They still haven't released the specs, but a fully functional build was leaked a few weeks ago. Did anyone try to play it on the deck? I know it's unlikely but I still hope that the game will be playable.
That build was a year old. It probably is missing a ton of optimizations that happen late in development so I would say it would still be nearly impossible to tell.
I think the date was not clear, there was some info that looked like it's a year old but also some seemed to be from last month. Given the campaign was fully playable I doubt it's actually a year old.
