: Write a small OpenGL program that intentionally creates a performance bottleneck (e.g., many draw calls or texture uploads). Then, use Perfetto to trace both CPU scheduling and GPU execution, identify the bottleneck, and implement an optimization (such as batching draw calls or using a more efficient texture layout). Document the improvement with before/after traces.
