Actually a lot of games probably DO support 16:10, since apple has always pushed the format and a LOT of laptops are folling suit in recent years. its not like its hard to make a setting for 16:10....
as for the performace, remember that the switch's hardware, the launch model X1 chip, has raw performace capable of near 1.9GHz on the CPU and 1GHz on the GPU when the switch, due to wanting to run consistantly and without overheating, runs at a lower rate even while docked(1Ghz and 750Mhz), and around 60% of that on the GPU undocked, meaning that in portable mode the switch is only using around half the performace of the entire chip.
now while the steam dock might be more open, clock speeds might be BIOS limited.
Not that I disagree with the other guys. But this is more what I'm thinking. Just seems like a waste of battery for improvements that would go unnoticed. Or have this big thing overheating on your hands with a loud fan on.
I'm thinking a portable mode is gona come by default. But if your willing it could still allow you to change settings.
It takes genuine talent to see greatness in yourself despite your absence of genuine talent.
