I would like to know if it's possible, from now, to have normal mapping in Cycles ? I saw a node called "normal" but the result is not as wanted
.An other question, Do you planed to include shared memory between GPU and the system RAM ? I think is one of the thing very frustating when you have a geforce 670 4 Giga of ram and 16 Giga of system ram, not the possibility to give the system ressources to the gpu, cause gpu is really fast
. Or an hybrid mode, that use gpu and cpu together (like in Indigo render, but much faster like current cycle GPU 
)But Cycles is a really really good engine, really powerfull.
Thanks in advanced,
Matt
ps : the build is the 2.64 test 2 x64.
