Even if your network is relatively fast, streaming performance may be choppy or entirely unusable. It's also worth noting that streaming technology is still pretty new, and it won't be perfect. Graphics and streaming were comparable in my tests, but it'll depend heavily on your device and network quality. If you run into any issues or missing features, give Moonlight or AMD Link a try. In my testing, it was a smooth experience for most games, though a few had quirks (like a black screen). I recommend starting off with Steam Link. The Razer Kishi was also developed in partnership with Gamevice. Check the Gamevice website for a controller that matches your device. It attaches directly to your device and turns it into a Nintendo Switch-like gaming console. Personally, I highly recommend a Gamevice (Opens in a new window) controller. Android users can even use a wired controller, like an old Xbox 360 model, by connecting it into a USB OTG cable (either Micro USB (Opens in a new window) or USB-C (Opens in a new window)) and plugging that into your device. Otherwise, you can use an Apple-approved made-for-iPhone MFi controller (Opens in a new window) for iPhone or iPad. Just pair it with your iPhone or Android device through the Bluetooth settings like any other wireless accessory. Any Bluetooth gamer controller should work fine.
