FrostClient
Frost Client is a clean, minimal performance modpack for 1.21.11 — the spiritual successor to FoxClient, rebuilt for modern Minecraft with more stability, more FPS, and zero bloat.
Quick answer
Which FrostClient release should I use?
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.
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.
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.
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.
About this project
What kind of pack is FrostClient?

✨
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.
