CRT Simulation in a GPU Shader Outperforms BFI
2024-12-25
Blur Busters has unveiled a groundbreaking CRT simulation algorithm for GPU shaders, offering superior motion blur reduction compared to Black Frame Insertion (BFI). Combining Mark Rejhon's CRT beam simulator with Timothy Lotte's variable-MPRT BFI algorithm, it delivers smoother visuals, especially on high refresh rate displays, even for legacy 60Hz content. The algorithm, available on Shadertoy and GitHub, boasts less flicker than BFI and is set to be integrated into RetroArch.
