no combination: some Shader are designed to be combined with others in mind and don’t look good on their own.no other resolution: some Shader require high resolution to look great, others are designed for low resolution in mind too.no motion: some Shader properties such as flicker or motionblur are not optimally pictured in still images.no performance test: some are slow and may require a modern pc, others are very fast and optimized for low power devices.n o configuration tweaking: only default settings for the Shaders from RetroArch are used.no overlays or borders: Shader with borders are ignored.no other type of Shaders: only CRT type of Shaders that come as a default with RetroArch are included.In Final Fantasy 7 What has not been compared Bilinear filtering is disabled globally and no other filter is used in the core settings.Īs a consequence of these resolution settings some black borders on top-bottom and left-right on the screen will be visible, because the image is not stretched to fill entire screen.This will stretch the image generated by the core, which is what happened on real machines connected to the TV. The output image of the core is set to 4:3, because CRTs had this format.The image scaling of the cores are all set to integer type, which means that no uneven number of pixels are added and depends on the original resolution.4k is probably the optimal resolution, but I don’t have such a screen. Some Shader require high resolution and won’t work on lower. My desktop and emulation resolution is set to 2560 x 1440, which allows me to use basically any Shader.My setup and what has been compared My resolution setup This article is about CRT based Shaders only, ignoring handheld or other types such as painted look. Thanks to the integration into RetroArch, Shaders can be utilized by most, if not all, cores. Nowadays we have a lot to choose from advanced solutions. Shaders are much more sophisticated and allow realistic and complex filters rendered on the graphics card. This aspect has to be simulated in a different way. Games on a CRT TVs and monitors just look drastically different than on modern LCD or LED screens with fixed pixel sizes. But there is a missing piece in that equation: the output to a screen device. We have come far when it comes to accurately emulating classic game consoles and computer systems. With the advent of Shaders, this problem was solved. However, the result was not very accurate and often quite taxing on the CPU. Nintendo/Snes logos by Dan Patrick and David Pustansky.In the early days of Emulation, simulating CRT characteristics was achieved by filters that manipulated the produced game image before showing on the screen.Overlay config created with the RetroPad editor by.Special thanks to reddit user Kuroiryuu for the dark theme idea,Īnd help in color and font optimizations.(square displays like crt tv’s, vga monitors, lcd panels, etc.) Otherwise you’ll get displaced controls. Set the “AUTO SCALE OVERLAY” option to ON in non wide displays.Otherwise set the video scaling manually to fit your device display. Set the screen scaling to 4:3 in a 16.9 display to get a fullscreen perfect overlay fit.Use Vulkan or any Open GL driver (Direct X drivers are buggy with animated overlays).In-screen bezel removed (won’t interfere with shaders).(set the “AUTO SCALE OVERLAY” option to ON for non wide displays) No more black empty sides on ultra wide displays. Fixed flashing non animated elements when clicked/touched.
