"improving iteration time natively on-device is one of our top priorities this year (once we get the hardware out the door!). I don't have anything i can talk about right at this moment, but we are heavily focused on making this more palatable during development. There's a lot of tips and tricks we'd like to share once things go public, and the forums are a great resource for things like working around long shader variant compiles. We're working on it!"

is there any news on that?
