Hi All!

I've just changed my graphics, now i have a EVGA Geforce GTX 780.

I just tried it, but I saw that during the ray trancing publish image, the GPU was not working..

Is that normal? (Is normal that ray tracing mode dont use my graphic card?)

(if I wrote something stupid forgive me, I'm trying to learn)

yes it's normal:
GPU= realtime rendering
CPU = rendering

unfortunately

Oh.. That is a bad day...

There's no way to improve the raytracing using my graphic card?

well not in showcase..
using other softwares maybe. like Iray in 3dsmax i know it uses gpu unless the vram needed exceeds the card capacity
