Optimisation fails: Monster Hunter Wilds is almost impossible to play on Steam Deck and other handheld consoles

Monster Hunter Wilds will be released on the 28th of February, which promises to be a new gem in Capcom's portfolio. But the information published by PCGamer portal can spoil the mood of those who like to play games on handheld consoles.
Here's What We Know
PCGamer journalist tried Monster Hunter Wilds on different portable PCs and first of all on Steam Deck, which dominates this segment. Unfortunately, he stated that it is almost impossible to play Wilds on such devices.
Formally, the game launches and provides the user with a fairly wide choice of settings, but no matter how the player does not change the graphics quality and other parameters, the action works poorly, and its performance even in the Hunters' Camp, where there is no dynamic action and not many characters, does not reach 25 FPS. During battles the situation is even worse, even AMD FSR anti-aliasing technology doesn't help.
Things are somewhat better on the ASUS ROG Ally, which provides a stable 30 FPS, but this requires the right configuration of low and medium settings.
Perhaps Capcom will improve Monster Hunter Wilds' optimisation on handheld consoles after release, but right now the situation is sad.
