Rereading what I wrote – I think I misunderstood the complexity of reformatting for HiDPI screens. I didn’t consider all the interactive GUIs for individual plugins, particularly 3rd party ones. I would assume that in the future, the new Plugin Sentinel will also function to block plugins that are disrupting graphic performance (fps) or causing havoc in HiDPI modes.
That said, I believe HiDPI and interpolated elements can co-exist. An example would be Kontakt 5.6 within Vienna Ensemble Pro 6.
I know there are hard working people that have been determined to make Cubase Pro 9 a worthy upgrade. Some of the new features are genuinely compelling.
HiDPI is still a significant issue for me. It is understandable that audio developers have not focused on this because - it doesn’t affect the quality of the audio. With desktop monitors, I’m running 100% scaling at 1080p/1200p, so this isn’t an issue. My laptop screen is a different beast, as is any future upgrades to 4K monitors. HiDPI/Retina displays are one of the biggest changes in the Windows and Mac ecosystem. I believe the advantages outweigh the drawbacks, and it’s something developers should embrace as quickly as possible. In software environments where stability is paramount, I recognize this may not be easy.
I still don’t know when/if I’ll make the upgrade.
