ShaderBeam: Bringing CRT Motion Clarity to the Windows Desktop
A new open-source application titled ShaderBeam has been released by mausimus, aiming to bridge the gap between modern high-refresh-rate displays and the distinct motion characteristics of classic CRT monitors. Developed by Mausimus, the creator of the popular CRT shader tool ShaderGlass. ShaderBeam is being introduced as a “sister app” that focuses specifically on motion clarity through advanced simulation.
The Technology Behind the App
The core of ShaderBeam is built upon Blur Busters’ CRT Beam Simulation technology. Unlike standard filters that simply add scanlines or static masks to an image, this simulation mimics the way a cathode-ray tube’s electron beam scans across the phosphor screen.
By leveraging high refresh rates, the software can insert frames or manipulate the display output to reduce the motion blur typically found on modern LCD and OLED panels. This allows users to re-experience the fluid, crisp motion that was a hallmark of retro hardware without requiring a physical CRT or external scaling hardware.
Technical Requirements
To achieve the intended effect of true CRT motion clarity, the application relies on the overhead provided by modern monitors. The developer and early testers highlight the following requirements:
- Minimum Refresh Rate: A display capable of at least 100Hz.
- Recommended Refresh Rate: 240Hz or higher is ideal to provide the necessary headroom for the simulation to operate smoothly.
- Operating System: Windows Desktop.
Open Source and Accessibility
ShaderBeam is free and open source, making it an accessible alternative for enthusiasts who want to enhance their retro gaming or desktop experience on PC. By handling the processing internally, it eliminates the need for additional hardware like specialized upscalers.
For those interested in exploring the code or downloading the latest release, the project is hosted on GitHub:

The application continues the developer’s work in the “Shader” ecosystem, providing a dedicated tool for those who prioritize the authentic “feel” of motion in addition to visual aesthetics.
