Smart Gamma 0.1.2

Smart Gamma is a single-pass GPU shader filter plugin. It samples scene luminance, applies gamma/brightness/contrast/saturation boosts when captures drop below a configurable threshold, and fades back as soon as things brighten up.



Key features

• Automatic brightness guard: Observes average luminance, applies a threshold + hold timer, and only engages when the scene stays dark long enough to justify extra gain.
• Single-pass GPU work: All adjustments stay inside one shader with no per-frame heap churn and no readbacks larger than 32×32, so the filter typically costs ~0.1 ms per frame at 1080p.
• Smooth transitions: Configurable fade-in/out curves and debounced thresholds prevent flicker during HUD flashes or sudden highlights.
