AI Denoise does not work on my fairly new ASUS Zenbook Pro 17. The best results are images that are interfered by small colored squares randomly placed in the dng. (I enclose an example image.) But most of the time AI denoising stops processing, giving out an "unknown error", followed by the "GPU Error" ("The graphics processor has encountered an unrecoverable error. ...")
I tried to deactivate GPU support by default, but then AI denoise does not work at all.
When I activate GPU support by default, it crashes all time.
When I set it to Auto, it crashes most time, but sometimes it works - but with the small color patterns in the dng-results.
I also changed the settings of the AMD radeon to "Gaming performance" (= full power) after updating the driver.
Any ideas what else could solve the problem?
Or is the up-to-date AMD Radeon Graphics just to weak for the new denoise feature? That would be upsetting, because the Laptop is only 4 months old and i bought it especially for picture editing.

If that's integrated graphics (not a discrete GPU), it's most likely underpowered for this. Generally, integrated GPUs are simply not sufficient for running current versions of Lightroom/ACR/Photoshop.

Thank you. I am afraid you are right. I did some tests with a similar powered laptop, but with dedicated GPU, and it worked fine. So I hope ASUS will be obliging and let me swap the Zenbook I purchased just 4 months ago for a modell with Nvidia GeForce RTX 3050.

When you do, you may need to disable the integrated GPU to avoid conflicts. All laptops come with dual graphics these days, a potential problem for Lr/ACR/PS which all use the GPU for actual data processing (not just display).

Thank you. Miraculously it worked for a couple of pictures (but it took like 100 seconds for every picture, compared to the other system I tested (with Nvidia 3050 GPU), where it took 9 seconds per picture). After 5 pictures the error message was back, and since then Denoise AI was not able to finish one single task. Even if the laptop is freshly rebooted.

Correction: It took 30 seconds with the other system, not 9.

"AMD Ryzen 7 6800H with Radeon Graphics (3.2 GHz)"
"DirectX: AMD Radeon(TM) Graphics (31.0.12028.2)"
The installed graphics driver is out-of-date. Download the latest from here:
and see if the default installed settings work before tweaking them.

Thank you. I updated the driver, but it did not help. When I started "Denoise" it came to an error after 60 seconds and the AMD Radeon graphics was being disabled in the settings by Lightroom. Looks like I need a laptop with a dedicated GPU.
