The Ivanhoe RAR file that I downloaded from http://www.chesslogik.com/downloads/IvanHoe_999957a.rar has engines under each of three folders: default, popcnt, and prefetch.
Which one should I use? What is the difference?
Thanks

The default should work on most hardware. The others might be slightly faster on computers having the popcnt and prefetch instructions (and not work at all otherwise).notyetagm wrote:The Ivanhoe RAR file that I downloaded from http://www.chesslogik.com/downloads/IvanHoe_999957a.rar has engines under each of three folders: default, popcnt, and prefetch.
