yeah, with windows,
Affinity changer is what maxes the 8 threads' of fahcore_a1 efficiency http://distributed.org.ua/forum/inde...showtopic=1149
I'm using it to run dual smps in vista64 with one gpu2 client...

last time I tried it in xp, gpu wouldn't play nice with it... because I had to isolate fahcore_a1 to 3 cores, and affnity changer was written to use all 4 cores.
