No all Steam games on Linux are Windows games running in WINE, many are truly ported. I've got the Borderland games and they are ports not running in WINE. Proton and WINE just extend selection for old games avoiding the need to port. And does that somehow lopside the bias of game count to make native Linux games far exceed those native games available on Windows? Of course not. A game that had been ported to be a native Linux app is obviously no longer a Windows app. A ported Windows game becomes a native Linux game. The count of Linux games, whether native or ported to make native, are still meager compared to the count of native games on Windows. Steam Play (Steam for Linux) detects the platform for the game probably via a manifest for the game specifying its native platform. If it's a native Linux game, it just loads it in Linux. If a Windows game, it uses its WINE variant (aka Proton) to run the Windows game in that emulator running atop Linux. https://www.extremetech.com/gaming/2...ows-only-games The confirmed list of Windows-only games that are compatible atop Steam's Proton variant of is small. That's just the ones that Steam has confirmed are compatible. https://emulation.gametechwiki.com/index.php/Proton has a hyperlink pointing to a list of app manifests/mappings for 100+ compatible Windows games. There's also a link to user-reported game compatibility. Proton converts the DX 10/11 calls to Vulkan to help keep game performance similar to the Windows game when ran native on Windows. That is dependent on the available of proprietary Linux drivers for video hardware, the efficiency in coding the Linux video driver, and compatibility of the Linux driver provided by the video maker to run on other Linux variants (most don't list just Linux but some variant as supported). Regardless of the workarounds, they still don't alter which are native Linux games and which are native Windows games, and the huge disparity in counts between them. As noted, you can run Linux stuff on Windows, but that doesn't magically mutate them into native Windows apps. Linux marketshare floats around 2%, so obviously the game authors are going to target the market that has the biggest ROI. That's not Linux. I'm not a Windows proselytizer or Linux defender. I believe in using the platform that best suits the task. Sorry, I still don't see Linux as the best choice for a gaming platform. |

What follows are "referrer" and "From", with another couple of URLs in there (with the "://"s and subsequent "/"s turned into their hex equivalents). is.gd, the URL shortening service that the OP used, does not provide a preview mode. With TinyURL, you can add the "preview" hostname to see where shortened URL points. Well, is.gd does have a preview mode, but it's clumsy. You go to: https://is.gd/previews.php click on the "... see preview page ...", leave the web browser open, and then click on the shortened URL the OP provided. Their page then shows the full original URL and, yep, it has all that crap in it. Or you can use on of the URL lengthener sites to reveal the original URL. I gave the full URL that the *OP* provided with the shortened version. Complain to the OP about not truncating URLs to their minimum. If he had, he would not have needed the URL shortening service. The full URL: https://www.pcgamer.com/linux-founde...real-problems/ is perhaps longer than the typical line length viewed in NNTP clients, but slicing up URLs that are longer than the logical (viewed) line length by injecting newlines (slicing URLs into multiple physical lines) is a defect of the sender's client. Physical lines can be up to 998 characters long (that's the old-time recommendation). Maybe some NNTP clients have problems when viewing physical line lengths longer than their viewable line length making the URL not clickable, and why I've seen some posters enclose the long URL within angle brackets, like URL, as a workaround for deficient clients. With some newsreaders, such as my old copy of Agent 2.0, brackets aren't a workaround for a deficient client. They are simply markers to let the composition window know that the configured line length value should be ignored for text between the brackets. |

Isn't Lutris a Linux game library manager and launcher, and perhaps across multiple sources (Steam, battle.net, GOG)? The video author says Lutris has no documentation. Really? Learning is solely by trial-and-error, or pleading for info in a user community? Before all that, he installed rpmFusion to get all the libs that Redhat doesn't include on which Lutris and Steam Play might be dependent. Install this, a must. Maybe install that. Then install Steam Play. I take it Lutris and Steam Play won't grab, download, and install any libs they are dependent upon.

