Raspbian Jessie Updated with a new Desktop Environment called PIXEL

Published May 6, 2017

Raspbian PIXEL desktop environment

The Raspberry Pi team has released a new version of Raspbian Jessie that comes with a new desktop environment called PIXEL. PIXEL stands for Pi Improved Xwindows Environment, Lightweight. PIXEL follows OS X or Windows 10 desktop with a flat-design approach.

Jessie has an OpenGL 2.1 driver and the version is still 2.1 Mesa 11.1.0 like on previous Jessie versions.

This new version of Raspbian packs some nice wallpapers to customize a bit the desktop:

The web browser of the previous versions of Raspbian Jessie has been replaced by Chromium. This is very cool because, I can now watch youtube videos on the RPi, thing that I was not able to enjoy with the old browser. The Chromium browser comes with 2 extensions: the h264ify (which forces YouTube to serve videos in a format accelerated by the RPi hardware) and an ad blocker: uBlock Origin.

This update of Raspbian brings a modern look to the desktop but I felt a kind of sluggishness (I tested Jessie/PIXEL on a Raspberry Pi 3): the system is not as fast as the previous version of Jessie and is often hung for several seconds. I hope a next update will improve my Jessie PIXEL experience.

Update (2016.10.28): it looks like the microSD (a Transcend Ultimate 16GB) card was the root of all sluggishnesses and hangs. I use this card since one year with the Raspberry Pi and the card has probably reached its limit in matter of read/write operations (I compile GeeXLab directly on the microSD card which can be an explanation).

I replaced the Transcend 16GB by a new Samsung 32GB EVO Plus (read: 80MB/s, write 20MB/s) and the new Raspbian with PIXEL works like a charm!

GPU Caps Viewer 1.34.0 Released

Published May 6, 2017

A new version of GPU Caps Viewer (OpenGL, Vulkan, OpenCL and CUDA utility) is available.

GPU Caps Viewer 1.34.0 Released

1 – Overview

GPU Caps Viewer 1.34.0 adds the support of the latest GeForce GTX 1080 Ti, Radeon RX 580, RX 570 and RX 560 (based on Polaris 10/11 GPUs) as well as Radeon Pro WX 7100, WX 5100 and WX 4100.

New Vulkan and OpenGL demos (based on GeeXLab engine) have been added in the 3D demos panel:

GPU Caps Viewer 1.34 + new GeeXLab demos

All GeeXLab demos can now be launched using the command line:



GpuCapsViewer.exe /demo_win_width=1920 /demo_win_height=1080

/demo_fullscreen /run_gxl_demo=vk_shadertoy_geomechanical

/benchmark_log_results /benchmark_duration=10000 /demo_msaa=0

/vk_gpu_index=0

Command line parameters can be found in the _run_geexlab_benchmark.bat file available in GPU Caps Viewer folder. The benchmark results are saved in a CSV file (_gxl_benchmark_results.csv).

Another change brought to GPU Caps concerns the UAC (User Account Control) execution level that has been reset to the default value (as invoker). The previous UAC level (administrator) didn’t work well with launching demos via the command line.

GPU Caps Viewer 1.33 + GeForce GTX 1060

All Vulkan code has been recompiled with latest Vulkan headers (v1.0.45).

>> Update: 2017.04.29 <<

GPU Caps Viewer 1.34.3.1 is a maintenance release and comes with a new VK-Z version. VS2015 generates some strange patterns in the 32-bit version of VK-Z and no matter the way I compile VK-Z, the 32-bit version of VK-Z is still flagged as infected by some antivirus. The 64-bit version of VK-Z is clean so I just replaced the 32-bit version by the 64-bit one. GPU Caps Viewer has been updated to execute VK-Z x64 on Windows 64-bit only…

>> Update: 2017.04.26 <<

GPU Caps Viewer 1.34.3.0 is a maintenance release and improves the detection of recent AMD Radeon GPUs (RX 580, RX 570, RX 480 and RX 470). GPU Shark has been updated to version 0.9.11.4. VK-Z has been updated to version 0.6.0.5 32-bit (it has been recompiled with other compilation options in order to avoid false positive detection with antivirus. I really don’t understand this pesky problem!).

