Velocis

Velocis skips the rendering work you can't see, then holds a higher FPS target by trimming the detail you're least likely to notice — and gives it back when there's headroom.

Client-side only. No gameplay changes.

Features

• Occlusion culling for mobs, chests, signs and banners fully hidden behind walls
• Screen-size LOD — shadows, armor and held items skipped on mobs too small to see
• Sign text LOD for far-away signs
• Particle budget under heavy load (damage, crits and explosions are never touched)
• FPS-target governor — the Balanced preset aims for +35% over your own PC's frame rate, cheapest-to-notice detail first
• Render scale + sharpening with the HUD kept sharp (1.20.x – 1.21.1)
• Laptop GPU check — warns when Minecraft runs on integrated graphics by mistake
• Background FPS limit when the window isn't focused
• Presets, settings screen, /velocis commands and a built-in benchmark

Measured

RTX 5050 laptop · i7-14650HX · 1080p · Minecraft 1.21.1 · median FPS, same world and camera path

Busy bases, farms and particle-heavy scenes gain the most; plain terrain gains less.
