A few outlets managed to run a demo of the Shadow of the Tomb Raider on the new NVIDIA GeForce RTX 2080 Ti and the initial impressions seem to be a bit dampening with ray tracing turned on. The game was shown to hover in the 30 fps range in 1080p and struggled to reach 60 fps. A demo without ray tracing was not shown but it should understandably result in a huge performance difference.
