OpenGL is an open, cross-platform graphics standard with broad industry support. OpenGL greatly eases the task of writing real-time 2D or 3D graphics applications by providing a mature, well-documented graphics processing pipeline that supports the abstraction of current and future hardware accelerators.
At a Glance
OpenGL is an excellent choice for graphics development on the Macintosh platform because it offers the following advantages:
- Reliable Implementation. The OpenGL client-server model abstracts hardware details and guarantees consistent presentation on any compliant hardware and software configuration. Every implementation of OpenGL adheres to the OpenGL specification and must pass a set of conformance tests.
- Performance. Applications can harness the considerable power of the graphics hardware to improve rendering speeds and quality.
- Industry acceptance. The specification for OpenGL is controlled by the Khronos Group, an industry consortium whose members include many of the major companies in the computer graphics industry, including Apple. In addition to OpenGL for OS X, there are OpenGL implementations for Windows, Linux, Irix, Solaris, and many game consoles.
OpenGL Is a C-based, Platform-Neutral API
Because OpenGL is a C-based API, it is extremely portable and widely supported. As a C API, it integrates seamlessly with Objective-C based Cocoa applications. OpenGL provides functions your application uses to generate 2D or 3D images. Your application presents the rendered images to the screen or copies them back to its own memory.
The OpenGL specification does not provide a windowing layer of its own. It relies on functions defined by OS X to integrate OpenGL drawing with the windowing system. Your application creates an OS X OpenGL rendering context and attaches a rendering target to it (known as a drawable object). The rendering context manages OpenGL state changes and objects created by calls to the OpenGL API. The drawable object is the final destination for OpenGL drawing commands and is typically associated with a Cocoa window or view.
Different Rendering Destinations Require Different Setup Commands
Depending on whether your application intends to draw OpenGL content to a window, to draw to the entire screen, or to perform offscreen image processing, it takes different steps to create the rendering context and associate it with a drawable object.

OpenGL on Macs Exists in a Heterogenous Environment
Macs support different types of graphics processors, each with different rendering capabilities, supporting versions of OpenGL from 1.x through OpenGL 3.2. When creating a rendering context, your application can accept a broad range of renderers or it can restrict itself to devices with specific capabilities. Once you have a context, you can configure how that context executes OpenGL commands.
OpenGL on the Mac is not only a heterogenous environment, but it is also a dynamic environment. Users can add or remove displays, or take a laptop running on battery power and plug it into a wall. When the graphics environment on the Mac changes, the renderer associated with the context may change. Your application must handle these changes and adjust how it uses OpenGL.

OpenGL Helps Applications Harness the Power of Graphics Processors
Graphics processors are massively parallelized devices optimized for graphics operations. To access that computing power adds additional overhead because data must move from your application to the GPU over slower internal buses. Accessing the same data simultaneously from both your application and OpenGL is usually restricted. To get great performance in your application, you must carefully design your application to feed data and commands to OpenGL so that the graphics hardware runs in parallel with your application. A poorly tuned application may stall either on the CPU or the GPU waiting for the other to finish processing.
When you are ready to optimize your application’s performance, Apple provides both general-purpose and OpenGL-specific profiling tools that make it easy to learn where your application spends its time.

Concurrency in OpenGL Applications Requires Additional Effort
Many Macs ship with multiple processors or multiple cores, and future hardware is expected to add more of each. Designing applications to take advantage of multiprocessing is critical. OpenGL places additional restrictions on multithreaded applications. If you intend to add concurrency to an OpenGL application, you must ensure that the application does not access the same context from two different threads at the same time.
Performance Tuning Allows Your Application to Provide an Exceptional User Experience
Once you’ve improved the performance of your OpenGL application and taken advantage of concurrency, put some of the freed processing power to work for you. Higher resolution textures, detailed models, and more complex lighting and shading algorithms can improve image quality. Full-scene antialiasing on modern graphics hardware can eliminate many of the “jaggies” common on lower resolution images.

How to Use This Document
If you have never programmed in OpenGL on the Mac, you should read this book in its entirety, starting with OpenGL on the Mac Platform. Critical Mac terminology is defined in that chapter as well as in the Glossary.
If you already have an OpenGL application running on the Mac, but have not yet updated it for OS X v10.7, read Choosing Renderer and Buffer Attributes to learn how to choose an OpenGL profile for your application.
To find out how to update an existing OpenGL app for high resolution, see Optimizing OpenGL for High Resolution.
Once you have OpenGL content in your application, read OpenGL Application Design Strategies to learn fundamental patterns for implementing high-performance OpenGL applications, and the chapters that follow to learn how to apply those patterns to specific OpenGL problems.
Important: Although this guide describes how to create rendering contexts that support OpenGL 3.2, most code examples and discussion in the rest of the book describe the earlier legacy versions of OpenGL. See Updating an Application to Support the OpenGL 3.2 Core Specification for more information on migrating your application to OpenGL 3.2.
Prerequisites
This guide assumes that you have some experience with OpenGL programming, but want to learn how to apply that knowledge to create software for the Mac. Although this guide provides advice on optimizing OpenGL code, it does not provide entry-level information on how to use the OpenGL API. If you are unfamiliar with OpenGL, you should read OpenGL on the Mac Platform to get an overview of OpenGL on the Mac platform, and then read the following OpenGL programming guide and reference documents:
- OpenGL Programming Guide, by Dave Shreiner and the Khronos OpenGL Working Group; otherwise known as 'The Red book.”
- OpenGL Shading Language, by Randi J. Rost, is an excellent guide for those who want to write programs that compute surface properties (also known as shaders).
- OpenGL Reference Pages.
Before reading this document, you should be familiar with Cocoa windows and views as introduced in Window Programming Guide and View Programming Guide.

Keep these reference documents handy as you develop your OpenGL program for OS X:
- NSOpenGLView Class Reference, NSOpenGLContext Class Reference, NSOpenGLPixelBuffer Class Reference, and NSOpenGLPixelFormat Class Reference provide a complete description of the classes and methods needed to integrate OpenGL content into a Cocoa application.
- CGL Reference describes low-level functions that can be used to create full-screen OpenGL applications.
- OpenGL Extensions Guide provides information about OpenGL extensions supported in OS X.
The OpenGL Foundation website, http://www.opengl.org, provides information on OpenGL commands, the Khronos OpenGL Working Group, logo requirements, OpenGL news, and many other topics. It's a site that you'll want to visit regularly. Among the many resources it provides, the following are important reference documents for OpenGL developers:
- OpenGL Specification provides detailed information on how an OpenGL implementation is expected to handle each OpenGL command.
- OpenGL Reference describes the main OpenGL library.
- OpenGL GLU Reference describes the OpenGL Utility Library, which contains convenience functions implemented on top of the OpenGL API.
- OpenGL GLUT Reference describes the OpenGL Utility Toolkit, a cross-platform windowing API.

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.
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.
Setting Expectations
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.
Success Stories
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.

- Northgard
- Rhinoceros 5
- Navisworks 2017
- ARCHICAD 20
- Solid Edge
- The Quake series (Quake, Quake II, Enemy Territory: Quake Wars, and more.)
OpenGL Versions
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? 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.

Predicting the Performance of an OpenGL Application
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.
