Here we're set to the most common resolution that mainstream gamers play at, according to the Steam Hardware Survey. Let's look at how performance scales for the entire field of cards, some of which were previously challenged at the higher settings.
At 1080p we see the GeForce RTX 2080 Ti still at the top of the boards of course, and you will notice that though FPS has still gone up, now DLSS cannot be enabled on both the RTX 2080 Ti and RTX 2080. RTX High on the 2080 Ti with DLSS off easily pulls over 60 FPS on average while the 1% lows once again are eclipsing 30 FPS and will make for a very playable experience. The Extreme quality level is brutal and as you can see the RTX 2080 pulls some decent performance but the 2070 finds itself in a tough spot on average, with a little over mid 40 FPS, while the 1% lows dip into mid 20's. This is without RTX features enabled at all, since at 1080p all cards do not allow DLSS to enable with RTX lighting disabled. Once again we'd offer that we understand why NVIDIA made the decision, but we would still like the ability to override that with a disclaimer about performance, so we could test this feature a bit more. At least if we had the capability to show this, maybe it would feel less like something not working and more like being cautioned on the feature because it does not provide a good experience.
