Finally got around to giving Chiaki a try and I was surprised by how well it works. It was occasionally choppy with both devices on Wi-Fi, but once I put the PS5 on wired/ethernet it worked great. In an hour of gameplay it only broke up once, turning green and blocky for a couple seconds. Other than that it with smooth, responsive, and had great image quality. I followed
Deck Wizard's tutorial and settings. It's cool that it can wake and sleep your PS5, and run it without the TV being powered on. It's not really a downside, or unexpected, but it does run in 16:9, so it's letterboxed on the Deck's 16:10 screen. Shit looks really good on Deck and has decent input latency due to the 60fps mode available in many games.