Learn 'em, and let 'em choose. However, businesses and even schools need support from the OS vendor. Free doesn't include technical support. Those institutions don't look firstly at the cost of a license. They look for support and its cost. Not having robust support is costly. In-house training still has costs and adds delay to acquire expertise. Like buying a printer, you figure the Cost of Ownership is in the rate of use of the consumables (paper, ink), and lastly consider the cost of the printer. The cost of OS licenses is never discussed when we plan deployment of hosts, and supporting them. The loss of use for a critical business app or suite due to lack of support far exceeds free versus paid OS or software. Cobol programmers are in high demand ($75K/year average base pay), because colleges stopped teaching it long ago, so there aren't many Cobol programmers around after attribtion of old farts that have retired died off. Same for Fortran nowadays ($80K/year average base salary). Companies are willing to pay for the expertise that is hard to find. They couldn't give a gnat's fart about the costs for Cobol compiler licenses. Losing a critical business program due to no support costs way more, maybe even cause the company's demise. I have a sneaking suspicion that Microsoft is planning a migration to a Linux/Windows hybrid kernel with a Windows GUI. After all, Windows NT, and up, which had an NT-based kernel still carried along the familiar desktop GUI from the 9x/DOS frankenjob GUI. First it was Linux in their Azure cloud service. Then they began releasing apps for Android and Linux. They rolled in a Linux compatibility layer (Windows Subsystem for Linux, or WSL, but no Linux kernel code) to run Linux binary executables. Rolling in subsystems into Windows isn't new. NTFS is a file subsystem, as are FAT, exFAT, and CDFS. WSL v2 was announced May 2019 which moved to a real Linux kernel (as a subset of Hyper-V features). In 2016, WSL only provided an Ubuntu image. the Fall Creators Update in Oct 2017 move to SUSE images. With WSL v2 in May 2019, Linux support moved to a Hyper-V VM-based backend instead of the system-call adaption (compatibility) layer. We've been familiar with VMMs (Virtual Machine Managers) using virtual machines running guest OSes on Windows (or visa versa on Linux) for a long time. Microsoft decided to use the Hyper-V VMM. They wanted a kernel-mode model instead of user-mode solutions. Because of the extremely high adoption of Windows versus Linux, there has been concern that WSL could be a way for Microsoft to "embrace, extend, and extinguish Linux". At first, WSL was available only for Pro and Enterprise editions of Windows 10 x64. On July 2019, they granted its used on Home editions. I run optionalfeatures.exe (run with admin permissionsto effect changes), scroll down, and WSL is listed. I haven't yet played with WSL, so it's currently disabled. https://betanews.com/2018/03/06/debian-linux-windows/ "I am of the opinion that if you want to run an operating system based on that open source kernel, then you should just do so natively -- not on top of Windows." Well, that is not accurate. Hyper-V (a native hypervisor) is a VMM but it does *NOT* run in user-mode to manage VMs. It is a kernel-mode service. Probably because the Linux images are represented as "apps" in Microsoft's store is why that author thinks it is an app running atop of Windows. "Hyper-V implements isolation of virtual machines in terms of a partition." That's not a portion of an HDD or SDD where sectors are allocated in a group for use by an OS or data. That's a hypervisor partition. IBM mainframes 30+ years ago used similar hypervisors with OS isolation partitions. I was helping the sysadmin migrate to a new version of VSE, MVS, or VM by installing and configuring the new version of the OS in a different partition that was not accessible to the users. When we were ready, and late at night when the users were gone and after announcing the switch (because any users connected to the OS version in the old partition would get disconnected), we swapped which was the primary OS partition. The users came in and found a new version of the OS was ready. If there was a problem, we could switch back to the old OS partition. OS partition (Hyper-V) hierarchy https://upload.wikimedia.org/wikiped...px-Hyper-V.png Yes, every hypervisor is itself an OS, but the working Windows image and Linux image are not "running atop Windows". Users aren't using the Hyper-V OS for their work. They're using the VM of Windows managed by Hyper-V. Well, that's how it works for the server version. Only admins go into the Hyper-V OS to configure it. That's a distant memory since I haven't looked at Hyper-V for years. |

WSL v2 was announced May 2019 which moved to a real Linux kernel (as a subset of Hyper-V features). In 2016, WSL only provided an Ubuntu image. the Fall Creators Update in Oct 2017 move to SUSE images. With WSL v2 in May 2019, Linux support moved to a Hyper-V VM-based backend instead of the system-call adaption (compatibility) layer. We've been familiar with VMMs (Virtual Machine Managers) using virtual machines running guest OSes on Windows (or visa versa on Linux) for a long time. Microsoft decided to use the Hyper-V VMM. They wanted a kernel-mode model instead of user-mode solutions. Because of the extremely high adoption of Windows versus Linux, there has been concern that WSL could be a way for Microsoft to "embrace, extend, and extinguish Linux". At first, WSL was available only for Pro and Enterprise editions of Windows 10 x64. On July 2019, they granted its used on Home editions. I run optionalfeatures.exe (run with admin permissionsto effect changes), scroll down, and WSL is listed. I haven't yet played with WSL, so it's currently disabled. https://betanews.com/2018/03/06/debian-linux-windows/ "I am of the opinion that if you want to run an operating system based on that open source kernel, then you should just do so natively -- not on top of Windows." Well, that is not accurate. Hyper-V (a native hypervisor) is a VMM but it does *NOT* run in user-mode to manage VMs. It is a kernel-mode service. Probably because the Linux images are represented as "apps" in Microsoft's store is why that author thinks it is an app running atop of Windows. "Hyper-V implements isolation of virtual machines in terms of a partition." That's not a portion of an HDD or SDD where sectors are allocated in a group for use by an OS or data. That's a hypervisor partition. IBM mainframes 30+ years ago used similar hypervisors with OS isolation partitions. I was helping the sysadmin migrate to a new version of VSE, MVS, or VM by installing and configuring the new version of the OS in a different partition that was not accessible to the users. When we were ready, and late at night when the users were gone and after announcing the switch (because any users connected to the OS version in the old partition would get disconnected), we swapped which was the primary OS partition. The users came in and found a new version of the OS was ready. If there was a problem, we could switch back to the old OS partition. OS partition (Hyper-V) hierarchy https://upload.wikimedia.org/wikiped...px-Hyper-V.png Yes, every hypervisor is itself an OS, but the working Windows image and Linux image are not "running atop Windows". Users aren't using the Hyper-V OS for their work. They're using the VM of Windows managed by Hyper-V. Well, that's how it works for the server version. Only admins go into the Hyper-V OS to configure it. That's a distant memory since I haven't looked at Hyper-V for years. My experience has been different: When I was a youngster, the colleges trained on Apple. The minute grads hit industry, they switched to Windows. And my current experience with small business I have constantly tried to figure out how to get folks on Linux. It is virtually impossible, as the apps they need only run in Windows. It is the apps the customer cares about. They could care less if they were run int Flying Zucchini OS, if it ran their apps. I know this to be the case as my customer SELDOM know what OS they are running. Also, the recent computer science grads I have come across make my head spin. They know virtually nothing about computers or programming. Seriously, they barely know what a mouse is. And they are in debt up to the asses with student loans. |
