Performance-optimization Memes

Graphics programmers know true suffering, and Vulkan is their personal tormentor. You spend hours hunting down why your render performance dropped by 1%, only to discover you accidentally declared a vertex attribute as vec2 (2 floats) when the shader was expecting vec3 (3 floats). The GPU just shrugs and does... something. Probably nothing good. For context: Vulkan is a low-level graphics API that gives you incredible control over the GPU, which also means it gives you incredible ways to shoot yourself in the foot. Unlike friendlier APIs that might warn you about type mismatches, Vulkan is like "sure buddy, read garbage memory, see if I care." The shader expects 3 coordinates but gets 2? Congratulations, your third value is now whatever random data happened to be in memory. Undefined behavior is the best behavior, right? The "pure hate" in the title is palpable. You can feel the developer's soul leaving their body as they realize their multi-hour debugging session was caused by a single missing float component. Graphics programming: where a tiny typo costs you your sanity and 1% performance on some random GPU from 2015.
