Quote:If you’re having trouble keeping all of this straight, allow us to summarize. The 1080 Ti’s performance scores imply that very little AA is in-use at 4K, while the RTX family’s performance jump from Graph #1 to Graph #2 implies that a heavy AA solution has just been disabled and replaced by a much more efficient one. With a heavy AA solution engaged, the 1080 Ti’s average level of performance should be much lower (check our own review results above in Rise of the Tomb Raider and Metro Last Light Redux for examples of how much performance you lose when enabling SSAA).
One more thing. Nvidia’s 4K@60 line is 131 pixels tall, which means each pixel is “worth” approximately 0.46fps. The height gap between the RTX 2080 and the GTX 1080 Ti, measured top-left corner to top-left corner, is 20 pixels. If we assume that Nvidia’s graph is accurate, this implies the RTX 2080 will outperform the GTX 1080 Ti by ~9 percent at the same price (if $700 cards are even in stock for launch). And this, in turn, may explain why Nvidia is putting so much emphasis on DLSS and ray tracing in the first place — because introducing a 9 percent performance improvement at the same price isn’t anything that’s going to get anyone excited.
