i figured i'd post something where i'm not begging for answers for a change.
i read a post on this forum from someone who had discovered that minimizing the patch (in windows) saved somethng like 40% cpu but i was skeptical having just switched over to linux, but i needed to crank up the windows version and my vst rig for a number of shows this weekend. this system usually hovered around 90% cpu but for this show i also have a GEM viz that i figured i'd either not use or brace for the core meltdown. but i decided to test this theory and it works! i am able to run NI Kore and the GEM viz and the cpu hovers around 60%!!
just thought I'd share this tidbit. its has saved my ass and made my day.
