# Testing Real-Time Performance in Graphics Projects When working on real-time graphics, shaders, or interactive visual experiments, performance testing is just as important as visual quality. FPS drops, unstable frame pacing, or GPU bottlenecks can completely change how a project feels, especially in browser-based or live-rendered environments. One useful approach is running controlled, repeatable benchmarks that focus specifically on shader load and real-time rendering behavior. Tools like [Volume Shader real-time FPS test](https://volumeshader.co/) are helpful for quickly validating how volumetric effects and shader complexity impact performance across different systems. This kind of testing is especially valuable during early prototyping, when you’re still deciding how far you can push visual fidelity without sacrificing responsiveness. Keeping performance checks simple and consistent makes it easier to document results, compare changes, and share findings with collaborators.
