Since the recommended features of OpenGL 3.x are not available on MacOS, Parallels simply has nowhere to translate them. ![]() ![]() ![]() The virtual machine converts Windows API calls to MacOS calls (the description is simplified, in fact, everything is more complicated). Parallels virtualized graphics for use with MacOS graphics cards use OpenGL. Therefore, almost all OpenGL applications for Windows use this profile. And if you are improving an old product, it is better to choose a compatibility profile. If you are creating a new application or engine from scratch, you can start from the main profile. And the solution is the compatibility profile. PARALLELS DESKTOP 13 CODEBut now he is forced to rewrite a bunch of old code so as not to use functions that are no longer available. The developer wants to use new features from OpenGL 3.x. Imagine the developer who created the Windows application that uses OpenGL 2.1. But Apple on MacOS only supports the main profile. PARALLELS DESKTOP 13 DRIVERSIn general, manufacturers of video cards in drivers for Windows support a compatibility profile so that older applications can work. In the main profile, non-recommended functions are not available they work in the compatibility profile. At that time, OpenGL introduced an additional version system called “Core profile / Compatibility profile”. Why? In OpenGL 3.0, many features from OpenGL 2 and earlier were flagged as not recommended and permanently removed in OpenGL 3.1. Why doesn't Parallels support OpenGL 4.1 on Windows? To confuse everyone even more, I will say that even some OpenGL 3.x Windows applications do not work in Parallels Desktop 13. In addition, you may notice that MacOS supports OpenGL 4.1, while Parallels Desktop 13 only supports OpenGL 3.2. For example, if an application needs OpenGL 3, and the operating system supports OpenGL 4, then it is logical to assume that the application will work just fine. OpenGL has more complex versioning than most other applications. Series Quake games (Quake, Quake II, Enemy Territory: Quake Wars and others.).Some more well-working OpenGL applications: Examples of OpenGL applications that work well in Parallels Desktop 13 are presented below.ĭIALux evo - The de facto standard in the professional lighting design industry. Thanks to the efforts of engineers, some Windows applications using OpenGL 3.2 began to work in Parallels Desktop 12 and 13. Parallels Desktop can allow your Mac to run most Windows applications, some games, and some CAD / CAM applications. PARALLELS DESKTOP 13 PCI’d like to tell you that Parallels Desktop magically transforms your four-year-old MacBook Air into a powerful $ 3,000 water-cooled PC gaming machine, but it’s not. OpenGL "is widely used in computer-aided design (CAD) systems, virtual reality, scientific and informational visualizations, flight simulators and video games."įor example, OpenGL uses Windows-based applications Adobe After Effects, Adobe Photoshop, Adobe Premiere Pro, Autodesk AutoCAD, Google SketchUp and a myriad of games. Typically used to interact with a graphics card for hardware rendering acceleration. “The Open Graphics Library (OpenGL) is a language-independent cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. In this article I will talk about OpenGL. Almost every major release of Parallels DesktopWe are trying to improve support for these libraries. Many Windows CAD / CAM applications and games use DirectX or OpenGL. Under the cut is a short story about why “owls are not what they really seem” (c).įor those Windows applications that use 3D graphics, two more factors must be taken into account: the performance of the video card and the graphic Windows libraries used by the application - DirectX or OpenGL. Many factors affect the speed of Windows applications running in the Parallels Desktop virtual machine: processor power, the availability of SSDs, running applications, Windows updates, and much more. PARALLELS DESKTOP 13 FOR MACEvery Parallels Desktop for Mac user wants Windows applications to run as fast as possible. ![]()
