well, that's the other thing.. my 1280x480 loops are very long (sometimes even 2 minutes.) and that's why i can't use soo many layers with my notebook and TH2G, and also i'm a big fan of blending modes so i don't dissable global effects....i use 1920x480 too, but than i can use only 3-4 layers..
Of course with i7 processor, SSD and 2 graphic cards u can do 50fps anytime. But i travel a lot and do outdoor festivals and i don't wanna carry a desktop around...I try to use as much of my own images as it's possible, but i also "sample"

or buy anything i like, and goes with my images...

In the show posted above are mostly my own images shot in NYC...
u can check a show i did for international film festival with DH2G 1600x600 with 5 minute long DXV viedos and triggering audio samples too, which was also possible thx to Avenue and all with really low bugget... for big bugget and resolution shows i use Dataton Watchout or Ventuz
