Harmony 14 rendering - cpu only?

Does anyone know if the export/render frame for harmony is only cpu bound, and doesn’t use any gpu rendering? And if so what is more optimal: a cpu like 6600k or does harmony take advantage of hyper threaded cpu like 6700k? Or even maybe waiting on octacore zen?

The last project i did had a complex scene using blur/transparency/glow effect for a hologram and 1200 frames of it were taking an hour to render (and failed both times to produce a file, forcing me to render out as a png sequence).




Great, thanks!