>> Update: 2017.04.16 <<

GPU Caps Viewer 1.34.2.1 is available with VK-Z 0.6.0.3. The previous 32-bit version of VK-Z was detected as infected by some antivirus scanners. Now VK-Z 32-bit is clean for Nod32, Avira, Avast, Kaspersky, AVG, Norton, and MacAfee.

>> Update: 2017.04.14 <<

GPU Caps Viewer 1.34.2.0 adds the support of NVIDIA TITAN Xp. GPU Shark and VK-Z have been updated to their latest versions.

>> Update: 2017.04.01 <<

GPU Caps Viewer 1.34.1.0 improves the detection of AMD Radeon GPUs in some systems that include Intel iGPU + AMD Radeon GPU. A new GeeXLab/OpenGL demo has been added (Alien Corridor).

GPU Caps Viewer 1.34.1

2 – Dowloads

2.1 – Portable version (zip archive – no installation required):

2.2 – Win32 installer:

For any feedback or bug report, a thread on Geeks3D forums is available HERE.

3 – What is GPU Caps Viewer?

GPU Caps Viewer is a graphics card information utility focused on the OpenGL, Vulkan, OpenCL and CUDA API level support of the main (primary) graphics card. For Vulkan, OpenCL and CUDA, GPU Caps Viewer details the API support of each capable device available in the system. GPU Caps Viewer offers also a simple GPU monitoring facility (clock speed, temperature, GPU usage, fan speed) for NVIDIA GeForce and AMD Radeon based graphics cards. GPU data can be submitted to an online GPU database.

Impressive Pixel Shader of a Snail (GLSL)

Published March 16, 2016

Impressive Pixel Shader of a Snail (GLSL)

The wizard behind Shadertoy has struk once again with this beautiful demo showing an animated snail. This demo has been ported to GeeXLab by our news hunter Stefan.

The demo is available in the code samples pack in the host_api/GLSL_ShaderToy/ folder (snail_gl2.xml). The demo is also available in the X-MAS 15 pack HERE. To test the demo, just run GeeXLab (you can download the latest version from THIS PAGE) and load (or drag and drop) the demo (snail_gl2.xml) into GeeXLab (GeeXLab 0.9.2.0 is recommended).

This demo has been ported to GeeXLab by our news hunter Stefan

I quickly benchmarked few GPUs with this demo. The default settings are 800×480 pixels in windowed mode. The anti-aliasing can be set directly in the pixel shader and is equal to 1 by default (line 30 in the snail_gl2.xml file). A value of 4 improves the visual quality but destroys the framerate ? (try for yourself). I benchmarked with AA=1.

Testbed: Core i5 6600K, ASUS Z170 Pro Gaming, 8GB DDR4 Corsair Vengeance, Win10 64-bit, all hardware with stock clock speeds.

The demo runs fine without artifacts on an Intel HD Graphics 530!

Radeon R9 290X (Crimson 15.12)	89 FPS (avg)
GeForce GTX 960 (R361.43)	45 FPS (avg)
HD Graphics 530 (v4326)	10 FPS (avg)

A time lapse of the creation process of this demo with Shadertoy is available here:

Direct3D 12 vs OpenGL: A quick Test

Published March 16, 2016

Direct3D 12 vs OpenGL: A quick Test

GeeXLab, the successor of GLSL Hacker, comes with the support of Direct3D 12. It’s not a full support but most of the basic things are available: command lists (CL), pipeline state objects (PSO), constant buffers (CB) and HLSL shaders.

An introduction to Direct3D programming with GeeXLab is available HERE.

Since GeeXLab is now available with an OpenGL and a Direct3D 12 renderers, here is a quick benchmark that shows the difference of performance between Direct3D 12 and OpenGL 3.2 in a very simple scene: a phong-textured mesh (a torus to be original) is rendered with various polygon density. This test uses one command list, one PSO, one HLSL program, one mesh and one texture.

You can download both GeeXLab (version 0.9.3.0+ is recommended) and the test from THIS PAGE. The test is available in the host_api/Direct3D12_vs_OpenGL/ folder of the code sample pack (files: 09-lighting-mesh-d3d12.xml and 09-lighting-mesh-gl32.xml).

You can change the number of polygons by editing the source code of both files: lines 76-84 (09-lighting-mesh-d3d12.xml) and 47-54 (09-lighting-mesh-gl32.xml).

