+## Rain/Matrix rendering is slow on Windows
+
+- **Description:** The rain and matrix terminal effects are significantly slower on Windows, especially with high density settings.
+- **Cause:** This is due to the way Windows handles terminal display updates, which is inherently less efficient than on Unix-like systems.
+- **Status:** Not fixable in Bash; this is a limitation of Windows terminal design.
+- **Workaround:** Lower the density parameter for better performance, or use a Unix-like environment for optimal speed.
