When turn off the SLI technology, the rhino played normally.
what is the problem between the newest Rhino and Nvidia SLI-Titan rtx??

sombody help me.

maybe If i knew this problem in advance, I buy Quadro RTX 800…T_T

SLI only helps in game-type situations, Rhino (or any other “content creation” app) doesn’t do anything with it. I guess NVLink can speed up communciation needed for CUDA rendering, but that’s again nothing to do with Rhino’s normal viewports. What are you expecting it to do faster? The last time I enabled SLI it didn’t do anything in Rhino but it still worked fairly normally. Is Rhino up to date? Are the drivers up to date? Is the Bridge connected?
