Meeting a Slow Doom

This directory provides a branchless, mov-only version of the classic DOOM video game. This is thought to be entirely secure against the Meltdown and Spectre CPU vulnerabilities, which require speculative execution on branch instructions.

You look at the example screenshot, and see it’s basically the game’s initial view. A bit lazy on the part of the author? Well, no…

The mov-only DOOM renders approximately one frame every 7 hours, so playing this version requires somewhat increased patience.
