The number of processor cores that are used for OCR in FineReader PDF can be changed as follows:

1. In the New Task window, go to Files > select Options....
   Or in the OCR Editor, go to Tools > select Options....
2. In the Options window, go to the Other tab.

For FineReader PDF 15, the selected number of cores is applied to OCR in the OCR Editor and via direct saving from the menu File > Save as Searchable PDF in PDF Editor. By design, FineReader PDF 15 uses 1 core for background recognition in PDF Editor, including the recognition starting with the Recognize button in PDF Editor. For other recognition processes, FineReader PDF 15 uses N-1 cores from N cores available for the processor.
