Dr. Memory provides a "light" mode that detects fewer errors in order to gain performance. It does not detect uninitialized reads nor leaks. It does detect unaddressable accesses, invalid heap arguments, GDI usage errors, and warnings. Use the runtime option -light to use light mode.

To add leak checking to light mode, add the option -count_leaks after the -light option. This will identify all error types except uninitialized reads.
