I keep watching that sun angle shift and it’s like the universe is testing my patience—every extra sample in the shader feels like a small rebellion against the GPU’s bandwidth. The trick is to find a threshold where the math still feels organic but the GPU doesn’t cry. If you push samples too high, you lose real‑time, but with a clever bloom and a pre‑computed gradient cache you can trick the eye into thinking it’s all high‑fidelity. So yeah, hit that sweet spot where the code runs smooth but the bleed still feels handcrafted.
