Todd Howard asked on-air why Bethesda didn't optimise Starfield for PC: 'We did [...] you may need to upgrade your PC'

It's funny, Steam Deck is so much weaker than the typical gaming PC and will definitely not outperform an ~RX 6700XT at the same quality level but Steam Deck resolution vs at 1440p. Worse, Steam Deck shares 16 GB of RAM between CPU and GPU, so this guy is gonna have an even smaller list of games they can play on a docked Steam Deck vs a PC.

Also, Steam Deck can't be (read: processing power) upgraded, and doesn't have 3D-VCache, that's not good for CPU bound games. And then you might also be defaulting to Steam OS, which doesn't have full compatibility with Windows games, and have a complicated compatability file structure, which could complicate modding and 3rd party utilities.

So yeah, Steam Deck as a complete desktop replacement has more issues than you might expect. And the worst part is, absent docking portable HDDs, everything is an SSD, so welcome to the SSD $/GB world. TF cards have even worse $/GB.
