Lightoom GPU for building previews is a game changer

[hamsteve]

I run Lightroom Classic on two PCs. One is a Dell XPS desktop from 2019 (I7-9700 9th gen, 32GB RAM, nVidia 1660ti with 6GB NVME SSD boot drive and two SSD data drives). The other is a Dell XPS 15 laptop from 2021 (i7-11800H 11th generation, 16GB RAM, NVIDIA RTX 3050 with 4GB, NVME SSD drive).

I prefer to work with 1:1 previews, and usually generate those previews at import time. The last time I tested the performance of these machines generating previews, I was getting about 4.5 to 5.5 seconds per preview on each of them (for 32Mpx CRAW files from an R7). The laptop was clearly constrained by its smaller amount of memory.

Today I upgraded both machines to Lightroom Classic 14.5 and tested again. With the new GPU acceleration support for previews turned off, the desktop performance was 2.3 seconds per preview. With the GPU acceleration turn on, it improved to 1.6 seconds per preview. I repeated this test after a reboot, and got 0.97 seconds per preview.

The laptop also showed improvement: 3.7 seconds per preview with acceleration off, 1.2 seconds per preview with acceleration on.

So even without the GPU acceleration, Adobe has significantly improved performance for 1:1 preview. And the GPU acceleration makes it even better. This is going to streamline my Lightroom work.

I just built a new system with an AMD RYZEN 7 9800X3D and I had to upgrade my graphic card since my Asus 3060 ti wouldn't work on my new build with an Asus motherboard without having to start the computer several time...

I upgraded to the Asus 5060 8gb

I just ran a test and to generate 1:1 from my Nikon D850 (7360x4912) . For 10 images it took 8.5 seconds.
