Nick Crow Lab "7170_Lead" v.1.2 for Win and Mac VST & AU (FREE)

As the older version, is fat-motherfucking resources eater.
Only one instance and takes 60% of CPU at my 5 years old pc.
Why such big difference with 8505 which only takes 3%?
 
Thanks for the awesome plugin! Any chances for 7170 to include HQ switch..? Works great with i5, but consumes a bit too much CPU with my old N950 laptop =(
