VWOMP!

DING!

CLACK!

TAK!

CLACK!

CLACK!

TAK!

CLACK!

DAAAD?!

The door wore Battlefield, Kong and Sonic. My kind of bouncers.

Daylight poured in like a code review. It found everything.

The idea rose off the notebook slow. It knew what it would cost me.

The bulb stayed lit. So did I. Somebody had to ship the damn thing.

I'm building tools for my dreams. I'm not dreaming for my tools.

pfx · game and render engine

From first scene to shipped game, or to finished film, in one engine.

Freaking fast, light and simple.

pfx is a game and render engine in Rust. Its documents are .pitofx files, TOML inside, and the editor and its inspector are there for placing and tuning by hand. pfx alone opens the window, pfx <file.pitofx> opens a document in it, and every command or flag runs on the command line without it. One tool from recipe to film.

Measured on an AMD Radeon RX 9060 XT and a Ryzen 9 9950X under Linux; the live numbers are the median of five runs. How and when each was taken is on its page.

01
An agent writes a .pitofx recipe

Claude, Codex, Grok or any coding agent edits the recipe through the CLI verbs, by dotted key; each edit writes the change and a fresh build back into the .pitofx in one atomic replace.

pfx newpfx setpfx getpfx add
02
pfx builds and renders

pfx build runs on the CPU with no clock and no randomness beyond the recipe's seed, so the same recipe gives the same bytes on any machine. The live renderer draws the scene; the path tracer and its denoiser render the stills and clips.

pfx buildpfx renderpfx clip
recipe-build.md
03
A path-traced film

pfx film cuts the clips, frame folders and cards into one film, with dissolves, pushes and whips and a true-peak ceiling on the master. The same script, seed and app give the same frames, byte for byte.

Manfred Manfred is built on pfx.
Inbox0 Inbox0 is built on pfx.

Kill it mid-frame, resume, get the same bytes.

Long renders survive a crash or a reboot. pfx writes every frame whole, checkpoints inside a long frame, keeps a ledger of each frame's fingerprint and renders the last finished frame again before carrying on, so a resumed render matches an uninterrupted one byte for byte.

How it's measured How resume works

Killed in: Frame 2
Same bytes: 8 of 8
Since: v3.1.1
