Log history to file Enables hardware monitoring history logging to file. You may also control this option via the context menu of hardware monitoring window. Hints: - %PRODUCTNAME% saves history in native RivaTuner log file format. You may use either built-in viewer or RivaTuner to view log files recorded with %PRODUCTNAME%. - Hardware monitoring history logging is not absolutely free in terms of performance, some CPU time is required on each log update iteration to flush data to HDD. - You may disable user interface tooltips via tab in advanced properties.
