1080p displays can work for aperture grille emulation since less resolution is needed to render vertically aligned phosphors. The display you use for CRT-Royale should have at least 1440p of resolution to give a decent level of detail for slot mask emulation, though 4K (2160p) or higher resolutions are recommended. There's also various user-settings.h files in crt-royale-settings-files that enable/disable options for different GPU profiles. The author provided a preset for Intel users that compromises some functionality for compatibility. In particular, Intel iGPUs will struggle to run the shader and some may not even run in some cases. Discrete Nvidia or AMD video cards made in the last few years are recommended. Feel free to let me know if any of yall have any questions.CRT-Royale is a large and complex shader, so it will need modern hardware to run correctly.

Also be sure to update Reshade to the most recent version. Your mileage may vary if you're using a different res. I'm also rendering these shaders in 4k, which provides the best results. In the GTU shader, you will set the horizontal resolution to that of your monitor and the vertical one to the native vertical resolution of the game itself (in this example, Va-11 HaLL-a is 360p and Curse of the Moon is 240p).

In addition to the CRT Royale shader, you will also need the GTU.fx shader to add the scanlines, both of which can be found on github: CRT Royale GTU I minimized the sections I left on default (basically no blur, no border, screen geometry is flat). Feel free to change the gamma and contrast to suit your taste. They may be a little different from the screenshots I took like 2 years ago, but I tried to get it as close as I could. I've had a few people reach out to me asking about what settings I use my shaders in Retroarch, so I figure I may as well share them here.
