Month: 2025-01 Key features delivered: - Enhanced GPU Resource Dumping for Debugging: Adds a command-line option to dump GPU resources before draw calls and limits dumping to modifiable DirectX 12 resources, improving debugging precision by focusing on relevant resources. - Codebase Formatting Cleanup: Applies consistent formatting across the codebase to improve readability and maintainability. Major bugs fixed: - Stabilized resource dump workflow: dumps now occur after draw calls and only for modifiable DX12 resources to reduce noise and improve debugging signal. Overall impact and accomplishments: - Improves debugging efficiency and reduces workflow noise; accelerates triage and issue resolution; improves code maintainability via formatting. Technologies/skills demonstrated: - C++ tooling and DirectX 12 resource management; code formatting standards (clang-format); Git-based development workflow.
