Screen occasionally flickers when using Denoise

[Carlos De Smet]

Als ik denoise AI gebruik in de laatste versie van LR Classic, dan valt mijn scherm af en toe uit of flikkert het.

[F. McLion]

Aaaand .. your question is?

You need to supply much more information regarding your system and the photo as CPU, GPU, screen size/resolution, image source and resolution ...

[Ian Lyons]

Please provide your 'System Info'. This can be obtained from the Help > System Info menu.

[AxelMatt]

It seems your GPU isn't suitable with the Denoise function. It's very resource intensive.

Please provide also a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item.

There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

Then we can say more.

"DirectX: NVIDIA GeForce GTX 1060 3GB (31.0.15.2802)"

You're running a graphics driver that's three months old. You may be able to get better performance by updating to the most recent Studio driver:

https://www.nvidia.com/download/driverResults.aspx/204243/en-us/

[AxelMatt]

The problem with the flickering monitor you see is that your graphic card isn't realsuitable to use Denoise.

Your card does have only 3 GB of memory. that's not enough.

Take a look here: Denoise Demystified | Adobe Blog

There you'll find the following:

...

Denoise is by far the most advanced of the three Enhance features and makes very intensive use of the GPU. For best performance, use a GPU with a large amount of memory, ideally at least 8 GB. On macOS, prefer an Apple silicon machine with lots of memory. On Windows, use GPUs with ML acceleration hardware, such as NVIDIA RTX with TensorCores. A faster GPU means faster results. 

...

You have to live with it or you have to change your graphic card to a stronger one.

I've seen the same flickering on my system. My card is nearly the same. I've been using the GTX 1050Ti with 4GB.

[Keith Reeder]

My GPU (which, to be fair, isn't exactly state-of-the-art) has 8gb, and I still get the flickering.

Doesn't bother me, but it's certainly there.

[GoldingD]

Consider:

https://youtu.be/tELpPlkXlVE

[Carlos De Smet]

I installed the last driver and made the adjustments as done in https://www.youtube.com/watch?v=tELpPlkXlVE

The problem remains

Too little memory on my video card or bug in LR Classic??????????

[Keith Reeder]

Unless the new driver has miraculously increased the card's memory from 3gb to 8gb, I think the answer is pretty clear.

[Carlos De Smet]

Ik heb het gebruik van GPU (videokaart) uitgeschakeld en het probleem is opgelost wat betreft de flikkering. Denoise werkt nu trager door enkel gebruik te maken van de 32GB RAM.
Ik zal eerdaags een grotere videokaart kopen en hoop dan tot een betere oplossing te komen.
Ik infrormeer u verder

I have disabled GPU (video card) and the flicker issue has been resolved. Denoise now works slower by using only the 32GB RAM.
I will soon buy a larger video card and hope to find a better solution.
I'll inform you further

[A.5F90]

I have the same issue when i use denoise or Create Panormamas  "Screen is fickering during process" 

My GpU card has 12gig rtx3060  my memory  is 64 gig  and i have CPU i9 14900K

I have to make a correction to my report  ( i can not edit my original post )

It is only the picture with in Lightroom that flickers not the full screen 

[F. McLion]

You are using an outdated driver for your Nvidia card (472.12). Please download and install the latest driver available from Nvidia (551.86).

https://www.nvidia.com/download/driverResults.aspx/223498/en-us/

[D Fosse]

I know this is an old thread, but since it was resurrected: I think a little occasional flickering during Denoise is normal and nothing to be concerned about. I get this on two machines, one with a 12 GB RTX 3060, and one with a 16 GB RTX 4060 Ti.

Denoise is as fast as it's supposed to be, and works perfectly on both.
