I've just started using SadMan Sudoku, and noticed that the CPU usage is sometimes very high. Why is this?
A. Sudoku is busy building up a library of puzzles. It does this in the background so that there's always a puzzle ready when you want one. Once the library is full, which may take several hours, it will stop. You can:
- Leave it running unattended for a while to give it a chance to fill its library without the fan bothering you.
- Disable background creation of puzzles. View -> Options -> Options tab -> Create puzzles in the background. But if the library is empty when you want a new puzzle, you'll have to wait while one is generated.
- View some stats on the library to give you an idea how much longer it will be annoying you. View -> Library statistics. The library is set to hold 2700 puzzles, split across the various grades, works out at 300 puzzles per grade.
Note: this shouldn't happen from version 3.2 onwards (released 10 October 2008) as Sudoku is now installed with a pre-built library containing 2700 sudokus. As you play or print the sudokus, more are automatically created to replace them.
