Question

Using Unity for Horizon Mobile instead of Desktop Editor

I have a RTX4090 Windows 11 PC with plenty of RAM and a high frame rate monitor. Horizon Desktop Editor's UI is extremely laggy to the point where I am literally getting migraines. 

Is this possible to simply use Unity instead?

I would call the Desktop Editor buggy rather than laggy. I do find it easier to use even after using Unity for several years. I just wish that they would fix the bugs. I especially hate the one that sets one scale for a mesh to zero every time I touch it.

Unity has a lot of community customizations and also allows you to fully customize the editor so that you can have shortcuts, etc - great for both being efficient (think Autodesk Certified Professional level and higher) and rapid prototyping. Desktop Editor is completely lacking in terms of professional usability. 

Also we actually run Unity headless on the command line and have our own internal frameworks and breakthru HCI frontend

Not for me. I have a Titan card with 128 Gb of RAM. Maybe it is a memory issue?

wow... 128gb ram required to run Horizon Creator Desktop without lag is a bit much - even Unreal maxed out doesn't require that

128GB of ram is not a requirement for using the Desktop Editor. Desktop Editor currently has the same PC requirements as Quest Link. 

If you’re seeing issues with the UI lagging, can you make a bug report in the Desktop Editor? A video would also be helpful. We don’t expect that the UI should lag and especially not enough to cause headaches.

Desktop Editor (+ a 3rd party IDE) or in-headset tooling is the only way to build for Horizon Worlds right now.
