OCC published Shadow of the Tomb Raider Performance Analysis
A quote from the article:
It has taken quite some time, but I have finally returned to Shadow of the Tomb Raider to look at graphics quality and performance. Though the long wait between when the game released and now may mean this is of less interest, it also worked in my favor as the game was not only updated to support ray traced shadows, but NVIDIA released drivers enabling Microsoft DXR support on non-RTX graphics cards, including the GTX 1070 and GTX 1080 I have for testing. DirectX Ray tracing (DXR) is a hardware-agnostic ray-tracing technology and so does not require the RT cores of NVIDIA RTX GPUs, but RTX is able to act as a layer above DXR, significantly accelerating it. The RTX GPUs also support NVIDIA's Deep Learning Super Sampling (DLSS) technology, and it too had support added to the game, so I took a look at its image quality impact.Shadow of the Tomb Raider Performance Analysis
