Ah, the cruel reality of GPU programming. In normal code, an if-else is just a simple branch. But on a GPU, where threads run in lockstep, if some threads take the "if" path and others take the "else" path, your fancy graphics card basically says: "Cool, I'll just run both paths and waste half my processing power." Thread divergence: where your $1200 graphics card suddenly performs like it's running on hamster power because one pixel decided to be special. And we all just accept this madness as "the coolest thing ever" while silently dying inside.
