Unlike Yuzu’s brute-force approach, Ryujinx uses PPTC to cache translation rather than execution . Instead of saving the final GPU binary, it saves the intermediate representation (IR) of the shader. When you load the game, PPTC re-compiles the IR for your current GPU and driver. Loading is slower (because it has to re-compile the IR). The Win: You never get graphical corruption after a driver update, and the cache is portable between similar GPUs.
