Can MS Paint run Doom? (Yes)
↗
Doom has been made to run within Microsoft Paint by using the Windows clipboard to transfer each frame into Paint's canvas, achieving up to 35 FPS.
This demonstrates the extreme portability of Doom's code and the creativity of engineers in repurposing everyday software. For engineers, it highlights how even a simple application like MS Paint can be hijacked as a display device through clever use of system APIs, though the approach is impractical for real use.

DoomPaint uses the Windows clipboard to paste each rendered frame into MS Paint as a document edit, effectively turning Paint into a monitor.
The project was created by Mark Russinovich, CTO of Microsoft Azure, and includes sound and music support.
The game runs the original shareware Doom at up to 35 FPS, which is acceptable for 1990s-era gameplay.
THE READ
What elseif makes of it.
The novelty here is not that Doom runs on yet another device, but that it runs inside a program never designed for real-time graphics. MS Paint is a simple image editor, not a game engine. By using the clipboard as a frame buffer, the developer bypasses Paint's lack of a rendering API, but at the cost of high latency and system overhead. The 35 FPS achieved is surprisingly playable given the round-trip through the clipboard.
This project is a proof of concept rather than a practical gaming solution. It requires a specific setup: the original shareware Doom, MS Paint, and likely a Windows environment. The clipboard-based approach means every frame must be copied and pasted, which consumes CPU and memory resources. For a working engineer, this illustrates how system integration can be abused for unintended purposes, but also the limits of such hacks, scalability and performance are poor.
The fact that the CTO of Microsoft Azure created this adds a layer of credibility and visibility, but does not change the technical reality. It is a fun demonstration of Doom's legendary portability, joining a long list of unconventional platforms like printers and gut bacteria. However, unlike those, this one uses a standard Windows application, making it more accessible to anyone with a PC. The GitHub repository provides instructions, so curious engineers can replicate the experiment.
From a software engineering perspective, the key takeaway is the clever use of the clipboard API to bridge two unrelated programs. This technique could inspire other creative integrations, but it also highlights the security and stability risks of allowing arbitrary clipboard operations. The project is a reminder that even mature, simple software can be repurposed in unexpected ways, but such hacks rarely translate into production solutions.
