I really enjoyed the author's technical deep-dive and approach to debugging performance issues. Mild spoilers for anyone who hasn't played Riven, but the method for fixing Gehn's faulty linking books is a perfect analogy for the author's more counterintuitive performance optimizations.

While I don’t have a write-up as detailed as this one, I spent a month on a similar journey optimizing an animated ASCII art rasterizer. What started as an excuse to learn more about browser performance became a deep dive into image processing, WebGL, and the intricacies of the Canvas API. I’m proud of the results but I’ve annotated the source for a greater mind to squeeze another 5 or 10 FPS out of the browser.

Maybe it’s time to brush up on those WebGL docs again…
