3D-Tech News Around The Web / Radeon GPU Profiler 1.0.1 (D3D12, Vulkan)
« Last post by JeGX on Today at 10:09:45 AM »
The Radeon GPU Profiler (RGP) is a ground-breaking low-level optimization tool from AMD.  It provides detailed timing information on Radeon Graphics using custom, built-in, hardware thread-tracing, allowing the developer deep inspection of GPU workloads.

This unique tool generates easy to understand visualizations of how your DirectX®12 and Vulkan® games interact with the GPU at the hardware level. Profiling a game is both a quick, and simple process using the Radeon Developer Panel and the public Crimson driver.

Supported GPUs:
- AMD Radeon R9 Fury and Nano series 
- AMD Radeon RX 400, RX 500 series

3D-Tech News Around The Web / Where do I start graphics programming?

Sometimes I get this question. And since it happens frequent enough, I decided I should write it publicly so that others can benefit, and also so I don’t have to repeat myself every time

In case you don’t know me, I’m self taught. I started doing graphics programming at age 14. My first experience was Visual C++ 6.0 and dived straight into C, C++ and assembly and came out just fine. The basics I learnt by reading a random PDF I found back then “Aprenda C++ como si estuviera en primero” (in Spanish) which was a very simple introduction to the language in 87 pages. What a variable is, what an enum is. How to do basic hello world.

Then I learnt a lot by trial and error. I started with several open source Glide Wrappers which were popular at the time. I used the debugger a lot to see line by line how the variables evolved. I would often remove some snippet of code to see what would happen if I took it out. I also played a lot with XviD’s source code.

Back then I had the DirectX SDK 7.0 samples and documentation to play with and I learnt a lot from it. In particular, Mathematics of Direct3D lighting fascinated me. I ended up writing my own TnL C library written in SSE assembly. It wasn’t very useful and I haven’t really updated it in more than a decade, but it helped a lot paving my foundations for when I came into contact with Vertex & Pixel Shaders. I was shocked that what took me an entire summer vacation and lots of assembly instructions (e.g. a matrix multiplication) could be done in one line of vertex shader code.

3D-Tech News Around The Web / Vulkan Synchronization Examples
« Last post by JeGX on Today at 08:19:24 AM »
Lot of synchronization examples are available here:

Synchronization in Vulkan can be confusing. It takes a lot of time to understand, and even then it's easy to trip up on small details. Most common use of Vulkan synchronization can be boiled down to a handful of use cases though, and this page lists a number of examples. May expand this in future to include other questions about synchronization.

Wait for the new GPU Caps Viewer 1.35.  I fixed many small bugs in the Vulkan code and it should run better with latest AMD Crimson drivers.

3D-Tech News Around The Web / CRYENGINE 5.4 Preview adds Vulkan support
« Last post by Stefan on July 27, 2017, 08:36:11 PM »
This week, the CRYENGINE 5.4 Preview is a major update which couldn’t have been achieved without all of the feedback from the community. There are several major advancements and integrations that we think will make things more accessible and let you achieve even more, more rapidly.


With over 623 improvements, fixes and features this release includes all new Vulkan API support, and although it’s our first step on the road you can expect further support on this soon. Also included is the Entity Component System with unified standard entities across C++ and Schematyc.


For Artists, we have a much requested Substance integration for the reading of material archives and manipulation of texture inputs with in-editor graphing. Additionally, we have expanded the feature set of the terrain system to allow for better blending of terrain and objects within your level.


Iterating on existing technology there is a second iteration of the Asset System which provides improvements and extended usage across tools, with thumbnail generation and all new dependency tracking. To get started, you can find the CRYENGINE 5.4 Preview on Github HERE!
