Use ShaderGlass with ScummVM Adventure Games

ScummVM is among the documented compatible applications; ShaderGlass can provide a separate CRT or smoothing layer on top of a captured window.

Before you begin

Use Windows 10 version 2004 (build 19041) or Windows 11 and a DirectX 11-capable GPU. Confirm the source window or capture device works without additional post-processing. The exact labels can differ between ShaderGlass versions and operating modes.

Step-by-step workflow

1. Run a classic adventure title in ScummVM and select a consistent screen size.
2. Attach ShaderGlass to the target output using a supported capture arrangement.
3. Compare CRT, smoothing and sharp pixel-oriented presets.
4. Check subtitles and cursor readability, then save the final profile.

Important details and limitations

Subtitles are important in adventure games, so avoid filters that obscure thin fonts.

ScummVM display options and ShaderGlass overlays act at different stages of the picture.

Test both static backgrounds and animated scenes before deciding.

How to verify the result

Compare the processed scene with the same source shown without ShaderGlass. Watch for clipping, unexpected color changes, black regions and input lag. Keep one parameter fixed at a time while troubleshooting. For version-dependent settings, refer to the developer manual instead of relying on old screenshots.

Questions and answers

Is ShaderGlass part of ScummVM?

No. It is a separate overlay for visual effects.

Can a CRT filter reduce subtitle readability?
