Rendering techniques specifically designed to preserve crisp pixel-art edges on modern high-resolution displays.
Pixel art was designed for CRT screens at specific resolutions. Blow it up to 4K with standard bilinear filtering and edges blur. Pixel-perfect rendering uses integer scaling, shader-based CRT simulation, and careful subpixel snapping to preserve the intended look. It sounds simple but gets complicated when the camera moves subpixel-fractions per frame, which is why many 'pixel art' indies accidentally look muddy.
Example
Celeste, Hyper Light Drifter, and Shovel Knight all ship with pixel-perfect rendering options. RetroArch's CRT shaders recreate scan-line and phosphor glow. Analogue Pocket's DAC outputs pixel-pure HDMI signals for vintage game authenticity. Unity and Godot both have dedicated pixel-perfect cameras.
Why it matters
Pixel-perfect rendering is a craft skill that separates loving pixel art from clumsy pixel art. It is increasingly tooled-for in engines, but still trips up many indies who ship games that look worse than their source sprites.
