Hello,
I am using lightroom classic for a while and I have issue with GPU. My GPU was Asus Radeon 6600X 8GB.
I always had to keep the GPU off in Lightroom otherwise it was going crazy like crash or work very slowly.
CPU was doing the job until the latest update for Lightroom which change the Denoise completely. (Ver14.4)
After the update each photo took around 12 minutes to denoise, so I had to buy another GPU which is Asus Prime Geforce 5070 12GB
After upgrade the GPU, denoising is very quick like 3sec for each photo but Exporting photos is very slow.
I tried all the GPU troubleshooting like delete the config file , reinstall Lightroom Classic completely, update windows and drivers,... but it didn't help.
When I turn off the GPU export is using CPU and it's a bit faster but still slow.
Also when I check the performance during the export it shows 2-3% GPU usage and 30-40% CPU
For example export 10 JPG each 20-30MB will take around 1.5 minutes.
Appriciate if someone can help me ti fix this.
I have attached the screenshot of preferences window.
