It is still in Beta and apparently with some issues as expected. I also use it but, good and very powerful( compositing- Fusion -, color correction, sound) but the editing experience is overall inferior to Vegas.
Edit: interesting that we have been talking about Lighwave etc, older applications and one of compositing veterans Digital Fusion ends up inside Resolve. That must have been a great piece of engineering by Blackmagic integrating Fusion in Resolve.
Edit2: one of the things i also like is that even in free version when i encode to mp4 it is super fast and get my Nvidia+CPU to 100%.
