On first blush, the biggest difference in the new Fire TV UI is that everything is rounder. Shows, movies and apps have rounded corners, and Amazon's changed the spacing in the interface to give everything more room to breathe. Tweaks to typography and color gradients also give the UI a more modern feel, and Amazon says it's rebuilt the code of the Fire TV software to make everything faster, too, in some cases demonstrating "up to 20-30 percent gains in speed."
Baldur's Gate 3 is apparently even better to play on the go now, as Larian Studios has released a new native version of the RPG for Steam Deck as part of a hotfix. The developer states that the game has "a more stable frame rate, lower loading times, and smoother gameplay" on the PC handheld. Larian detailed what's included with hotfix 34 on Steam, with the spotlight on the Steam Deck-native build.
