Next is an RTX On trailer of Call of Duty: Black Ops - Cold War. Unfortunately, no actual gameplay in this trailer.
Thirdly we have a "Welcome to London" RTX On trailer of Watch Dogs: Legion.
And a "New Worlds" reveal of Minecraft RTX.
NVIDIA also created "Marbles at Nigh", a new physics-based tech demo with ray tracing and DLSS support. The company explains "this playable demo has hundreds of dynamic ray-traced lights and over one hundred million polygons, running smoothly at 1440p on a single GeForce RTX 3090".
Do note that NVIDIA is no longer pushing RTX On vs RTX Off comparisons. RTX On is now the default.
