you might see a low number of FPS for a few seconds, in my test this did nit lasted more than 10 to 30 seconds. This seems to depend on your computer.

This pack uses Vulkan, which changes the Minecraft rendering engine from OpenGL to Vulkan. This means that many Minecraft mods won't work with it. Please check the Vulkan mod Discord server for an updated list of incompatible mods.
If you're looking for a modpack that has better mod compatibility please take a look at my other one: https://modrinth.com/modpack/optimization-axo/.

Important Note

I licensed the project under GPLv3, but it's important to remember that every mod in this modpack has its own license. You should respect these licenses first. I'm not directly involved with any of these mods. If you have any problems or complaints, please contact me on Discord (my username is axolotl.c).

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 Axo's Optimizations [Vulkan] 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.

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.
