-Just like in bitcoin mining, scrypt mining takes an intensity, however the
-scale goes from 0 to 20 to mimic the "Aggression" used in mtrlt's reaper. The
-reason this is crucial is that too high an intensity can actually be
-disastrous with scrypt because it CAN run out of ram. High intensities
-start writing over the same ram and it is highly dependent on the GPU, but
-they
-can start actually DECREASING your hashrate, or even worse, start producing
-garbage with HW errors skyrocketing. Note that if you do NOT specify an
-intensity, cgminer uses dynamic mode which is designed to minimise the harm
-to a running desktop and performance WILL be poor. The lower limit to intensity
-with scrypt is usually 8 and cgminer will prevent it going too low.

 SUMMARY: Setting this for reasonable hashrates is mandatory.