The results of this test should be taken with caution because it’s my first implementation of a Direct3D 12 plugin for GeeXLab and graphics drivers are also constantly updated. I will update this post as soon as I find bugs or bring some optimizations in GeeXLab that can change the results.

Testbed:

CPU: Intel Core i5 6600K @3.5GHz
Motherboard: ASUS Z170 Pro Gaming
RAM: 8GB DDR4 Corsair Vengeance
OS: Windows 10 64-bit
Drivers:
- Radeon R9 290X: Catalyst 15.10 beta
- GeForce GTX 970: R358.50
- HD Graphics 530: v4279

Clock speeds: stock values for the CPU, memory and graphics cards.

The FPS in the following tables are the average framerates.

Direct3D 12 vs OpenGL - benchmark results

According to this test, Direct3D 12 is faster than OpenGL when the number of triangles is low. AMD Radeon cards are particularly fast! Around 80K polygons, Direct3D offers the same kind of performance than OpenGL. Above 80K polygons, OpenGL is faster. The case of Intel GPU is interesting because it has more or less the same performances in D3D12 and GL. What’s more for a mesh of 2-million polygons, The Intel GPU is faster than a GTX 970 or a R9 290X in D3D12! It looks like for many polygons, there is a CPU-bottleneck somewhere in the D3D12 rendering pipeline that does not reflect the real power of GPUs.

The results are similar with latest drivers (R361.43 / Crimson 15.12).

I also did a simple draw stress test: a quad is rendered 100, 400 and 4000 times. No hardware instancing is used, each quad is rendered with its own draw call. I only tested on my dev system, with a GeForce GTX 960 + R361.43.

The test is available in the host_api/Direct3D12_vs_OpenGL/ folder of the code sample pack (files: 08-drawstress-d3d12.xml and 08-drawstress-opengl.xml).

In this test, a quad is made up of 4 vertices and 2 triangles.

To change the number of quads, edit the xml file and look for the lines:

quads = {x=10, y=10, size=10.0} -- 100 quads
--quads = {x=40, y=10, size=10.0} -- 400 quads
--quads = {x=100, y=40, size=10.0} -- 4000 quads

Direct3D 12

Num quads	GeForce GTX 960 (R361.43) (avg FPS / GPU load)
100	2900 / 20%
400	1070 / 26%
4000	180 / 20%

OpenGL 3.2

Num quads	GeForce GTX 960 (R361.43) (avg FPS / GPU load)
100	1840 / 58%
400	730 / 30%
4000	97 / 20%

GeeXLab is maybe not the best tool for this kind of test (a loop with 4000 iterations) because of the overhead of the virtual machine (Lua and host API functions calls). A C/C++ based test should be better. But this GeeXLab test shows that we can draw more objects with Direct3D 12 than with OpenGL. This is particularly visible with 4000 quads: D3D12 is twice faster: 180FPS for D3D12 against 97 FPS for OpenGL.

What’s New in OpenGL 4.5 and OpenGL Shading Language 4.5

Published March 1, 2016

The OpenGL 4.5 and OpenGL Shading Language 4.50 Specifications were released on August 11, 2014.

New features of OpenGL 4.5 include:

Direct State Access (DSA)
object accessors enable state to be queried and modified without binding objects to contexts, for increased application and middleware efficiency and flexibility;
Flush Control
applications can control flushing of pending commands before context switching – enabling high-performance multithreaded applications;
Robustness
providing a secure platform for applications such as WebGL browsers, including preventing a GPU reset affecting any other running applications;
OpenGL ES 3.1 API and shader compatibility
to enable the easy development and execution of the latest OpenGL ES applications on desktop systems;
DX11 emulation features
for easier porting of applications between OpenGL and Direct3D.

New extensions to OpenGL 4.5 include:

GL_ARB_clip_control
GL_ARB_cull_distance
GL_ARB_ES3_1_compatibility
GL_ARB_conditional_render_inverted
GL_KHR_context_flush_control
GL_ARB_derivative_control
GL_ARB_direct_state_access
GL_ARB_get_texture_sub_image
GL_KHR_robustness
GL_ARB_shader_texture_image_samples
GL_ARB_texture_barrier
