CRT Simulation in a GPU Shader, Looks Better Than Black Frame Insertion

  • Mark Rejhon, in collaboration with Timothy Lottes, has introduced a new open-source algorithm for simulating CRT (Cathode Ray Tube) displays, available on Shadertoy and GitHub.- This algorithm reduces motion blur on 240Hz+ displays and offers a softer flicker compared to BFI (Black Frame Insertion), and has been integrated into the Retroarch emulator.- The simulation is compatible with LCDs and OLEDs, providing real-time and slow-motion modes, and is particularly effective for reducing motion blur in legacy 60fps content.
