DirectX 12 Ultimate is the next step in Microsoft's API evolution for developing next gen games. Features such as DirectX Ray Tracing, Sampler Feedback, Variable Rate Shading, and Mesh Shading are now at the developers fingertips to include in their games much easier than before.
Ray Tracing is the big star though offering up realistic lighting, accurate shadows, and accurate reflections make it one of the big important steps in creating better looking games. I've been playing many games with Ray Tracing courtesy of NVIDIA. Full disclosure, they provided me with a GeForce RTX 2080 Ti for reviewing of various PC games in both traditional and VR space. Let me say that ray tracing really does make a big difference in some games providing a more realistic view of the game world.
Microsoft recently released the May 2020 update which included PC support for DirectX 12 Ultimate. Today's NVIDIA driver release provides NVIDIA owners support for DirectX 12 Ultimate with their hardware. They are the first to do so as well.
The May 2020 update also lets users turn on what's called Hardware-accelerated GPU scheduling whereby allowing the GPU to manage its own memory. This can possibly lead to performance benefits, but it is something you have to switch on manually in the Graphics Settings of Windows 10.
Finally, 9 more monitors have been validated as G-Sync compatible. They are as follows:
|Samsung||2020 Odyssey G9||49”||5120x1440|
|Samsung||2020 Odyssey G7||27”||2560x1440|
|Samsung||2020 Odyssey G7||32”||2560x1440|
So load up GeForce Experience and grab version 451.48 to reap the benefits.
