It is, but not everybody has an nVidia GPU. I have and use it, but there are still problems, such as the previously mentioned VST scaling.
I use 2 monitors, a 4K as my main and a full HD as a secondary. If a plugin opens on the HD display, it always opens with half the GUI missing. I have to drag it back to the 4K display and close it, then reopen it on the 4K then drag it back to the HD where it displays correctly. As we say here in the UK, it’s a right faff.
