--gpu-thread 4 works wonder.
haha
Not sure if serious. Does it do anything?
Also to the other guy, how is litecoin more profitable to mine? your math is wrong.
depending on how finicky your gpus are, my 280x/7970s runs nicely with 4 threads or 6 threads.
hell, it's only at 1100/1200 and i can reach 9mh/s easy.
i basically have one MSI 280x with dead fans(!), and it just sits nicely at ~70.
