Input devices, text entry, rendering cost and audio — the things that behave differently once your Unreal app is streamed rather than running on the viewer's machine.
| Topic | The short version |
|---|---|
| Game controllers | Work with no setup, provided your project still has Unreal's default input mappings. |
| On-screen keyboard | Text entry on phones and tablets. Unreal 5.6 and above only. |
| NVIDIA DLSS | Renders at a lower resolution and upscales, buying frame rate on a fixed GPU budget. |
| Audio and microphone | Why sound starts muted, and why a mic permission can stop a stream from starting at all. |
| Mouse handling | The browser cursor is the fast one. This is the largest input decision you make. |
What works out of the box, and the one project change that breaks it.
