Desktop OpenGL ES 3.1 on Mali GPUs with Panfrost

Panfrost, the open source driver for Arm Mali Midgard & Bifrost GPUs now provides desktop, non-conformant OpenGL ES 3.1. Panfrost’s desktop OpenGL support is native, reducing CPU overhead. Applications can now make use of the hardware’s hidden features, like explicit primitive restart indices, alpha testing, and quadrilaterals.

Remograph, providers of products and services for the computer graphics, visual simulation and 3D modeling markets, announced the release of Remo 3D v2.10. Remo 3D is an effective OpenGL-based tool for creating and modifying 3D models intended for realtime visualization. The primary file format is OpenFlight. Remo 3D is currently available for Microsoft Windows 10/8/7 and Linux. This new version 2.10 of Remo 3D brings support for more keyboard shortcuts, improved macro handling, setting of relative external reference paths and other various fixes. The full list of new features and improvements can be found in the release notes on our website.

Beginning with Mesa 20.2 is OpenGL 4.5 support for LLVMpipe, the LLVM-based software rasterizer built as a Gallium3D driver. This succeeded LLVMpipe for years being limited to OpenGL 3.3. While the OpenGL 4.5 support has been enabled for weeks, The Khronos Group has now officially confirmed its implementation.

Intel OpenGL/Vulkan Linux Drivers Strike Another Optimization For Tiger Lake

Intel merged a change to benefit Intel’s Iris Gallium3D (OpenGL) and ANV Vulkan drivers for making use of the HDC data cache for uniform buffer object (UBO) pulls on Gen12+ hardware, namely Tiger Lake at this point. By making use of the data cache for UBO pulls, there is generally up to another few percent improvements for various OpenGL and Vulkan games running on Linux—either natively or through the likes of the DXVK layer. Some improvements cited in the merge include:

  • GTA V DXVK 104.0%
  • Talos Principle GL 102.8%
  • Rise of Tomb Raider VK 102.8%
  • Dark Souls 3 DXVK 101.4%
  • Witcher3 DXVK 101.3%
  • Bioshock Infinite GL 100.5%
  • Doom 2016 VK 97.7%

GPUOpen Series: Porting “Detroit: Become Human” from Playstation 4 to PC - Part 1

This blog series discusses the port of the game Detroit: Become Human  from PlayStation® 4 to P and is written jointly by Ronan Marchalot, 3D engine director, and 3D engine senior developers Nicolas Vizerie and Jonathan Siret from Quantic Dream, along with Lou Kramer, who is a developer technology engineer from AMD.  The first instalment in this series walks the reader through choosing an API: Already having an OpenGL working version, the choice is between Direct X 12 and Vulkan. Read the post to learn which was chosen.

Jet Set Vulkan : Reflecting on the move to Vulkan

Atypical Games, with support from Samsung, took on the task of implementing Vulkan support into their engine. In this blog, Razvan Baraitaru, Atypical Games, will share his experiences with porting to Vulkan and then later Calum Shields, Samsung, will discuss some of the issues that cropped up in the Android implementation of “Sky Gamblers: Infinite Jets”. There are numerous reasons for choosing Vulkan. Primarily it creates an opportunity for better performance and compatibility across many of our target platforms - Android, Nintendo Switch and Windows. Also, we had in mind some possible future Stadia games where Vulkan is the only graphics API.

Deep dive into OpenGL over DirectX layering

Earlier this year, Collabora announced a new project with Microsoft: the implementation of OpenCL & OpenGL to DirectX translation layers. Here’s the latest on this work, including the steps taken to improve the performance of the OpenGL-On-D3D12 driver.

NVIDIA provides OpenGL-accelerated Remote Desktop for GeForce

In these days of social distancing, game developers and content creators all over the world are working from home and asking for help using Windows Remote Desktop streaming with the OpenGL tools they use.

NVIDIA has created a special tool for GeForce GPUs to accelerate Windows Remote Desktop streaming with GeForce drivers R440 or later.

Download and run the executable (nvidiaopenglrdp.exe) from the DesignWorks website as Administrator on the remote Windows PC where your OpenGL application will run. A dialog will confirm that OpenGL acceleration is enabled for Remote Desktop and if a reboot is required.
