RetroArch xsal Shaders: Official Documentation Summary

Overview

The official RetroArch documentation maintainers a page for the xsal shader family. That page lists the shader variants covered by the xsal group and shows a preview image for each one. The page also contains a Background section, a Comments section, and an External Links section, all of which the source document leaves empty apart from a link to the Slang Shaders repository.

Shader variants named on the page

The documentation page lists five xsal shader preset names. Each entry is accompanied by a preview image filename that matches the shader name, which is how the page presents the family visually. The exact names as they appear in the documentation are:

• 2xsal-level2-crt
• 2xsal
• 4xsal-level2-crt
• 4xsal-level2-hq
• 4xsal-level2

Reading the names

The names appearing in the documentation follow a visible pattern: a scale factor prefix (2x or 4x), the string sal, an optional level2 segment, and for some variants a crt or hq suffix. The documentation page itself does not explain what these segments mean, so anything beyond the literal names is not stated in the source and is not asserted here.

What the page does not cover

The source page has headings for Background, Comments, and External Links, but the collected content does not include body text under Background or Comments. The External Links section shows a link to the Slang Shaders repository. Because the page does not describe installation steps, menu paths, performance characteristics, compatibility, or expected visual results, this article cannot supply them either.

Reference listed by the documentation

The page's External Links section points to the libretro slang-sha repository, which is the upstream project for Slang shader presets. That link is the only external resource the collected page content records.

Summary for readers

If you are trying to identify which xsal presets exist before looking them up in RetroArch itself, the official documentation supplies five names and their preview images. Beyond that identification, the page offers no procedural guidance, so verified setup steps are outside the scope of this source summary.
