Portal 2 Sees A Vulkan Renderer Added Via DXVK

Portal 2, Valve's puzzle platform game that has been around for a decade already, is now seeing Vulkan rendering support added by leveraging DXVK.

Portal 2 to date has supported OpenGL on Linux while Direct3D 9 has been available on Windows for this Source Engine game. Now though Valve is introducing Vulkan support not by moving to a newer version of the Source Engine but in integrating DXVK natively to allow optionally translating the Direct3D 9 path atop Vulkan.

With the "-vulkan" command line switch,

DXVK 1.8 Released With Support For More Direct3D Games

DXVK 1.8 is out as the newest feature release of this translation layer for Direct3D over Vulkan.

DXVK 1.8 now ensures CPU-based Vulkan implementations are enumerated last, optimized image layout transitions, DXGI multi-monitor support, improved D3D9 texture upload performance, and other Direct3D support improvements.

DXVK 1.8 also has fixes for games including Atelier Ryza 2, Battle Engine Aquila, Dark Messiah of Might & Magic, Everquest, F1 2018, F

GTK 4.2 Releasing Next Month With Likely Introducing A New OpenGL Renderer

While the GTK 4.0 toolkit just released in December, GTK 4.2 is already gearing up for release next month with GNOME 40.

While not merged quite yet, most notable to GTK 4.2 as the first GTK4 update is a new OpenGL renderer . This OpenGL renderer overhaul was driven in improving the macOS support where its OpenGL requirements are more strict than Linux. With GTK 4.0 is also the Vulkan renderer that is available to Linux users. The new renderer code hasn't been

F2FS With Linux 5.12 Lets You Configure The Zstd/LZ4 Compression Ratio

The Flash-Friendly File-System (F2FS) with the Linux 5.12 kernel will allow configuring the compression ratio when enabling the transparent file-system compression support with LZ4 or Zstd.

Jaegeuk Kim sent in the F2FS changes this week for the Linux 5.12 merge window. Most exciting is configurable compression ratio for its file-system compression rather than sticking to just the default compression level. When mounting a F2FS file-system with the " compress_algorithm "

HP ZBook Studio G7 Aims To Attract Linux Developers, Data Scientists

The HP ZBook Studio G7 aims to attract Linux developers and data scientists by not only offering a powerful hardware combination and by pre-loading Ubuntu 20.04 LTS but in also shipping a variety of tools and other software packages pre-configured for a modern developer and data scientist workload. We have been testing the HP ZBook Studio G7 for the better part of two months for this Linux-loaded mobile workstation and in this article is a look at this new HP device along with plenty of benchmarks,

Android 12 Developer Preview Released

The first public developer preview is out today of Android 12.

Among the changes that users and developers can look forward to with the forthcoming Google Android 12 include:

- Various trust/safety improvements around SameSite cookie behavior in WebView, safer handling of Intents, and other changes in the name of security.

- Compatible media transcoding support for apps not able to handle HEVC. For apps not capable of HEVC, automatic transcoding to AVC will be performed.

- AVIF image support is now in place, based on the

Linux 5.12 Hooks In LED Support To The TTY Layer

There is an interesting change with the TTY/serial changes for the in-development Linux 5.12 kernel.

With Linux 5.12 there is TTY LED support with new code added to the TTY core code and the kernel's LED layer. What is LED support around TTYs for with the Linux kernel? It's about allowing possible triggers. With the TTY triggers support, it's possible to configure the LEDs so that the TTY statistics will be periodically checked and if changed will cause the

NVIDIA Launching "CMP" Cards For Professional Mining, Limits RTX 3060 Mining Potential

NVIDIA is launching the CMP - the Cryptocurrency Mining Processor -- that will be a line of hardware focused on professional mining with an emphasis on Ethereum.

NVIDIA CMP products will not support graphics but are NVIDIA GPUs optimized for the best mining performance and efficiency. These initial mining-only cards are to be the NVIDIA CMP 30HX, 40HX, 50HX, and 90HX products with Ethereum hash rates from 26 MH/s to 86 MH/s and power consumption between 12

Linux 5.10.17 Backports CPUFreq Patches From 5.11 - Benchmarks

Released yesterday was the Linux 5.10.17 LTS kernel and what makes this point release a bit more notable than usual is that it backports the CPUFreq patches from 5.11 that were used for addressing the earlier AMD performance regression on Linux 5.11 and often leading to net improvements as well over prior kernel series. The CPUFreq patches were back-ported while the AMD frequency invariance support was not, so what does the performance look like for the Linux 5.10 LTS kernel?

Many Networking Improvements Routed To The Linux 5.12 Kernel

David Miller sent in the big batch of networking improvements today for the ongoing Linux 5.12 merge window.

As usual with Linux being widely used on enterprise networking equipment and hardware vendors being especially concerned about driver support with high-end hardware commonly running Linux in the data center, the networking subsystem updates are quite extensive and varied. Among the many networking changes landing with Linux 5.12 include:

- RFC6056 "Recommendations for Transport-Protocol Port Randomization" is now implemented for better port
