This will come into play for the quality comparison. As you can see, the performance of 4K at 78% resolution, which equates to a resolution of about 2995 x 1685, is roughly the same as 4K DLSS. Crucially, we've also added in the performance with the game set to 4K but with a 78% render scale.
Testing at 4K with the RTX 2080 TiĪbove you have the performance at native 4K, then performance at 4K with DLSS enabled, and native 1440p. We tested Battlefield V with a Core i9-9900K rig, and for this initial batch of 4K testing we used a GeForce RTX 2080 Ti with all settings set to Ultra. Many popular configurations, especially those that deliver high-framerate gameplay like the RTX 2080 Ti at 1440p, can't benefit from DLSS.īefore we jump into the image quality comparisons, we wanted to go over the performance results first. This definitely prevents DLSS from being that one-click performance improving feature Nvidia advertised it as. The video version of this feature showcases scene differences in motion and greater detail in some instances: So Nvidia has made the choice to block users from activating DLSS in situations where the performance uplift is negligible, or in some cases even worse than just native rendering. As your performance level increases, DLSS begins to occupy a proportionally higher percentage of the rendering time, up to a point where for fast GPUs, it takes longer to process DLSS than it does for the native frame. And there are similar limitations with Metro Exodus.Īccording to Nvidia, the reason for this restriction is that activating the neural network for DLSS takes a fixed amount of time for each frame. However if you're a 1440p gamer, the option is only available for the RTX 2080 and below. If you're playing at 4K, all RTX cards can access DLSS. So if you simply wanted to use DLSS to boost performance ray tracing aside, that is not possible.īut it's locked down further, on a GPU by GPU basis.
That's already disappointing, because we feel most gamers should play with ray tracing switched off.
In the case of Battlefield V, you must have DXR reflections enabled to enable DLSS, so there is no option to use DLSS without ray tracing. In all DLSS games released so far, the feature is locked down, preventing you from simply enabling it with any combination of settings or resolutions. But both Battlefield V and Metro Exodus have good anti-aliasing, which provides an excellent comparison between DLSS and a high quality native image. But because that game has a terrible anti-aliasing implementation, we decided it was not a good test bed and is not reflective of most other decent games. However, we still discovered back then that DLSS performed roughly the same as reducing the image from 4K to 1800p, while providing roughly the same image quality as 1800p.ĭLSS has also been available in a real game for a little while, Final Fantasy XV. The demos weren't particularly great as they were canned benchmarks, which we felt would give Nvidia's DLSS neural network an unrealistic advantage at optimizing the image quality, compared to a dynamic game environment. When we looked at DLSS back in September, there were only two demos Nvidia had for the launch of their RTX GPUs. For now we're sticking with Battlefield V in this investigation because according both Nvidia and developer 4A Games have said the DLSS implementation in Metro Exodus still needs some polish.
1080P BATTLEFIELD V FULL
We previewed it months ago, but until support arrives on working titles, there was just so much we could learn about it besides looking at demos and what Nvidia claims will be possible with it.ĭLSS finally made its way to both Battlefield V and Metro Exodus this month, and as is the usual case for us, we'll be going through a full visual and performance breakdown in this article. Nvidia's deep learning super sampling, or DLSS, is one of the highly anticipated features present on RTX graphics cards.
