pfx is one engine from first scene to shipped game, or to a finished film. It draws a 4K scene live in 4.4 ms of GPU a frame (0 dropped in 1,200) and uses 0 ms when nothing moves. A GPU path tracer with its own denoiser renders 4K stills in about 6 s. An editor and a CLI work on the same files: change one value and get a file to ship in 63 ms (Godot: 2.34 s). An empty game ships at 29.1 MB. Linux, Windows, macOS. Open source, AGPL-3.0.

Could you build this?
No This is a custom game and rendering engine with a GPU path tracer, custom denoiser, real-time frame-budget optimization, and an editor. Building it requires deep graphics programming and years of engine-level engineering that vibe coding cannot substitute for.
What it would actually take: A real version needs a renderer written against Vulkan, DirectX 12, or Metal, with a physically based path tracer and a learned or edge-aware denoiser, plus a scene graph, asset pipeline, and a sync layer between editor and CLI. The hard parts are GPU performance engineering (frame-time budgets, dirty-tracking to reach 0 ms when idle) and rendering math. This takes a small team of graphics and tools engineers working over a long period.
