More games are needed, but it seems Dirty ACCA4 64-bit, with 2658 ELO points, is not an improvement regarding previous versions (Dirty 6J-22 2668).

I wish a better success to the next Dirty version!

Well, at least it didnt crash. It seems than more optimizations make it faster but unstable.

Thanks for your tests. It is pretty sure than won't be more Dirty versions
