Double-checked with Android Oreo, performance decreased abysmal.
I'll re-check in 18 months with "Android Pudding"  ::)

3D-Tech News Around The Web / Sol-R: CUDA / OpenCL-based realtime ray-tracer

Sol-R is a CUDA/OpenCL-based realtime ray-tracer compatible with Oculus Rift DK1, Kinect, Razor Hydra and Leap Motion devices. Sol-R was used by the Interactive Molecular Visualiser project (http://www.molecular-visualization.com)

A number of videos can be found on my channel: https://www.youtube.com/user/CyrilleOnDrums

Sol-R was written as a hobby project in order to understand and learn more about CUDA and OpenCL. Most of the code was written at night and during week-ends, meaning that it's probably not the best quality ever ;-)

The idea was to produce a Ray-Tracer that has its own "personality". Most of the code does not rely on any litterature about ray-tracing, but more on a naive approach of what rays could be used for. The idea was not to produce a physically based ray-tracer, but a simple engine that could produce cool images interactively.

Take it for what it is! Sol-R is a lot of fun to play with if you like coding computer generated images.

Today we added a new Vulkan test to our 3DMark Android benchmarking app. The new API Overhead feature test lets you compare the performance of Vulkan and OpenGL ES 3.0 APIs on your Android smartphone and tablet.
 3DMark API Overhead feature test Vulkan is a new graphics API that provides high-efficiency, low-level access to modern GPUs in a wide variety of devices from PCs to smartphones. APIs like Vulkan make better use of multi-core CPUs to streamline code execution and eliminate software bottlenecks, particularly for draw calls.
Games typically make thousands of draw calls per frame, but each one creates performance-limiting overhead for the CPU. APIs with less overhead can handle more draw calls and produce richer visuals. The API Overhead feature test is an impartial test for comparing the performance of Vulkan and OpenGL ES 3.0.
The 3DMark API Overhead feature test measures API performance by making a steadily increasing number of draw calls. The result of the test is the number of draw calls per second achieved by each API before the frame rate drops below 30 FPS.
The purpose of the test is to compare the relative performance of different APIs on a single mobile device. The API Overhead feature test is not a general-purpose GPU benchmark, and it should not be used to compare different Android devices or to compare Android devices with Apple devices.
We recommend reading the 3DMark Technical Guide, which goes into more detail and explains the important differences between feature tests and benchmarks.
 Important notes on compatibility The OpenGL ES 3.0 part of the test requires Android 5.0 or later and a device that supports OpenGL ES 3.0.
The Vulkan part of the test requires Android 7.0 or later and a device that supports Vulkan.
Please note that devices that shipped with early Vulkan drivers may have performance and stability issues in this test. Vulkan performance can be much lower than expected, and the test can crash on devices with underdeveloped Vulkan drivers. Performance on these older devices may improve with future Android OS updates.
 Download 3DMark is a free Android benchmark app available from Google Play.

Looks like Nexus 6P with Nougat update August 2017 is impacted.
I'll re-check with Oreo later...

Dear demo coders: please provide JavaScript demos live, most people are too lazy to unzip them onto their phones...
