3D-Tech News Around The Web / MTuner: Advanced C/C++ Memory Profiler
« on: August 24, 2017, 01:10:54 PM »
MTuner is a C/C++ memory profiler and memory leak finder for Windows, PS4, PS3, etc.

MTuner utilizes a novel approach to memory profiling and analysis, keeping entire time-based history of memory operations. This gives an unique insight in memory related behavior of your software by making queries over the entire data set.


V1.02 Changes

    Radeon GPU Profiler

    Added Vega support
    Added web browser-style navigation
    Keyboard navigation improvements
    Improvements to the System Activity frame visualization and frame duration data
    Select next/previous event in event timeline if the event hasn't been filtered out
    Treat SetMarker user markers as points in time and don't associate the next event with them
    Fix the ruler from disappearing when zoomed in on a 4K display
    Fix displaying of memory sizes in the Device configuration. Auto adjust to display memory units depending on memory size
    View dragging issues fixed
    Prevent loading of profiles created on unsupported hardware. The data will be unreliable if shown
    Bug/stability fixes & UI clean ups

    Radeon Developer Panel

    Linux Ctrl-C (SIGINT) handler added to RadeonDeveloperPanel and RadeonDeveloperService for clean shutdown
    Don't allow the user to attempt another connection while attempting a connection
    Extend Linux hotkey keyboard device support
    Improve application blacklist support - don't try to attach to known applications
    Fixes for connection timeout countdown issue
    Allow profiling using peak clock mode
    Miscellaneous bug/stability fixes


Crimson 17.8.1 exposes OpenGL 4.5 + Vulkan 1.0.51 like Crimson 17.7.2.

Internal OpenGL version is now while it was in Crimson 17.7.2.

Intel 8th generation processors based on Coffee Lake architecture will be launched tomorrow (August 22, 2017). Here is a quick overview of the specifications as well a preview of the retail boxes:

Mobile CPUs are launched today:

- Intel Launches 8th Generation Core CPUs, Starting with Kaby Lake Refresh for 15W Mobile
- Intel 8th Gen Core i5 and Core i7 Retail Boxes Pictured

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 (

A number of videos can be found on my channel:

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.


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.

This new Vulkan SDK release includes the following updates:

    A new Device Simulation Layer that allows JSON configuration of device-reported limits and capabilities
    New options in spirv-opt to reduce SPIR-V binary size
    New Vulkan extensions introduced since the 1.0.54 SDK:
    Updates to loader, layers, and documents to reflect new extensions and changes defined in Vulkan version
    Scores of bug fixes and validation coverage improvements

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.
