Living the dream
A big part of the Deck outselling the competition is price. An Xbox handheld could be sold at a loss (like the deck) with the plan of making the money back on Microsoft store/Xbox store sales.
Gaming laptops are both too big to be portable, and yet subpar for a desktop experience. I feel like they're an inconvenient compromise between something focused on being a portable gaming experience and a desktop computer, and they fail to meet either need well.
My experience with them is they're too large to be portable in any sort of convenient way, have terrible battery life, struggle to compete with desktops for performance (without spending a huge amount on the laptop), frequently have overheating issues (especially as they age), and lack the upgrade freedom of a desktop requiring you to buy a brand new laptop every few years.
My personal experience is based on an $1850 Asus gaming laptop I had 10 years ago though, so maybe things have changed since then or other brands are better.
To be fair, gaming laptops kinda suck (at least they did when I owned one). I would probably recommend a steam deck + a desktop over a gaming laptop.
Must be, there were at least 3 new handheld PCs announced last week.
I would expect it to be a loss leader. The cheap price combined with brand recognition, advertising, and a streamlined experience could make it a successful product I think.
If it's Xbox branded they could probably get away with it.
This actually isn't about Genshin, but Wuthering Waves instead.
I don't think you have to be this secretive about it
There are similar workarounds for Genshin (no longer needed last I heard) and HSR, but all they request is that you don't link any of the workarounds publicly.
Here a link to bypass the paywall:
They use the xbox brand for microsoft store pc games too, and it's probably those + gamepass that it would run. Those should let you lower the graphics.
Also if the device is successful, it might actually get more devs to release their games on the Microsoft store instead of just on Steam, which would be a win-win for Microsoft.
