Finally got scrypt working with bfgminer with help of Zanatos666, thanks again for helping me find a solution
People who have problems getting scrypt working you need to mess around constant with the "thread-concurrency" leave all other parameters away besides --scrypt and the needed pool parameters and the "thread-concurrency".
Do NOT add worksize, shaders, lookup-gap or vectors let the program do it when it has started and runs you can write a working config from within bfgminer
I advice you to make use of any stratum pool because this will somehow get it to make the necessary .bin file as long as that is not created you will not get it running at all
Zanatos666 his changes to the .conf gave me the idea to tinker with that parameter and i left all other parameters away because the old .conf did not start in any way. So i did enter in the concurrency "8192" but it did not start so i changed it to the max known setting for 7970 gpu "22400" and poof it started
I am now experimenting with all of them to see when it fails and try to find the best hash power with changing them one by one, if a scrypt.......... bin NOT has been made try set some of the parameters to set to "0" this seems to make the miners fill that parameter by itself
Before the mess started my scrypt was having the following settings and failed to run all of a sudden completely even though it has worked for a very long time :
"vectors" : "1",
"shaders" : "2048",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "21712",
now it looks like this :
"vectors" : "1",
"shaders" : "0",
"worksize" : "0",
"lookup-gap" : "0",
"thread-concurrency" : "22400",
