I swapped to Windows in order to see which speeds I could get.
Using the -i flag apparently the program doesn't run for me. But just running it without any flags but o and O I get 144 k/hash with my 560 TI. I am not sure I quite understand the -l flag. What would a good setting for that be to a 560 TI?
it's either -i 0 or -i 1, not just -i
144 kHash is OK for a 560Ti. try passing -l 32x4 as launch argument, this might get you a few kHash more. If you feel like experimenting, also enable -C 1 or -C 2. Some people get 5-10 kHash more.
