FPSMaster

What FPSMaster does FPSMaster bundles a large set of PvP-focused utilities and performance tweaks into a single client-side mod. It targets players who want the convenience of an all-in-one PvP client without installing a custom launcher or switching away from their existing mod setup. The feature list covers toggle sprint, old 1.7 animations, auto-GG chat messages, fullbright, particle and sound customization, on-screen indicators for CPS, FPS, and inventory status, a built-in music player, dynamic blur effects, realistic item physics, and free cosmetic items. The project describes itself as a modular alternative to full PvP clients such as Lunar or Badlion. ## Who it suits The mod is aimed at competitive PvP players who run Forge or Fabric and prefer to manage their own modpacks. Because it's client-side only, it works on any server that allows the listed features; the server side is explicitly unsupported. Players who want a lightweight way to add sprint toggles, visual aids, and quality-of-life tools without a separate client download will find it a fit. ## Verified capabilities - Toggle sprint, old 1.7 animations, auto-GG, fullbright, particle and sound customization, on-screen indicators (CPS, FPS, inventory status) - Built-in music player - Dynamic blur effects - Realistic item physics - Free cosmetic items - Vanilla performance optimizations described as targeting entity occlusion culling, particle frustum culling, model batching, and string rendering cache - 50-plus features total, all packaged in one mod ## Compatibility and requirements - Mod loaders: Forge and Fabric - Minecraft versions: 1.8.9, 26.2, 1.21.8, 1.21.11, 1.21.1, 1.20.1, 1.19.2 - Client side: required - Server side: unsupported - License: GNU GPL v3.0 only The repository notes that the Edge branch targets Forge 1.8.9 specifically, while newer versions are developed under a separate FPSMaster-Nova codebase.
