About this Modpack
Valkaw

Maximize your Minecraft performance with the ultimate optimization modpack!
What is Valkaw?
Valkaw is a high-performance modpack forked from Sliwed Optimize. We're constantly updating it to squeeze out better frame rates and fix issues, ensuring the project keeps moving forward smoothly.
Core Features
We've focused on three main upgrades to make your game lighter and faster:
Fastest Performance HUD
Powered by Hudder, FlexHUD, and CustomHUD, this displays the stats you actually need without hogging your resources.
Smart Resource Manager
We use FerriteCore and "Put A Plug In it!" to keep your RAM usage in check. Plus, EntityCulling uses your CPU to calculate what you can see in real-time, skipping the rendering of anything hidden behind blocks.
OptiFine Features
Missing Zoom or Dynamic Lights? No problem. With WI Zoom and LambDynamicLights, you get those familiar features back, now running on the faster Sodium or VulkanMod engines.
Main Optimization Mods
Valkaw offers two different rendering paths depending on your hardware. Choose the version that best suits your system!
1. Sodium Edition (Standard)
The standard, highly compatible optimization route using the OpenGL API. Perfect for most users and supports shaders.
Click to expand the Sodium modlist
- Sodium: The absolute best modern rendering engine for Minecraft.
- Lithium: General-purpose optimization for game physics, AI, and block ticking.
- FerriteCore: Significantly reduces the memory footprint of the game.
- EntityCulling: Skips rendering hidden entities/tiles to boost performance.
- Iris Shaders: Seamless, high-performance shader support (the best OptiFine alternative).
2. VulkanMod Edition (Maximum Raw Performance)
A wildly powerful route that completely replaces OpenGL with the Vulkan API. Incredible for squeezing out the absolute maximum raw FPS. Requires Vulkan API 1.3.
Click to expand the VulkanMod modlist
- VulkanMod: Rewrites Minecraft's renderer to use the Vulkan API, drastically reducing CPU overhead and boosting FPS.
- Lithium: General-purpose optimization for game physics, AI, and block ticking.
- FerriteCore: Significantly reduces the memory footprint of the game.
- EntityCulling: Skips rendering hidden entities/tiles to boost performance.
- Beryl: A mod that provides shaders like Vibrant Visuals, created specifically to improve the realistic gaming experience with VulkanMod.

Frequently Asked Questions
Valkaw 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 Valkaw server really need?
Minimum 4 GB, recommended 6 GB for stable performance. per 5 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 Valkaw without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.2). 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.
Valkaw 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.
