Hi

I want to by second Graphics card for low price (i target sometching gtx 650 ti) for view port not for render
I have one question about VRAM. If i buy some older slower card with 3gb and i enabled both to renderer is VRAM from botch card are added and my GTX 780 ti could use 3gb+3gb from second card?

Scene shouild fit into vram of every card so You're always limited by smallest card if You render on multiple GPUs - in this case You will not see 3+3, but only 3 - that's how it goes =)

So if i have 1gb on one card and 3gb on anotcher the overall scene may have only 1Gb tor txt etc.

But if i bay slower (small cuda naumber) but witch 6gb and second card has 3gb then cuda cores are added and my scene could have 6gb??

if You'd run only screen from that smaller card & render only on the 6gb - then You have 6 Gb to fit models, textures, etc. But if You use both cards (3gb & 6gb) to render - Octane will only see 3gb (limmited by smallest card used for rendering =) got it?

ok, now everyting is clear
thanks for quick response
