Doom Eternal's latest update now include Denuvo Anti-Cheat, not to be confused with Denuvo Anti-Tamper. Unlike Anti-Tamper, Anti-Cheat runs at the ring-0 kernel level of your PC. The Anti-Cheat can be uninstalled, however it is reportedly required to run Doom Eternal, even in singleplayer mode. One consequence of this new anti-cheat software is that it is now incompatible with Proton (Linux) and its ProtonDB rating has fallen from a previous Platinum award - to completely unplayable. Irdeto, the company that maintains Denuvo, has been working on this software for quite some time and it appears that Doom Eternal is the first game to use this software. This announcement about the software was made back in March 20, 2019: In this Doom Eternal announcement of May 14, 2020, they state: Check out our Denuvo wiki article which has been updated with information about Denuvo Anti-Cheat.

Hi, my name's Voxarp. I learned of PCGamingWiki from the late TotalBiscuit's videos back in the day and I used to help contribute from time to time but now days I'm mostly just a user. Thanks to everyone involved for providing such a great wiki! Recently Valve has introduced a new feature of SteamPlay called Proton which is a variant of WINE that allows Linux and possibly OSX to run Windows-only games. It's an exciting time! What the community seems to desperately need is a resource to: Report game compatibility, possibly with a WineDB type rating of Bronze/Silver/Gold/Platinum - right now all we have is a spreadsheet on Google Docs. Present fixes and workarounds for games that don't work out of the box. Provide clear delineation between Proton versions, a game might work properly on one Proton version but not another. Possibly provide an overview page with statistics on the percentage of games working, with a table that lets you sort by criteria such as Proton version or compatibility rating. I know this is a lot of effort and not to be taken lightly, but I feel it fits right in with PCGamingWiki's objective of providing fixes and workarounds for every single PC game.

A lot of interesting stuff has happened in February starting with the most important one. NVIDIA contributes to Nouveau once more Despite the status update report being published which mentions not only some new features which Nouveau received, it also appears that less and less people work on it but then, out of nowhere NVIDIA has stepped in and provided the following contributions to this project NVIDIA Format Modifiers - Provide better performance in compressed layers. Will be available in the upcoming Linux kernel 5.7 Signed firmwares for GeForce 16 series (1600 and 1650 series) While this is surprising nice approach it still lacks a specific firmware to deal with poor performance from GTX 900 series to newer and we have yet to receive an open source Vulkan driver which Nouveau still lacks. Mesa 20.0 has been released + 20.1 work has begun As stated in the title, Mesa 20.0 has been released which provides the following new features: Owners of Intel's Broadwell line of CPUs or newer will use the new Gallium3D driver codenamed Iris by default, providing better performance and take advantage of Gallium3D features such as the GalliumHUD or even Gallium3D Nine for use with Wine for a native DIrect3D 9 support (Requires Wine Nine Config) compared to the old i965 driver which is still used for older Intel iGPUs. Additionally Mesa 20.0 now supports Intel's Jasper Lake line of CPUs as well. Owners of AMD graphics card based on GCN 1.0/1.1 architecture can take advantage of Valve's shader compiler made specifically for AMD called ACO, reducing the shader compiling time (which in turn minimizes stuttering) and provide more FPS as a bonus. Speaking of ACO, it supports even more shaders and some improvements leaving only Tesselation shaders and OpenGL support for last. AMD's Gallium3D driver, RadeonSI, now supports OpenGL 4.6 due to the NIR being enabled and used by default and now uses the "live shader cache" to reduce the stuttering when compiling shaders in OpenGL games. The recently added Next-Gen Geometry added by AMD for Navi GPUs has been re-enabled. Previously was disabled due to the issues popping up that were difficult to fix. As of this release, the work on 20.1 version has begun and it's expected to receive a stable release in May 2020. So far these are the new features that has been presented: Shader Disk Cache support for Nouveau, to improve loading times in games when using NVIDIA GPUs with the open source driver NIR support + OpenGL 4.6 support for R600 Gallium3D driver used by AMD HD 2000 series to HD 6000 series. Disabling (and perhaps removal) of SISched support, as Valve's ACO already beaten it. Used as a shader compiler for OpenGL and Vulkan games. Performance improvements by Valve for GCN 1.0/1.1 based graphics cards. AMD's GPU Profiler and SQ Thread Trace support for RadV (Open source Vulkan driver for AMDGPU) made possible by Valve. Normally these features were used by AMD in their own drivers, especially in their own open source Vulkan driver codenamed AMDVLK. Smaller size for RadeonSI, but even more performance improvements in combination with two compiling options which are LTO and PGO, as mentioned here. Speculation: OpenGL 3.0 support in Zink, an OpenGL To Vulkan driver. Some oopsies have happenned It seems that Windows games that ran through Proton started to count as Windows sale instead of the Linux one for some time until a game developer noticed this, luckily this has been reported to Valve and turns out that despite the system of it works, the filtering did not. But now time to mention some major issue that is going on. As of the release of Linux kernel 5.5, it turns out that it missed some of the critical patches for Intel Graphics Driver which led to system freezes and other serious issues. Hopefully the point releases included them. Other news: - Besides the release of Godot Engine 4.0 happening in mid 2020, the developers announced that it will include Wayland support along with EGL support, which for latter's case will greatly help for Raspberry Pi devices. - Wine has reached 5.3 release - Proton reached 5.0 release - DXVK received 1.5.5 release which only includes bugfixes. New major release will happen once all the regressions have been fixed.

