or does geeXLab need windows and cannot display directly onto the framebuffer?

GeeXLab for RPi exists in two versions: one with OpenGL 2.1 and one with OpenGL ES 2.0. GeeXLab with OpenGL 2.1 requires X11. GeeXLab for OpenGL ES 2.0 does not use a window manager, it renders the scene  directly in the framebuffer. Maybe you can try this version, and start GeeXLab and load scenes via command line.

In the code sample pack, you will find OpenGL ES 2.0 demos in the gles-20/ folder.

Palit GeForce GTX 1050 Ti KalmX Features:

- The first passive cooler for GTX1050 Ti in the market
- Two nickel plated heat pipes
- Vast volume of nickel plated fins
- Copper base with heat pipes for best heat dissipation from GPU to fins
- No external power required, good for small case PC
- Affordable GTX series product, great C/P value
- Great Hardware Components

Ok, I think recent drivers from NVIDIA and AMD come with serious changes in Vulkan API that can explain the crashes. I prefer that. I have to dive in my Vulkan code (GeeXLab) and hunt the bug! I will do this asap.

Parallel BSP traversal in compute shader, outputs sorted IB, transparent scene rendered in 1 drawcall.

- Demo description
- DX11 demo (source + exe)

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.

look - my comment about your ASUS GTX 1080 TURBO review. ;)

NOTE: sorry for wrong thread but I tried to send you this message in PM but this doesn't work. ::)

No problem. Yes I saw your message about the GTX1080 and the bad R376.09 driver...

Can it run without the windows manager? (no XWindows, directly from terminal)
I don't understand what do you mean. Do you mean you can start GeeXLab from the command line (with options)?

Can the whole screen resolution show nothing but the visual programmed? i looked at the demos and they all had descriptions on screen

Yes absolutely. All descriptions you can see on demos are just for information. You can control their rendering by code. Actually, you have to code the display of information, because GeeXLab does not do it for you. GeeXLab renders exactly what you have coded. It does not render things that you didn't code. Some demos use frameworks (like the kx framework) to make demos coding easier. But you are not forced to use them. You can code with the low level GeeXLab API (lua and python) or create your own framework/lib. You are free!

thanks for the report. I will test the Vulkan demos with a RX 470 asap!

Will it see the day of light?

Immersive gaming has never been more portable. Introducing Project Valerie, the world’s first automated triple display laptop. Constructed to be incredibly powerful yet mobile, this revolutionary laptop gives you easy access to three eye-popping 4K displays. Regardless of where you are, you can have the visual superiority of a 12K desktop setup to excel at both work and play.

CES 2017

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

... 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).

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.

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:

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.

Geeks3D's GPU Tools / Re: GTX 970 FurMark Crash
« on: December 23, 2016, 11:45:46 AM »
A GeForce GTX 970 has a power consumption around 150W - 200W. The Corsair V650 should do the job correctly.

If you toggle the torus rendering, the GPU power and GPU usage should drop significantly like on the following screenshots:
- torus rendering ON: GPU power: 101%TDP and GPU usage: 99%
- torus rendering OFF: GPU power: 20%TDP and GPU usage: 34%

Test system: GTX 1070 + R376.09 + win10 64-bit

And yes, when the furry torus is not rendered, the GPU has less to do. Maybe a driver issue...

3D-Tech News Around The Web / VFPR - a Vulkan Forward Plus Renderer
« on: December 20, 2016, 04:33:20 PM »
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.
