Hardware Unboxed picked up on this when Digital Foundry made a review of the 3080 before the official NDA lift, Doom Eternal was also featured in Nvidia's performance slides.
It did lead to people thinking the 3080 was going to be twice as fast as the 2080, Jensen made similar claims in his kitchen on that day. A lot of people on the internet used it as a performance measure comparatively to the 2080 and 2080TI.
Long story short Hardware Unboxed reiterated his findings in the RTX 3080 review.
That is with the settings Digital Foundry used Doom Eternal would use 9GB of VRam, the RTX 2080 only has 8GB, this would cause the 2080 to choke on that lack of VRam and the performance is a lot less compared with the 3080 than it is with reduced Texture Quality setting that use only 7GB of VRam
4K Ultra Nightmare (9GB)
2080 88 FPS (100%)
2080TI 140 FPS (159%)
3080 189 (215%)
4K Ultra Nightmare, Ultra Textures (7GB)
2080 111 FPS (100%)
2080TI 140 FPS (126%)
3080 189 (170%)
To be clear, with reduced texture quality settings the 2080TI and 3080 are identical in performance, the only change is the 2080, the 11GB 2080TI was 59% faster and that changed to 26%, the 10GB 3080 was 115% faster, that changed to 70% faster.
