This page provides links to both general release drivers that support OpenGL 4.6, and developer beta drivers that support upcoming OpenGL features.
OpenGL 4.6 support is available for Windows and Linux in our general release drivers available here:
Windows
OpenGL for Macintosh enables your computer to display three-dimensional graphics using applications designed to take advantage of OpenGL. Mac Games are more real, more powerful, and more fun.To install OpenGL, double-click the 'Installer' icon in the 'OpenGL Install' folder and follow the on-screen instructions. Download OpenGL Extensions Viewer for Mac - A free and reliable software utility for Mac computers that provides info about your OpenGL 3D accelerator's extensions and API. 'gcc -o func2d func2d.c -framework carbon -framework OpenGL -framework GLUT' where func2d is the name of your application executable and func2d.c is the c file used. The imports required in case you don't have them are: OpenGL/gl.h OpenGL/glu.h GLUT/glut.h stdlib.h.
Linux
Windows driver version 426.02 and Linux driver version 418.52.18 provide new features for OpenGL developers to test their upcoming OpenGL applications.
Windows 426.02
Linux 418.52.18
NVIDIA provides full OpenGL 4.6 support and functionality on NVIDIA GeForce and Quadro graphics card with one of the following Turing, Volta, Pascal, Maxwell (first or second generation) or Kepler based GPUs:
The OpenGL 4.6 specifications can be downloaded from http://www.opengl.org/registry/.
For any bugs or issues, please file a bug through the developer website: https://devtalk.nvidia.com/
GPUs with the new Turing architecture have many new OpenGL extensions giving developers access to new features.

Every Parallels Desktop® for Mac user wants their Windows applications to run as fast as possible. There are many factors that contribute to the overall speed of a Windows application running in a Parallels Desktop virtual machine: the speed of the processor in your Mac®, the speed of the hard disk or SSD in your Mac, the macOS® you’re running Parallels Desktop in, the Windows OS installed in your VM, the amount of RAM you have allocated to the running VM*, and many more.
For a Windows application that does lots of complex or 3D graphics, we can add two other factors: the performance of the graphics card in your Mac, and the Windows graphics library that the application uses—DirectX or OpenGL.
Many Windows CAD/CAM applications and Windows games use DirectX or OpenGL. In almost every major release of Parallels Desktop, we try to improve the support for these two libraries. In this blog post, I will focus on OpenGL.
First, a little background:
“Open Graphics Library (OpenGL) is a cross-language, cross-platformapplication programming interface (API) for rendering 2D and 3Dvector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-acceleratedrendering.”
OpenGL is used “extensively in the fields of computer-aided design (CAD), virtual reality, scientific visualization, information visualization, flight simulation, and video games.”
–Wikipedia
Windows applications that use OpenGL include Adobe After Effects, Adobe Photoshop, Adobe Premiere Pro, Autodesk AutoCAD, Google SketchUp, and so many games that they can’t be listed here.
I wish I could tell you that Parallels Desktop can magically turn your four-year-old MacBook Air® into a high-end PC gaming rig with a $3,000 liquid-cooled graphics card, but that is never going to happen.
Parallels Desktop can enable your Mac to run most Windows applications, some games, and some CAD/CAM applications.
The hard work of the Parallels engineering team has resulted in a number of successes with Windows applications using OpenGL 3.2. In particular, the OpenGL work included in Parallels Desktop 13 resulted in some new applications running quite well in Parallels Desktop. Here are some videos of these successes, and a list of other OpenGL applications that work well with Parallels Desktop 13.
glView – An OpenGL benchmarking application. See Video 1. Also check out the following section on OpenGL Versions so that you can better understand the results of the benchmarking shown at the end of the video.
DIALux evo – The de-facto standard in the professional lighting design industry. See Video 2.
Wolfenstein: The Old Blood – A very popular first-person shooter from Bethesda Softworks. Here is a shortened video of a Wolfenstein: The Old Blood game session, playing in Parallels Desktop 13 on a Mac. See Video 3. You can see the entire session at full resolution (1920 x 1080, 1.06GB) here.
Here are some additional OpenGL applications that work well:
You might be wondering about OpenGL versions. OpenGL has a more complex versioning than most other software standards. For example, it would be quite reasonable to think if an application requires OpenGL 3 and the OS supports OpenGL 4, then the application will work just fine. But for OpenGL, it is not so simple.
In addition, you might have noticed that macOS supports OpenGL 4.1, but Parallels Desktop 13 only support OpenGL 3.2. Why doesn’t Parallels support OpenGL 4.1 in Windows? Reveal for mac. To add to the confusion, even some OpenGL 3.x Windows applications don’t work in Parallel Desktop 13.
In OpenGL 3.0, many OpenGL 2 or earlier functions were marked as deprecated and then removed completely in OpenGL 3.1. At that time, an additional versioning dimension called “Core/Compatibility profile” was introduced to OpenGL. The Core profile made deprecated functions unavailable, while the Compatibility profile kept them working. In general, GPU vendors supported the Compatibility profile in their drivers for Windows so that more older applications would work. In contrast, Apple chose to support only the Core profile in macOS.
Imagine a developer who has some Windows application created using OpenGL 2.1. Then the developer wants to use some new function from OpenGL 3.x. Now the developer will have to rewrite a lot of legacy code to stop using deprecated functions that are not available anymore. Nobody wants to do it (or at least do it gradually). So here comes a solution: the Compatibility profile.
If you’re developing a new application/engine from scratch, you could start with the Core profile. If you’re improving an old one, Compatibility profile is a better choice. That’s the reason why almost all OpenGL applications for Windows use Compatibility profile.
The Parallels virtualized graphics rely on OpenGL in macOS to actually do the work on GPU. The VM basically mirrors API calls made in Windows to macOS calls. (The actual process is slightly more complicated.) Since OpenGL 3.x deprecated functions are not available in macOS, Parallels has nothing to map these older functions to in the macOS. As a consequence, Parallels Desktop uses the Core Profile.
At the moment, Parallels supports OpenGL 3.2 Core Profile, and for some (highly conservative) applications it can do OpenGL 3.2 Compatibility Profile.
Unfortunately, there is no easy way to predict whether a particular Windows OpenGL application will work well in Parallels Desktop. If you are already a Parallels Desktop customer, just try it.
If you are not yet a Parallels Desktop customer, we have a trial version of Parallels Desktop that you can download and install. You can also get Windows 10 installed in Parallels Desktop 13 at no charge. So try out the application or game you’re interested in and see if it meets your performance needs. If it does, great! You can then purchase both Parallels Desktop and Windows to use that application. If it doesn’t, you have not spent any money.
In addition, we have a forum thread where people add the OpenGL applications that they would like to see supported.
Please let us know in the comments about your experiences with the performance of Windows applications in Parallels Desktop 13.

*Concerning RAM, more is not always better, as is commonly thought. When a customer allocates too much RAM to Windows, the Mac can be “starved” for memory, and then everything on the Mac struggles and runs slowly, including Mac applications and Windows applications running in Parallels Desktop.
