Updated Portal 2 Vulkan Rendering Code Yielding Great Radeon Results

Filed under

Valve on Monday rolled out a new Portal 2 build that improves its new Vulkan renderer support. For those interested here are some fresh benchmarks of Portal 2 with OpenGL and Vulkan on the open-source AMD Radeon Linux drivers.

In February was the surprise announcement of Vulkan rendering API support for Portal 2. Valve is making use of Vulkan with Portal 2 by leveraging the DXVK native library for translating the game's existing Direct3D 9 usage to Vulkan. The existing OpenGL support for Portal 2 on Linux remains available.

Valve yesterday released their first significant Portal 2 update since the initial Vulkan rendering support last month. Some of the specific improvements in this latest Portal 2 update include "massively improved" performance for multi-sample anti-aliasing (MSAA) with AMD graphics hardware, overall performance improvements, and a large number of bug fixes -- including many Linux-specific fixes.

AMDs AMDVLK Vulkan Driver For Linux...

  • AMDs AMDVLK Vulkan Driver For Linux Remains Horribly Slow At Compute Compared To The Mesa RADV Driver

    AMDVLK v-2021.Q1.4, released late last week, was a huge yawn with a Mad Max specific performance quirk and the API verison updated to Vulkan 1.2.169. The last half dozen releases were equally boring. It is therefore not shocking that the performance-differences between the AMD AMDVLK Vulkan driver and the Mesa RADV driver are the same today as they were half a year ago: The graphics performance is near-identical, with AMDVLK being slightly slower, while the gap between their respective compute performance remains significant.


    The MSI Kombustor TessMark benchmarks are clearly doing something the AMDVLK is incapable of handling at acceptable framerates. This is the only test where there is such a gigantic difference so it will probably not matter in the vast majority of games and applications but there could be some that do the same thing - with a huge performance-penalty as a result.

    Basemark GPU v1.2.3 tell as similar story of two nearly equal Vulkan drivers. The Mesa RADV driver has a one frame per second advantage at 4K, so it does get the higher score. The minimum and maximum values are exactly the same in both cases and practical difference just isn't there.

  • What is Raspberry Pi 4 “Model B”? [Ed: I'm still waiting for them to formally apologise for going behind customers' backs, making secret deals with Microsoft to put Microsoft malware on all those devices]

    Raspberry Pi has conquered the world of SoC (System on a Chip). It has already garnered millions of followers since its release in 2012. Not only is it inexpensive, but it’s also versatile, modular, and multi-purpose. It has become popular not only as a credit-sized computer board but also as a controller in electronic, robotics, and IoT projects. The size, features, and price drive the popularity of the Pi, especially in the DIY community. To keep up with the current technological trends, the tiny board has undergone plenty of upgrades over the years, and there have been many varieties so it can cater to the needs and demands of its users. In 2019, the Raspberry Pi Foundation released the fourth generation of the multi-purpose board, the Raspberry Pi 4 B. It is the most powerful Pi to date, sporting huge upgrades from its predecessors. The compact board is touted to deliver a PC-level performance, and it didn’t disappoint.

  • Kentaro Hayashi: Grow your ideas for Debian Project

    There may be some "If it could be ..." ideas for Debian Project. If idea is concreate and worth to make things forward, it should make a proposal for Project Funding. [...] I'm not confident whether mechanism works, but Debian needs change.

  • Sam Thursfield: Calliope, slowly building steam

    There are some interesting complexities to this, and in 12 hours of hacking I didn’t solve them all. Firstly, Bandcamp artist and album names are not normalized. Some artist names have spurious “The”, some album names have “(EP)” or “(single)” appended, so they don’t match your tags. These details are of interest only to librarians, but how can software tell the difference? The simplest approach is use Musicbrainz, specifically cpe musicbrainz resolve-ids. By comparing ids where possible we get mostly good results. There are many albums not on Musicbrainz, though, which for now turn up as false positives. Resolving Musicbrainz IDs is a tricky process, too — how do we distinguish Multi-Love (album) from Multi-Love (single) if we only have an album name? If you want to try it out, great! It’s still aimed at hackers — you’ll have to install from source with Meson and probably fix some bugs along the way. Please share the fixes!

  • Neovide Is A Graphical Neovim Client Written In Rust

    Neovide is a really cool GUI client for Neovim. Although it essentially functions like Neovim in the terminal, Neovide does add some nice graphical improvements such as cursor animations and smooth scrolling. It even has me thinking about making it my new "vim" alias.

Get involved with Mageia, become a Packager

With Mageia 8 just released and development for Mageia 9 getting underway in Cauldron, the unstable branch of Mageia, now is a great time to get involved with packaging. We are starting to look at the features that we want to include for Mageia 9, and as it is so early in the development cycle, now is the time for major developments, or big updates to key pieces of software. This is a great time to join the project as you can propose features you would like to see, help to implement large changes or see how a distribution evolves through development, stabilisation and then is released. If there is an application that you are interested in, if you want to help maintain part of the distribution, or if you want to learn something new, there are many opportunities to do so with the packaging team.

Google does not want you to tell your players about your donation page

I recently updated Pixel Wheels banner image on Google Play. That triggered a review of the game: shortly after the update I received a message telling me Pixel Wheels was "not compliant with Google Play Policies". What nefarious activity does the game engage in? Sneak on users? Mine bitcoins? [...] Meanwhile you can still get the game from F-Droid or, since they do not have a problem with a link to a donation page. Read more
