cgminer ignores my startup bat

[N[e]wBie]

Hello, just a simple question.. my cgminer is ignoring my startup bat and runs with its "own" settings. I don't have a .conf file.
Trying to run a 280x with these settings in the bat:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://middlecoin.com:3333 -u user -p x
-I 13 -w 256 -g 1

And, it starts up with intensity = 8, and I am getting 6-35 KH/s with my 280x. It sometimes works with very similar settings, it seems to be VERY random. What is going on? Thank you!

Try adding a --thread-concurrency 8192    or --thread-concurrency 22400 for a 280x  seem to get different and comparable results using both.

Also, try running your .bat file with -n  and a PAUSE at the end of the file in order to see how your gpu's are being read.  you may need something like --gpu-platform 1 -d 0 added to your .bat file
