Settings

Optimum adds an Extra tab to the client settings dialog. All toggles default to ON.

Switches

Setting	What it controls	Default
Limit Background FPS	Cap to 30 FPS when the window loses focus	ON
Smooth Frame Pacing	Hybrid sleep/yield/spin frame limiter	ON
Skip Distant Shadows	Skip shadow draws beyond the distance threshold	ON
Skip Distant Collisions	Skip repulsion physics beyond the distance threshold	ON
Scale Light Range	Scale held-item light radius by view distance	ON
Reduce Distant Animations	Reduce tick rate for distant animated block entities	ON
Skip Foliage Far Shadows	Skip vegetation in the far shadow cascade	ON
Throttle Wind Updates	Cache wind speed for 4 frames instead of every frame	ON
Reduce Distant Particles	Skip particle emitters beyond 48 blocks	ON
Simplify Distant Chiseled Blocks	Render far chiseled blocks as solid cubes	ON

Sliders

Setting	Range	Default	Unit
Shadow Distance	20-200	80	blocks
Collision Distance	16-128	64	blocks
Chisel LOD Distance	32-256	48	blocks

Non-Configurable Optimizations

These run unconditionally because they produce identical output to vanilla with zero tradeoff:

• Ambient sound position gate (skip when stationary)
• Fly sound volume deduplication (skip below 1% delta)
• BlockPos reuse in particle ticks
• Mat4f.Multiply inlining (compile-time)
• Animation check reorder (distance before frustum)
• Name-tag frustum reuse (IsRendered flag)
• Entity render distance pre-cull
• Lock contention reduction (System.Threading.Lock)
• Server GC with DATAS
• Bilateral blur 7-tap shader
• Water foam 3x3 shader

Persistence

Settings persist to ModConfig/optimum.json in your data path. Each toggle and slider writes immediately on change. Removing Optimum and reverting to vanilla ignores this file.
