PeakOptimizer
A performance and stability mod for PEAK that improves frame rates, eliminates micro-stutters, and reduces CPU/GPU overhead.
What is this mod?
I originally made PeakOptimizer because playing in big multiplayer lobbies was turning our games into literal slideshows.
This mod focuses almost entirely on CPU, math, and internal engine cleanup. Things like moving voice and wind physics to background threads, and fixing laggy distance checks.
Works great with graphics mods
Since this mostly touches engine logic under the hood instead of modifying textures or reducing visual quality, you can safely use it alongside graphics mods, like HDPeak.
Features
- Multithreaded Physics: Offloads heavy background raycasts (voice chat obstruction, wind shelter) to worker threads.
- Zero-GC & Anti-Stutter: Eliminates GC allocation freezes during zombie targeting, and continuous physics checks.
- Multiplayer Optimizations: Fixes lag spikes in large multiplayer lobbies with many players.
- Hazard & Particle Fixes: Eliminates lava lag in The Kiln while keeping hazards working.
- Rendering & Shadows: Optimizes Citadel torch shadows, grass rendering, and fixes shadow acne on mountain terrain.
- World Culling: Pauses distant foliage physics.
