Quote
Back in the early days of consumer level 3D graphics hardware, BSP trees were a common component in rendering systems. Over time it fell out of fashion as the geometric complexity increased exponentially, scenes became more dynamic, and mesh data and processing moved over to the GPU side. With that said, BSP trees do have a number of desirable properties that made them attractive solutions for the static world geometry. One such property is that one can easily traverse a BSP tree in strict visibility order. If you don't have a depth buffer, you can render things correctly by traversing it back-to-front, and if you do have one, especially with Hi-Z rejection, you can instead traverse it front-to-back and get the maximum utilization of that hardware. Now this may not be a major concern today, but sorting things for transparency is still a problem we struggle to solve properly, and for static geometry a BSP tree can solve that quite elegantly.

CES 2017

A new shader stage has been added in the new Vega GPU architecture. This new stage is called primitive shader.

Quote
... the updated geometry engines will also feature one more advancement, which AMD is calling the primitive shader. A new shader stage that runs in place of the usual vertex and geometry shader path, the primitive shader allows for the high speed discarding of hidden/unnecessary primitives. Along with improving the total primitive rate, discarding primitives is the next best way to improve overall geometry performance, especially as game geometry gets increasingly fine, and very small, overdrawn triangles risk choking the GPU.

AMD isn’t offering any real detail here in how the primitive shader operates, and as a result I’m curious here whether this is something that AMD’s shader compiler can automatically add, or if it requires developers to specifically call it (like they would vertex and geometry shaders).

CES 2017

The power of Pascal-based GPU farms.

The new GeForce NOW service gives you instant access to a virtual GeForce GTX 1080 gaming PC in the cloud. It turns your Mac or PC into a high-performance GeForce gaming machine.

Quote
Want to play new PC games but have a macOS- or Windows-based machine that isn’t up to the task? Become an NVIDIA GeForce NOW™ user and get instant access to GeForce GTX 1080 gaming in the cloud to play the latest games in high-definition at maximum settings and smooth framerates.

GeForce NOW connects to the leading digital stores, which means you can install the platforms and the games you currently own on your virtual gaming PC in the cloud. You can even directly install free-to-play games. Whichever game you choose, GeForce NOW supports the standard features you’re used to, including multiplayer gaming, friends lists, chat, and achievements.

The GeForce NOW service has a cost:

Quote
Prices are tied to the virtual PCs’ GPUs. $25 will get you 20 hours on a GTX 1060, while the same amount of money buys 10 hours on a GTX 1080 PC. You'll get between four and eight free hours to start off with, and Nvidia says installing games doesn’t count toward play times.

3D-Tech News Around The Web / VFPR - a Vulkan Forward Plus Renderer
« on: December 20, 2016, 04:33:20 PM »
Quote
In this project, we created a Forward Plus (tiled forward) renderer in Vulkan using compute shader to deal with light culling.

Our implementation is ~1000% faster than regular forward renderer (tested in Vulkan) under the condition of 200 lights.

Yes, Vulkan is really powerful! We learned about Vulkan at SIGGRAPH 2016 at Anaheim, and decided to dive into it at our final project.

Recently we introduced the VK_NVX_device_generated_commands (DGC) Vulkan extension, which allows rendering commands to be generated entirely on the GPU.

Earlier this week, we added support for VK_NVX_device_generated_commands to our Windows and Linux release drivers.

Today we are releasing the ‘BasicDeviceGeneratedCommandsVk’ SDK GameWorks sample. We highly recommend reading the introductory Vulkan Device-Generated Commands article in addition to this blog post.

VK_NVX_device_generated_commands is available in R376.09.

Understanding concurrency (and what breaks it) is extremely important when optimizing for modern GPUs. Modern APIs like DirectX® 12 or Vulkan™ provide the ability to schedule tasks asynchronously, which can enable higher GPU utilization with relatively little effort.
