Probably someone else would wrote the xevan code,
xevan has been harvested for months with a descent profit. The profit is now gone. So the big farms that invested in the development of a private xevan miner are loosing alot of money right now. The profit used to be 3x per card. Feels like a robbery indeed...
Should we blame krlx? He just took the bounty that was there for him to be taken, and he doesn't share the profit with the real developers. Low moral, but not a criminal. The big farms just lost $5 a card per day and they have more than 100 cards.
The only way to keep the profit is to optimize the code. Again.
So as I said before. The "dirty" work is done. Now sp_ can make some tricks and release an optimised version.
But I think optimised version already exist - someone was mining with 7 rigs with avg speed of 58Mh/s - it is more than 10*1080ti per rig with krnlx version.
