About ShaderGlass

ShaderGlass is an overlay that applies GPU shaders on top of the Windows desktop and under Wine. It can display effects in a floating transparent window or full-screen, using a built-in RetroArch shader library for CRT simulation, upscaling, and adjustments such as blur and sharpen.

It supports saving and loading profiles, importing external .slangp/.slang shaders, and capture from a USB webcam or capture card source. It requires Windows 10 version 2004 or Windows 11 with a DirectX 11-capable GPU; use on Linux is through Wine/Proton with ScreenCast/PipeWire capture in clone mode only.
