Yes there are probably different render paths for the different GPU architectures.

I just fixed a bug in the GeeXLab SDK related to the management of the swapchain and now GPU Caps Viewer as well as GeeXLab work fine!

Something has changed in Vulkan sync because Vulkan demos of GPU Caps Viewer do not work anymore  >:(

3D-Tech News Around The Web / AMD Vega GPU architecture whitepaper
« on: August 15, 2017, 11:17:00 AM »
Vega is the most sweeping change to AMD’s core graphics technology since the
introduction of the first GCN-based chips five years ago. The Vega
architecture is intended to meet today’s needs by embracing several
principles: flexible operation, support for large data sets, improved
power efficiency, and extremely scalable performance. Vega
introduces a host of innovative features in pursuit of this vision, which
we’ll describe in the following pages. This new architecture promises
to revolutionize the way GPUs are used in both established and
emerging markets by offering developers new levels of control,
flexibility, and scalability.

3D-Tech News Around The Web / vkDOOM3: Vulkan renderer for DOOM 3
« on: August 11, 2017, 02:59:18 PM »
vkDOOM3 adds a Vulkan renderer to DOOM 3 BFG Edition. It was written as an example of how to use Vulkan for writing something more sizable than simple recipes. It covers topics such as General Setup, Proper Memory & Resource Allocation, Synchronization, Pipelines, etc.

NOTE: For those just wanting to dive straight into the Vulkan code you can find it here... neo/renderer/Vulkan. Also you can just search for ID_VULKAN.


Geeks3D's GPU Tools / Re: GPU Shark 0.10.x released
« on: August 10, 2017, 03:28:45 PM »
GPU Shark is a standalone executable and is only shipped in a portable way. Then, just extract the archive where you want (as long as you keep the amd_ags_x86.dll in the same folder than GPUShark.exe) and launch GPU Shark. You can extract the zip archive in the C or D (or E...) drive, really where you want.

The 0x500 is an old error in the RPi version of GeeXLab. Since all demos work fine, I never took the time to fix it.  And indeed it has no relation with quit issue.

In the GL ES version, there is no window manager provided by Raspbian. I have had to code the low level keyboard and mouse management. That could explain why sometime for some reasons, GeeXLab does not respond correctly... The OpenGL 2.1 version does not have this issue because keyboard and mouse are managed by X11. I will try to improve input management of the GL ES version in one of the next updates.

The amd_ags_x86.dll is shipped with GPU Shark zip archive. Maybe this DLL was missing in the archive hosted by majorgeeks. Try to download GPU Shark from the official download link:

This DLL is only used when an AMD GPU is detected and it should not prevent GPU Shark from running properly on your system.

Let me know.

Geeks3D's GPU Tools / Re: GPU Caps Viewer 1.36.x released
« on: August 09, 2017, 04:08:16 PM »
I just added a new version v1.36.1.1 with custom color disabled. You can find the exe in the ZIP version of GPU Caps Viewer (GPU_Caps_Viewer_v2.exe).


Let me know.

Thanks for your feedback. I'm glad you found the solution!
I have a 2405FPW since at least 10 years and it works still perfectly.

ESC should be enough to quit GeeXLab on RPi. Which GeeXLab have you tested? The OpenGL ES or the OpenGL 2.1 ?

I recommend you the OpenGL 2.1 version (it requires raspbian jessie) because it creates a real X11 window you can move and close like any other windows.

Will try to fix this.

Falcor is a real-time rendering framework supporting DirectX 12 and Vulkan. It aims to improve productivity of research and prototype projects. Its features include:
- Abstracting many common graphics operations, such as shader compilation, model loading and scene rendering
- VR support using OpenVR
- Common rendering effects such as shadows and post-processing effects

Nope I can't because I no longer have the Quadro P5000. The only Quadro I have is the K4000. Will try to test the driver with it.

Yes #SwissNationalDay  ;)

3D-Tech News Around The Web / GLEW 2.1.0 with OpenGL 4.6 support
« on: August 01, 2017, 03:24:49 PM »
The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.

[07-31-17] GLEW 2.1.0 adds support for OpenGL 4.6, new extensions and minor bug fixes
