well they sure can do that. but it would be more important to try to work with developers to make sure their first gen Steam Deck will get actually supported.
they should try to convince developers to directly target their system with their lowest settings in order to make it actually future proof. because it won't be at all if developers don't do that.
like I said, I wonder how even a current game like The Medium run on it, because that is already on the edge of acceptable on Series S! and it will only get worse.
they can update, but if they do without making sure their original version is well supported they will essentially leave their day 1 customers in the dust
U use console logic. I use PC logic.
This is the difference:
PC logic :
Steam deck will have all the support day one because its a PC. Nobody has to beg cdpr to optimize there game for the deck because u can either do it yourself or it already works for you or somebody posted the settings for optimal gameplay 10 seconds after release.
Console logic :
We need lots of support from devs and they need to optimize for it, because otherwise we won't see games.
PC logic:
U buy a piece of hardware right now, and if tomorrow a new one comes out so be it. U either wait for that or u are happy with what u got and buy into it and upgrade later on if you need more. ( options ), or skip the generation and move to the next after that if its to quick.
I got a 9900k, there are now 3-4 gens of intel cpu's above it? do i care no. I paid 500 for the cpu, year later new cpu launches. i don't care. i will upgrade when my 9900k isn't performing anymore probably around 2024-5
Console logic:
It needs to be supported by every new title in the next 7 years or else its not worth it. If a new device comes out in a year people will feel bad about buying it, because they demand 7 year support.
Will there be games that don't run on the steam deck?
yes.
Will those games come sooner or later or are they already here?
who knows. I play anno 1800, let me load in my map see if it can hold more then 2 fps. as my 9900k hits 15 fps at times. It's all what u want and what u do.
Hell witcher 3, that runs on some people's 1080ti's at 150+ fps. at mine it drops sometimes under the 60 at 1080p why? mods.
The thing is u have full control over stuff, pc gamers will make profiles will make mods / updates to make the games run optimal for the deck anyway in seconds.
Want to see how far player optimization can go? here you go. lego flight simulator.
Here from 2 fps
From 2 fps to 48 fps.
The biggest issue PC has is support for architectures. if your architecture of your GPU is to old it can result in you not being able to lpay something because its only made for newer architectures. With the architectures used on the deck that's a non issue.
For example i got a 1080ti, yet that 1080ti is beyond faster then a 2060. still a 2060 has a newer arechitecture and can play metro enhanced edition. My 1080ti can't. Do i care? no ( never tried it however so yea there is that, but i assume its a no go ).
