Unlike native Switch hardware, PC emulators like Ryujinx don’t understand the game’s graphical effects upfront. When Link climbs a new cliff, uses Ultrahand, or summons a Zonai device, your GPU has to compile a new shader — a small program that tells your graphics card how to render that specific effect. That compilation takes milliseconds, but in gaming, milliseconds cause visible hitching.
Set this to Vulkan . It handles shader compilation significantly better than OpenGL for TOTK. ryujinx totk shader cache best
