AI Summary

Addresses persistent frame-rate inconsistencies in feedback backgrounds, particle trails, and diffusion blur for consistent visual behavior.

Key Highlights

Feedback backgrounds (Cascade, Tesla, Mycelium) maintain consistent brightness across 30/60/120 fps.
Particle ribbon trails (Cleave, Tide, Vessel) now measure duration in seconds instead of frames.
Panorama's graticule brightness and smearing no longer vary with frame rate.
Ascend's afterglow speed is now frame-rate independent.
Diffusion blur now operates based on time (seconds) rather than frames.

Full Release Notes


### Fixed
- **Feedback backgrounds no longer change brightness with the frame rate.** The 14 effects
  that accumulate particles into a trail — Cascade, Tesla, Mycelium and others — settled at
  about half their intended brightness at 30 fps and double at 120. Measured on Cascade:
  47.7% spread across 30/60/120 fps, now 6%. Nothing moves at 60 fps.
- **Particle ribbon trails last the same time at any frame rate.** Cleave, Tide and Vessel
  measured their trails in frames, so a trail running 267 ms at 60 fps stretched to 533 ms
  at 30 and shrank to 133 ms at 120.
- **Panorama's graticule no longer brightens or smears with the frame rate.** Its centre and
  edge guides were drawn at a fixed strength per frame, and its echo drifted a fixed distance
  per frame, so the reference line the effect exists to provide got both stronger and wider
  the faster your machine ran. Brightness spread across 30/60/120 fps drops from 59% to 1%.
- **Ascend's horizon wake rises at the same speed on any machine.** The afterglow climbed a
  fixed distance every frame rather than every second, so it travelled twice as far per
  second at 120 fps as at 60. Brightness spread across 30/60/120 fps drops from 14% to 2%.
- **Diffusion blur is measured in seconds now**, so Protea's bodies, Sumi's ink and
  Polycephalum's network smooth at the same rate however fast the machine runs. Protea's
  brightness spread across 30/60/120 fps drops from 41% to 18%.

## Downloads

| Platform | File | Notes |
|----------|------|-------|
| **macOS** | `.dmg` | Universal binary (Apple Silicon + Intel) |

## Getting started

**macOS**: Open the DMG, drag Fosfora.app to Applications (or run directly). Signed and notarized.

**Linux / Windows**: Extract, run `fosfora` from the extracted directory. The `assets/` folder must be next to the binary.

## Requirements

- **GPU**: Vulkan (Linux/Windows) or Metal (macOS)
- **Audio**: Built-in mic or line-in for audio-reactive visuals
- **NDI®** (optional): [NDI® SDK runtime](https://ndi.video) for network video output
- **Video playback** (optional): `ffmpeg` on PATH for media layers
