I can't find a way to switch to scrubby zoom in InDesign 16.1. I see a lot of guides saying something about "Preferences - GPU Performance", but this menu is simply not available to me.
I'm using the following (if that ends up being relevant)
- Nvidia GeForce RTX 2070 SUPER
- 2x Dell 24'' UltraSharp Monitors.
As Bob rightly mentioned, as of now GPU performance is available for macOS only, that too on a very few devices. Here is the list of supported devices: https://helpx.adobe.com/in/indesign/using/gpu_performance.html
In case you are working on Windows OS, please upvote this feature request here ( https://indesign.uservoice.com/forums/601021-adobe-indesign-feature-requests/suggestions/31872184-gp... ) and stay tuned for updates.
We need this feature in next release, dear adobe developers please add this and make this software more user friendly.
