Crystallite is a simple modification of an old Crystal 3.1 by Joseph Ellis. Crystallite is made especially for fortress positions. It recognizes them better than Crystal 3.1, Crystal 3.2 and Crystal 4.0.

Crystallite 1.1a is the same engine as Crystallite 1.1 but it is faster: AVX2 (+4.3%), BMI2 (+5.8%), modern (+1.6%). The exception is base engine, where old 1.1 turned out to be faster than 1.1a by 7.5%, so this version remains unchanged.

I will do that once I return home from a job related assignment.

I will need to register there first as I am not yet a member of Vernon's forum.

It's not a pity. This net is intentional.
