Yeah there’s a good chance you’re right. Maybe something to do with memory management as well.
Long term I’ll probably end up switching back to Darktable. I used it before and honestly it is quite good, but I currently have a free license for CC from my university and the AI denoise features in LR are pretty nice compared to the classical profiled denoise from Darktable. It does also help that the drivers for my SD card reader are less finicky on Windows so it’s easier for me to quickly copy over images from my camera on there instead of Linux. Hopefully that also gets better over time!
I work in CV and a lot of labs I’ve worked with use consumer cards for workstations. If you don’t need the full 40+GB of VRAM you save a ton of money compared to the datacenter or workstation cards. A 4090 is approximately $1600 compared to $5000+ for an equivalently performing L40 (though with half the VRAM, obviously). The x090 series cards may be overpriced for gaming but they’re actually excellent in terms of bang per buck in comparison to the alternatives for DL tasks.
AI has certainly produced revenue streams. Don’t forget AI is not just generative AI. The computer vision in high end digital cameras is all deep learning based and gets people to buy the latest cameras, for an example.
