Has anyone come up with a way to run PL on Linux with decent performance?

Reports of Windows 11 and Mac problems are to be taken seriously. I, too, am aghast at the constant reports I see about Windows features breaking with updates, for example. However, not everyone experiences the problems. I haven’t had any issues at all (affecting PhotoLab or day-to-day use) with Win 11 on three different computers. And I generally keep everything up-to-date. Similarly, Joanna has said of Mac, “it just works” while others might not agree…

Unfortunately, that recent topic produced almost no discussion about running DxO software from Linux. Instead, posts focused on getting along with Win and Mac.

This next topic is more relevant to your inquiry about PhotoLab-on-Linux performance:

I hope you get a good response here!
