Silksong reverse engineering and aggressive optimization claims

April 3, 2026r/gamedev

In r/gamedev, a highly upvoted Silksong code reverse engineering post sparked a pile-on debate about whether the findings are genuinely insightful or padded with misleading AI visuals and overhyped optimization.

I've spent 30+ hours reverse-engineering Silksong's code. Here's what I found :]
And found some genuinely impressive (and aggressive) optimizations.
The code itself is not very remarkable and all very standard for platformers (coyote time, input buffering).
Their “aggressive optimization” is just an if statement that checks if too much memory is being used, and then calls the unity functions to clear out memory.
It pains me to see this genuinely well made deep dive video with unique content downvoted, while the same repeat platitude posts keep getting all the positive attention on r/gamedev.
I broke down the exact frame-windows for Coyote Time and Input Buffering that make the platforming feel so responsive.
