Based on CRT Royale, this filter includes a lot of cool features: - Horizontal ringing (produced by low pass filters e.g. SNES video output) - CVBS / S-VIDEO / RGB filter modes - Accurate pixel perfect dimensions (for 1080 resolutions and up) - TV frames that reminds the 90's experience - PC monitor frame also available - New adjustable scale system to fix image size and overscans - Ambient lighting and rear LED simulation modes - Reflections over the screen borders - Nice bulged screen finish - Auto scales to any resolution, preserving 4:3 ratio - 3 shaders available: normal mode, fast mode and doubled outputs mode Glcore and d3d11 drivers supported at the moment.
