odederell Posted July 6, 2014 Share Posted July 6, 2014 Hello all, What would be the best setup for rendering with Iray? a) One Geforce Gtx 780 Ti GPU b) two Geforce Gtx 770 GPU's If option b is the best, Is it important to get the 4Gb addition of the 770 card or should the combined memory of the two cards be enough? Thanks for any reply, Cheers! Oded Link to comment Share on other sites More sharing options...
erkutacar Posted January 28, 2015 Share Posted January 28, 2015 iray doesnt do combined memory, coz its not serial, its parallel processing. if it cant load the scene into the memory of the 1st card, skips to the next card. so if u wanna use more than 1 card, u need the most possible ram for ur gpu. if u use 1 4gb card and ur scene is more than 4gb, (keep in mind windows will be using about 700mb of ur gpu ram) then iray only used ur cpu. 2 cards is always better than 1 card coz more cores!

ziosavo78 Posted December 7, 2015 Share Posted December 7, 2015 Hi, for exterior if you use to much tree and grass you need to buy gtx 980ti or titan x. If your target is interior designer you can buy gtx 980 or 970 (4gb are Right for an interior of mid complexity at 5000x3750) Inviato dal mio Xiaomi redmi 2 pro Link to comment Share on other sites More sharing options...
