• Performance Optimizations: l_aggy

Features

(All information and statistics is based on V1.3)

• Ultra-optimized for integrated graphics (iGPUs)
• 40%+ improvement on Balanced compared to MakeUp-Ultrafast with all effects off
• Color grading and biome‑specific lighting for all dimensions.
• Cinematic post‑processing: bloom, sharpening, tonemapping, TAA, motion blur, film grain, vignette.

To-do

1. More benchmarking
2. Adding features (Can't really optimize more)
3. Bugfix some features

Performance Profiles

• iGPU (8 Chunks) tested on i5-4570 (HD4600) on CachyOS

• dGPU (24 Chunks) tested on R9 8940HX (5060 Laptop=4060 desktop) on Windows 11

• Choose a profile in shader settings that matches your hardware:

Profile	FPS (iGPU)	FPS (dGPU)	Description
ULTRA_PERFORMANCE	190+	440+	Maximum FPS, minimal effects
PERFORMANCE	190+	??	Good balance for iGPU
