I'm worried because since last night when I open the Octane preview and I work with it the system slows down a lot. Since yesterday I can not have the preview open and running when Im modelling or moving things around, I can barely change in between applications because it lags a lot and feels like it's going to freeze.
Im working with a mac pro mid 2010, 24gb ram and a gtx 680, i know its not much graphic power but till yesterday it was enough to work smoothly in cinema 4d and have the preview open.
It's set to low priority and direct lighting.... I really don't know what it could be. Could it be that the graphic card is damaged?

Thanks!
