Quick answer

Which FrostClient release should I use?

Updated 3 days ago
Latest stable file Frost Client 1.21.11 - Vulkan
Game version 1.21.11
Loader Fabric 0.19.3

Frost Client 1.21.11 - Vulkan is a complete pack release for 1.21.11 with Fabric 0.19.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 79 mods in this pack file.

Pack setup

How should I set up FrostClient for players and a server?

Use Frost Client 1.21.11 - Vulkan as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Frost Client 1.21.11 - Vulkan
Dedicated server setup Match Frost Client 1.21.11 - Vulkan
Pack loader Fabric 0.19.3

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Referenced mods 79
Client only 0
Server only 0
Not labelled 79

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for FrostClient?

Frost Client 1.21.11 - Vulkan. Change the pack release and its contents or setup may change too.

79 mods in this pack file

The selected pack release is Frost Client 1.21.11 - Vulkan. That file is for Minecraft 1.21.11 with Fabric 0.19.3. It contains 79 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

What kind of pack is FrostClient?

title


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.
  • 🎯 HitColorPlus & Crosshair Addons — clean hit feedback and a fully customizable crosshair.
  • ⌨️ 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.
  • 📦 Chest Tracker & Shulker Box Tooltip — see what's inside without opening it.
  • ⚙️ Mod Menu + YACL / Cloth Config — every mod's settings in one clean menu, in-game.
  • 🖱️ Smooth Scroll & Multi Key Bindings — the small stuff that adds up.

Customization & Visuals

  • 📐 ReScale — change your aspect ratio in-game, no extra software.
  • 👥 Built-in friend list — add friends and play together, no server to buy or host.
  • 🧣 Better Capes / Wavey Capes — free custom capes, no third-party service.
  • 🔭 Freelook, Zoomify, toggleable Motion Blur, Skyboxify, Gamma Utils — camera and visual tweaks that matter for PvP.
  • 🎨 A custom branded main menu (ImproperUI), not vanilla's.
  • 🖼️ Comes bundled with a few ready-to-go resource packs, including a custom Zipp CPvP pack, a lightweight "potato" pack, and a dedicated PvP crosshair pack.
