Analysis — Portal 2 on the Steam Machine
This kind of action game is GPU-bound on the Machine: the frame-rate follows resolution and post-processing. FSR is the main lever when frames get tight; effects and shadows go before textures.
328 ProtonDB reports rate it Platinum (runs perfectly out of the box), in line with Valve's Deck Verified rating.
Steam lists full controller support, so it plays from the sofa without a keyboard. It also has shared/split-screen co-op on Steam's list, which suits a living-room box with a second controller.