Hello and welcome into a Monthly Tux Gaming News which I mention what was going on in this month around the Linux gaming community which you won't find in any mainstream gaming news. Mesa 19.3 stable release delayed, further improvements en-route. Mesa, an open source GPU driver library maintained by the community has it's 19.3 stable version delayed to early December as there are more bugs to fill in. This will be the 1st release which will contain Valve's own shader compiler that is meant to replace LLVM, which is commonly used for this stuff specially when they are complex, with ACO which is specifically made for AMD graphics cards only . The major difference between these two is that ACO takes much less time to compile the shaders and as a bonus provides a frame rate boost, however it currently only works under Vulkan and you must be using Radeon RX 300 series or newer from dedicated GPU whereas in case of APUs it's Bristol Ridge, Raven Ridge or newer. You can learn more information about this feature from their blog post, they have plans to provide support for HD 7000 series and OpenGL along with other shading stages according to this roadmap. But that is not just it, Valve is revising their Secure Compile feature for Mesa's AMD Vulkan driver called RadV which will result in lower resource usage and avoid slower shader compile times reducing the stuttering even more and best of all, this gets backported into 19.3, so by combining that with ACO things will get even more interesting. However, ACO will not be enabled by default as it requires you to run the game with RADV_PERFTEST=aco on Steam you need to use this in launch parameter right at the beginning RADV_PERFTEST=aco %command% Next major release of Mesa will happen in February 2020 which will hit 20.0 and the work has already started. New AAA game Linux port from Feral Interactive + a major update for one of their older Linux ports Feral Interactive was busy this year with porting Shadow Of The Tomb Raider into Linux and Mac. The Linux version uses Vulkan by default and it's based on the DIrect3D 12 version of the game instead of D3D 11, what is the result you ask and how does it compare to Windows? First of all, there's no ray tracing support which can be a bummer, but when it comes to performance compared to Windows version, according to this following benchmark video the difference between them is that the native Linux version is......about 2% slower. That is seriously impressive, however there has been some words that on AMD GPUs in conjunction with ACO the game actually runs faster than NVIDIA but so far no benchmark has been found to confirm this. But this is not the only main thing that has been going on around from Feral, they've also updated their Linux port of Shadow of Modor by providing Vulkan support which currently is in beta and can be opted-in any time by choosing linux_vulkan_beta from Betas tab. As their older port uses OpenGL and was released in 2015 it had a worse performance compared to Windows as they were still new to porting games into Linux, after all, the company was primarily doing Mac ports since 1998 and started with Linux porting in 2014 with X-Com: Enemy Unknown. So, has this helped improving the performance? Considering how since 2016 where they've started playing around with Vulkan by choosing Mad Max i dare to say.... It's jawdropping! The most interesting thing here is that this is not the only thing that got added, Feral also added an option to choose the Vulkan driver of your choice and change the FOV through their launcher. Since Tomb Raider 2013 on Mac got a Metal support, perhaps that game will also receive the Vulkan treatment......or Deux Ex Mankind Divided? Actually, DX:MD seriously needs one. Valve still being busy and awesome with Linux support as usual Besides Mesa stuff, Valve has also been busy with their own stuff. They have activated VKD3D in their Proton 4.11-8 release which is Wine's own Direct3D 12 to Vulkan wrapper allowing you to play games which utilize D3D12, however be aware that this wrapper is still being worked on and speaking of Proton, the recent version that got hit at the end of this month is 4.11-9 which are just mostly bug fixes. One thing thou that received a major change from Valve for Steam is the option to use Steam Linux Runtime as a Compatibility Tool. What does it do? Well basically it forces the game to use the libraries which were included with Steam, including 32 bit ones. This is a very useful option as there is a chance that a native Linux game will not work be it missing a library or 32 bit games not working (Gee, wonder what made them to do it in a 1st place), game developers can also take the advantage of it as well when providing a help for the user that uses a distro not supported by Steam which is Ubuntu LTS or anything based on it or even use it for testing purposes. What else is there? Hmmmm....Oh, streaming option has been enabled on Steam for Linux, wonder what took em so long to do it. What's next in the future? Well after the release of Linux kernel 5.4, the next major version is still in the works and may end up in a freezing state soon, as mentioned previously Mesa 20.0 work has begun and finally perhaps things will get interesting once Ubuntu 20.04 hits in April 2020 which will be a Long Term Support one. "What about Nouveau, the open source NVIDIA driver by the community?" you ask. Still in a poor shape from 900 series and no Vulkan driver of it's own. Hope NVIDIA actually does something about this.
