Denoise issues (RESOVLED...LIKE IN FIXED)

PostSat May 30, 2015 10:27 pm

Anybody else has this problem using spatial denoise with chroma? If I unlink them and only change the chroma I get that RGB images. If I combine both luma and chroma I get grey spots all over the image. (Scroll to see the entire image)

I never had this problem before. I wonder if it's the latest nVidia driver update that created that problem or if it's Resolve 11. I never had problems with version 10.

I have two cards, a 660 and a 980.

And please, don't just tell me that it works for you because this doesn't help at all. :-)

EDIT: CUDA V7 was the problem. Switched back to 6 and everything OK now.

Use the older cuda driver 6xxx.45 or something and it works great. The newer cuda 7xxx messed it all up for me.

I thought people were having other NR problems with the 980 and the older driver, that's why I didn't switch back?

I had the same issue. I have a titan X and the problem stems from the maxwell architecture on the cards.
that issue has been documented here: viewtopic.php?f=21&t=34037

What version of davinci are you running. As of version 11.3.1 Maxwell architecture support has been added. Link for proof.

I recommend updating to the latest version of davinci and latest CUDA drivers and check if you have still have issues.

I'm running the latest version of Resolve but the problem was CUDA 7. I switched back to 6 and it's OK now.
