In a dense forest test, OptiLeaves 2.0.1 delivered 35% higher average FPS than Forge alone. Results were close to Cull Less Leaves Reforged and Cull Leaves, with pixel-identical screenshots across all three leaf optimizers in the tested scenes.
Tested on 14 October 2026 with MC 1.20.1 / Forge 47.4.10, a Ryzen 7 5800H and RTX 3050 Laptop, at 1080p with Fancy leaves and view distance 8. Each optimizer ran separately, without shaders or extra renderer optimizers. FPS and frame-time figures are medians of three independent runs.
This was a constructed forest stress test. Results will vary with hardware and modpacks, and small differences between optimizers may be measurement noise. The compilation and allocation rows are separate single-run controls; they measure summed task time and temporary Java allocations, rather than chunk-loading time or total memory use. See the test setup and full results for details.
