The author embarked on a project to create a text-based file manager using Go, inspired by classic programs like FAR Manager. After encountering challenges with input handling in Windows' console mode, they shifted focus to output rendering. They compared various methods for drawing text on the screen, specifically looking at both console and graphical methods. They found that the newer VT mode for console output was slower than the traditional WriteConsoleOutputW method. After realizing Go wasn't suitable for efficient rendering, they transitioned to C# and tested three graphical rendering paths: GDI, DirectX, and Vulkan. Benchmark results revealed all methods performed poorly under heavy stress tests, but DirectX outperformed the others in realistic scenarios with white text on a black background. When exploring caching techniques by creating textures for each character, they noted a significant speed increase during stress tests. However, this approach reduced flexibility and performance during regular use, as it limited the ability to optimize text drawing. The findings indicated that while caching can boost performance under specific conditions, direct text drawing with DirectX remains the most efficient method for a balance of speed and flexibility.
