Performance History

Performance History

The original Blitz3D is the baseline at the top, then one row per version tag of BlitzLLVM, built and benchmarked on its own with the short benchmark set (benchmarks/history_commits.py --tags, 3 runs, mean ± standard deviation). What changed in a version is in its release notes. 📈 is better, 📉 is worse and ➖ is the same as the baseline (a change under 3%, or one under two standard deviations of the difference, counts as the same). Last updated 2026-11-01.

Machine

CPU	AMD Ryzen 7 9800X3D, 16 threads
GPU	NVIDIA GeForce RTX 4080 SUPER
OS and version	Windows 11 Pro 24H2 (10.0.26100)
RAM	64 GB DDR5-6400
VRAM	16 GB
Renderer / converter	Vulkan, NVIDIA driver (native)

The baseline, the original Blitz3D 1.118, does no optimization at all and relies on legacy Windows libraries (DirectX 7, DirectInput, DirectPlay, DirectShow), so the rows compare what a program does, not how the two are built. Numbers of different machine definitions can not be compared. Every program runs windowed, one after the other, with nothing else running.
