About this Modpack

✨
Frost is a performance-first Fabric modpack for Minecraft — the spiritual successor to FoxClient, rebuilt from scratch with a modern mod stack, a Vulkan renderer, and zero unnecessary bloat. 72 handpicked mods, tuned for CPvP and competitive play, all preconfigured out of the box.
🌋 Having crashes on the Vulkan build?
- Vulkan support depends heavily on your GPU and drivers. If you experience crashes, missing rendering, or startup issues, visit our Vulkan support page: https://frostclient.eu/vulkan
💎 What to Expect
- ⚡ A real Vulkan renderer (VulkanMod + Beryl) alongside a standard OpenGL build — pick whichever runs best on your hardware.
- 🧊 A deep, purpose-built performance stack under the hood — not just "one optimization mod," but a whole tuned pipeline.
- 🥊 Built around CPvP: tier tags, totem tracking, TNT timers, and hit feedback baked in from the start.
- 🆕 Native support for 1.21.11, maintained going forward.

Frost Client Lite pushes performance even further — on average 100–400 more FPS than classic Frost, depending on your hardware. Subscribers also get an in-game badge, a special Discord role, priority tickets, and staff pings. Check it out at frostclient.eu/lite.

Frequently Asked Questions
FrostClient 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 FrostClient 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 FrostClient 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.
FrostClient 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.
