Pokémon X gets a positive verdict in a short test on Lite’s GammaOS preview, with shader-compilation stutter and occasional graphical issues reported. The Azahar Nano menu shows 2× with dynamic resolution On, so it was not a fixed 2× throughout.

Fire Emblem Awakening’s opening and tutorial battle get a positive verdict on Lite’s GammaOS preview, with some dips. The reviewer had already run the game once to compile shaders, so a first launch may run worse.
