I can confirm that with the new nvidia drivers davinci does see the gtx580. What you won’t see is a boot screen on it. You need a seperate gpu to run your gui.
The folder structure is very particular. Try moving the sub folders so that it’s just the mxfs inside the f65 folder. That’s just a wild guess, don’t know if it will do anything, but it’s easy enough to try right?
I’ve render 4k at less than rt without issue. Not aware of a memory issue re: 4k images. But it makes sense. I think safe to say with VRAM more is better.
The AE plugin architecture is showing it’s age. And I’m unsure how the licensing works. If Adobe needs to approve, I doubt they would considering their purchase of Speedgrade.
I think as users and from BMDs perspective it would be good to adopt the OpenFX plugin architecture.
