for example:
./cgminer (connection parameters) --gpu-engine 1130 --gpu-memclock 1900 --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256
I get:
cgminer: --thread-concurrency: unrecognized option
cgminer: --shaders: unrecognized option
I run CGMiner w/o this options - for 30 second he worked(but on very low speed for my cards) and accepted 4 shares, and then speed falls to 0 and no more shares accepted..
P.S. Sorry for my bad English.
