Haven’t seen it mentioned anywhere, but the new dedicated Bluetooth module in the Steam Deck OLED is working a treat.
With my Steam Deck LCD I loved to connect my phone to the SD and listen to twitch while playing games. When I also connected with bluetooth headphones, I found sound got a bit garbled or completely dropped out within 30mins.
I can connect lots of Bluetooth devices to the SD OLED and maintain full wifi speeds with no issues! Latency appears improved as well.
