So wait, the GTC keynote which was scheduled weeks/months ago, happens to follow news that Epic dropped with absolutely no warning, and apparently that counts as stealing thunder. Is that really what you are saying?
Nvidia probably collaborated on the Epic demo but also they are aimed at two entirely different sets of customers. Nvidia's news cycle is data center updates in May, consumers/gamer updates in September.
Epic demo was running on PS5 so no NVIDIA involvement there.
Oh yes, I forgot they've entirely lost this console generation.
Well not entirely (and depending on what you count as this console generation): the Nintendo Switch is based on an NVidia SOC. Although that's probably not the biggest money maker.
And the entire HPC exa-flop super computers as well.
