Every modulespelled out

No vague grid of icons. Here is what actually ships in SourClient, how each part behaves, and the hardware it runs on. If a module costs frames, it says so, and it ships off by default.

Performance

Frames that don't quit

Three render tiers retune the whole pipeline in real time with one switch. They never write to your GameSettings, so your vanilla and OptiFine options stay exactly as you left them.

Illustrative, not a measured benchmark. Real frame rates depend on your hardware, settings, and the server; the gap between tiers is the point.

The modules

What's in the box

Keep scrolling. Each stop is one part of the client, everything ships in the free build.

Performance engine Native engine

A native performance engine, not a bundled mod. Occlusion culling by raycast and visibility graph, plus frustum culling, run off the render thread. Chunks mesh on priority workers with a rebuild budget and LOD. A background light engine and lightmap cache keep lighting off the hot path. Packet handling moves off-thread so heavy servers never hitch your view.

HUD editor HUD editor

Drag-snap every element, save layouts, and swap them per profile. Twenty-plus widgets themed to your accent. Zoom, custom crosshair, a clean scoreboard and tab, chat tools with copy and mention pings, a nick hider that survives tab and nametags, and fully custom chorded keybinds.

Custom capes Cosmetics

Upload any image as your cape, not a fixed library, rendered with cloth physics. A safety blur means nobody is forced to see what they did not ask for. In-world sync to other SourClient players ships with the account service. One accent themes the whole client, launcher and in-game together.

Hypixel tools Tab intel

Session stats, network level, and per-player readouts render right in the tab list, built in, not a paid add-on. Bedwars resource counts, item counters by category, a combo counter, reach display, potion and armor status, all as HUD widgets you place yourself. Optional urchin.ws cheater tags when you bring your own API key, off by default.

Launcher Launcher

Opens fast, launches faster, and gets out of the way. Clean instance management with per-profile mods, options, and HUD layouts. The importer pulls your setup straight out of Lunar, Badlion, and the vanilla launcher. It ships its own Java runtime, so there is nothing else to install. Drop your OptiFine jar in once and it is managed into every profile.

HUD widgets

Place what you want

This is how the in-game editor feels. Grab any widget and drag it around the screen. In the client every position snaps, saves, and follows your profile.
