DLSS Feature Test Added to 3DMark

[Guest_Jim_*]

While a lot of focus for NVIDIA's Turing GPUs has been on the architecture's RT cores, enabling hardware accelerated ray tracing like NVIDIA's RTX technology, the RTX graphics cards are also capable of DLSS, Deep Learning Super Sample, another new NVIDIA technology. The idea behind DLSS is to train a neural network on higher quality versions of the scenes a consumer may encounter and then use the tensor cores in the GPU to apply what was learned to improve the image quality. Today a DLSS Feature Test has been added to 3DMark, so now all those with supporting GPUs can give it a try.

The way this test will work is to first run through the Port Royal benchmark with DLSS disabled, though an implementation of TAA is present, and to then run it again with DLSS enabled. (Port Royal is the ray tracing benchmark in 3DMark.) At the end the performance for both runs will be shown, but it is important to note that DLSS On does not render at the same resolution as DLSS Off. Besides being used to improve image quality, NVIDIA also states DLSS can be used to improve performance because it will render at a lower resolution and then use the neural network to upscale, and that is the case here. The 3DMark technical guide gives a table stating what the internal rendering resolution for given out resolutions:

DLSS Internal Resolution	DLSS Output Resolution
1440x810	1920x1080
1920x1080	2560x1440
2560x1440	3840x2160

If you do not already have a copy of 3DMark Advanced Edition, it is currently on sale at 85% off as part of the Steam Lunar Sale. As this test uses the Port Royal ray tracing benchmark, you will need to have access to it in order to run this test.

I reached out to ask about whether DLSS 2x (the mode where the internal resolution is not reduced) will be added and that is up to NVIDIA.
