The OpenGL Software Accelerator is a software rasterizer for OpenGL applications such as ArcGIS, Google Earth, Nehe, Maya, Blender, Voxler, CAD, and CAM. In some cases, the OpenGL Software Accelerator can eliminate the need to use graphics cards to deliver a good user experience with OpenGL applications.
Important: The OpenGL Software Accelerator is provided "as is" and must be tested with all applications. It might not work with some applications and is intended as a solution to try if the Windows OpenGL rasterizer does not provide adequate performance. If the OpenGL Software Accelerator works with your applications, it can be used as a way to avoid the cost of GPU hardware.
The OpenGL Software Accelerator is provided in the Support folder on the installation media, and is supported on all valid VDA platforms.
When should you try the OpenGL Software Accelerator?
- On servers without graphics processing hardware, if the performance of OpenGL applications running in virtual machines on XenServer or other hypervisors is an issue, try using OpenGL Accelerator. For some applications, the OpenGL Accelerator outperforms the Microsoft OpenGL software rasterizer that is included with Windows because the OpenGL Accelerator leverages SSE4.1 and AVX. OpenGL Accelerator also supports applications using OpenGL versions up to 2.1.
- For applications running on a workstation, first try the default version of OpenGL support provided by the workstation's graphics adapter. If the graphics card is the latest version, in most cases it will deliver the best performance. If the graphics card is an earlier version or does not delivery satisfactory performance, then try the OpenGL Software Accelerator.
- 3D OpenGL applications that are not adequately delivered using CPU-based software rasterization may benefit from OpenGL GPU hardware acceleration. This feature can be used on bare metal or virtual machines.
