Does anyone know why heshreyt fell on r9 280x. Was 5.5 MH/s now, about 4.3 MH/s.

Don't chenge bat file -thorcoinminer -o stratum+tcp://thor.zeuspool.com:3336 -u ***.* -p *--scrypt --Nfmin 4 --Nfmax 30 --StartT 1393167677 -I 15 --gpu-fan 100 --gpu-vddc 1.144 --gpu-engine 1070

be sure to change that nfmin to 5... i forget what time.

changed, did not help(

It fell because of the increase in the N Factor. Read the OP and then read about what is scrypt-jane (chacha), n factor, timestart and how it works.
In short terms the higher the n factor the lower the speed of your hardware because of the change in the requirement of memory for the calculation increases thus reducing performance
