The continuation of the reboot of Tomb Raider series “Rise of the Tomb Raider” has been updated with the promised features – benchmark tool, new technology of NVIDIA ambient occlusion (exclusively for Maxwell GPUs) and support for the latest iteration of Microsoft DirectX 12 API.

Rise of the Tomb Raider – Patch # 5 implements DirectX 12 and NVIDIA VXAO 

In the images below, we can see a significant improvement playing with a Core i7 2600k and GTX 970. Around 46FPS while playing with DirectX 11, and sold 60FPS with DirectX 12.

The above advantage (comparative screenshots) we feel is the most important one for Rise of the Tomb Raider, but there are many more advantages that make us excited about DirectX 12. Another big feature, which we are also using on Xbox One, is asynchronous compute. This allows us to re-use GPU power that would otherwise go to waste, and do multiple tasks in parallel. And there is a never before seen level of control over NVIDIA SLI and AMD CrossFireX configurations, which means that as a developer we can take full control over those systems and ensure users get a great experience with them.

According to the slide shown last year during the GDC 2015, NVIDIA VXAO is a tracing technique which is about three times lighter than conventional global illumination. Compared with SSAO (Screen space ambient occlusion), voxel-based ambient occlusion (VXAO) also offers a more stable throughput for rendering. NVIDIA VXAO provides a smoother response to camera motion, but it’s also computationally heavy. It’ll only work on Maxwell-based graphics card in DirectX 11 mode, however.

“The results of SSAO not always correct, such as when the geometry approaches the edge of the screen, or when distant objects are close together in the screen space. Ambient occlusion based on voxels no such problems “
