If you are on a 5GHz network and your Xbox One is connected to an ethernet port, you're going to enjoy OneCast a lot more than if you have to rely on WiFi. Lastly, OneCast can run into some lag, but this depends greatly on your network setup.
#Onecast no longer allows streaming across the internet windows
This limitation is shared with Microsoft's version of streaming from the Xbox One to Windows 10, so it's completely understandable that OneCast has the same restriction.

The developers recommend your Xbox One be hardwired to your network to achieve the best performance, which isn't an option for everyone such as students who share a router. OneCast also requires your iPad and Xbox One to be on the same network. Thankfully, OneCast supports MFi controllers and has good on-screen controls, so you have options. Apple sells devices that let you add physical controls to your 12.9 inch iPad Pro, 10.5 inch iPad Pro, or your iPad Mini, but they aren't cheap. The iPad's lack of a kickstand or physical controls limits the versatility of OneCast. This might seem like an unfair comparison because the Switch is a dedicated gaming console, but OneCast's developers are the ones that bring it up in the app's store listing which states, "Take the awesome power of your Microsoft Xbox One console, and give it the portability and convenience of the Nintendo Switch." The first of which isn't the developer's fault but still limits OneCast the iPad isn't as ergonomic for gaming as the Nintendo Switch. While I am a big fan of OneCast, it does have some issues.
