As of DIANA 10.3, it is required that the Graphics Card (GPU) is compatible with OpenGL 3.2 to make use of hardware acceleration of 3D graphics. OpenGL 3.2 was released on August 3, 2009 and most graphics cards in use today support this version of OpenGL.
How to verify that your graphics card driver supports OpenGL 3.2
To verify that the drivers of the graphics card support OpenGL 3.2:
- Download and install GLView: http://www.realtech-vr.com/glview/download.php (free of charge at the time of writing).
- After installation open the GLView program
- Under the OpenGL section, click See details...
- Check that 3.2 is included in the list of Core features:
Don't forget to remove GLView when your done.
Dual graphics cards
Please note that some computers contain multiple graphics cards. This is usually due to a CPU with integrated graphics (most Intel CPUs) and the presence of a separate (‘discrete’) graphics card (e.g from NVIDIA or AMD). When using the OpenGL extension viewer, be sure to check the correct driver.
Integrated graphics provided by Intel CPUs
Although in general we do not recommend using the integrated graphics available on some Intel CPUs, Intel provides a page on its website detailing the supported OpenGL versions for these processors: https://www.intel.com/content/www/us/en/support/graphics-drivers/000005524.html
