Description

✨ 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.
🔑 Key Features
Performance & Rendering
- 🌋 VulkanMod + Beryl — a modern Vulkan render pipeline with frame smoothing on top of it.
- 🧵 C2ME, Krypton, FerriteCore, Noisium, ModernFix, VMP, BadOptimizations — chunk loading, memory, networking, and startup all optimized together, not in isolation.
- 👁️ EntityCulling & CullLeaves — stop spending frames on what you can't see.
- 🖥️ ServerCore — faster singleplayer worlds and integrated servers.
PvP & Combat
- 🏷️ TierTagger — see a player's PvP tier right next to their name.
- 💀 Totem Offhand Warning + Totem Highlight — never miss a totem pop again.
- 💣 TNT Timer — know exactly when it's about to go off.

- ⌨️ Key Overlay — on-screen keystrokes for clips and POV footage.
Quality of Life
- 🎙️ Simple Voice Chat — built-in proximity voice chat, no third-party app needed.
