Why does RetroArch make my SNES games look so low-resolution?
In Retroarch, I am using the glcore driver and the BSNES-HD-BETA Core with the default settings. I've tried making many changes to aspect ratio, custom scaling, custom screen resolution, shaders, etc. with no luck.
My games look pixelated and when I watch others play online, their games look higher resolution. See screenshots.
What settings can I use to make my games look as good as youtube examples of snes games? My screen is on the left. Notice the pixelated edges.
The image on the left is how the game looks by default. The image on the right has a shader applied. This is not necessarily a "higher resolution" - in this case, it looks like a simple blur has been applied to reduce pixelation.
Retroarch has a ton of shaders. You can find more examples and documentation https://www.retroarch.com/?page=shaders . Try out a bunch of them and see which ones you like best.
