For me, it highly depends. Turn-based strategy games, I can easily play at a much lower framerate (30 is fine tbh though I always appreciate more). FPS-style games? 60 is a bare minimum, but 100+ is what I would consider to be enjoyable.
For others who also don’t know what this is:
darktable is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.
It was mentioned in the notes for 1.84.0 that they began migrating to it. They might be doing it without an edition change if it’s backwards compatible (or if the incompatibilities are considered bugs).
