Question

Lightroom does not use the GPU GTX 3090.

I had a GTX 1080 TI card, I bought a new, efficient RTX 3090, the card works great in Benchmarks. 
I installed new drivers.
Lightroom Classic 13.5. 
Driver 

Problem: the program does not use the card. It makes no difference whether:
1. Auto is enabled
2. Manual
3. Card support is disabled.

I checked the card on 2 drivers:
1. 560.81-desktop-win10-win11-64bit-international-nsd-dch-whql
2. 560.94-desktop-win10-win11-64bit-international-dch-whql
The effect is the same.

How can I solve the problem with exporting photos.

    By the way, from:

     

    in your Device manager, is your integrated video controller enabled, dome have an issue with that (in my case I have that disabled in the BIOS, an option some may not want to contemplate)  Just disabling it in the Device Manage can help.

    You may want to contact Adobe. Typically via a CHAT, and when doing so, be assertive to request an actual Adobe Tech to join in or contact you. Include the link to this discussion in the chat.

     

    To do this, bring up fairly much any Adobe Web Page, And look for the Contact buttons. Looks like:

     for example at:

    For me it looks like this. I absolutely have to replace the processor with a newer one.

    If you had a 1080 and upgraded only your GPU, i think you have an ancient CPU. And this is your problem. You are bottlenecking your GPU. It will not go faster...

    It certainly is.

I was convinced that LRC uses 100% of the GPU and relieves the CPU.

I have to change the CPU to a faster one.

Best regards

    Hi GoldingD,
I've implemented your LRC optimization tips 🙂 from the link you provided.

I have a request, can you check or make a print screen while exporting photos to JPG.

I'm curious to what percentage the card is charged.

    Thank you for the tests, what is your CPU and GPU coverage if you export e.g. 100 photos?

Best regards, Marcin

    Thanks GoldingD for your support.

I finally updated to Windows 11 and it's ok.

I'm disappointed that LR doesn't use 100% of the card's performance, which is a shame.

Best regards Marcin

    I do not see this on my rig, but mine has a RTX 3070.

    Have you ever considered:

    I found a DXdiag file showing how the DX 12_2 library should look like. I suppose that's the cause.

Updates don't help. I removed the drivers with a special program and installed the latest ones. Nothing helps.

    From what I've learned, GPU support in Lightroom is for cards with DX 12.2.

    RTX 3090 has 12.2 support.

    I don't know why Windows 10 sees 12.1?

    I cleared Windows 10 of previous drivers. 
    I reinstalled the latest ones.
Unfortunately, it didn't help.

For me, exporting 200 RAW to JPG takes 10 times longer.

The screenshots show that the card is not used.
