Been trying to find out more about this scrypt-jane news... Anyone got a link, info? Or, willing to write an overview of what it is?
scrypt-jane is a feature under development and some fearless people are trying it out. It is used in Yacoin and other Alt-coins and currently nVidia cards have an edge (around factor 2) over ATI cards. Hence the mining returns (payouts) are higher - and power costs are reduced also.
scrypt-jane currently does 32768 iterations and requires 4 MB of memory per hash. scrypt does 1024 iterations and requires 128kb per hash. This causes scrypt-jane to work most efficiently on mid range GPUs with 2-4 GB of RAM. High end nVidia GPUs are a bit faster, but only slightly.
my 2x Titans [are] getting 700.XX khash/s per GPU (1400-1430 khash/s for both cards).
Very good numbers! My GTX 780Ti only yield 540 kHash/s each (on Linux, with a mild BIOS based overclock).
