"What if you could say'Hey, add a flying unicorn here'? Or'Turn this into Star Wars,' and it's all Star Wars," says Leitersdorf. A major limitation right now is hardware. They relied on Nvidia cards for their current demo, but in the future, they plan to use Sohu, a new card that Etched has in development, which the firm claims will improve performance by a factor of 10. This gain would significantly cut down on the cost and energy needed to produce real-time interactive video. It would allow Decart and Etched to make a better version of their current demo, allowing the game to run longer, with fewer hallucinations, and at higher resolution.
