The next three tabs are pretty self-explanatory. The prefixes of each extension tell you which company originally created it: The “extensions” tab gives you a list of extensions supported by your driver along with capabilities and limitations of your video card. See one of my previous articles: Certain Notebook ATI Video Card Drivers Not Supporting OpenGL 2.0. However, for third-party drivers, it’s definitely possible. In fact, I don’t see any reason it would happen. For drivers written by ATI and Nvidia, this would be very unlikely. It’s possible to have “gaps” in your OpenGL support where the driver doesn’t implement all the functions of one version but does implement everything in a higher version. Whichever version you found was greatest is the actual OpenGL version installed on your machine. Look for the highest version number with “100%” support that also has “100%” marked for all versions prior to it. For each version it shows how many functions are supported by your card’s driver. The first tab shows you some system information and a list of all OpenGL versions. After this auto-detect cycle is complete, you’ll see a dialog similar to the one below: Don’t worry, this is completely normal – it will stop after about 15 seconds. When you run the program your screen may do some weird things (go blank, flash, etc.).
Not only will it give you information on what OpenGL version you’re running, it can also give you information on the generic software emulation driver. I’ve used this program forever on many different cards / configurations and it’s never failed. Start by downloading an application called GL View by Realtech VR.
Have you ever needed to check which OpenGL version you’re running? Ever need to see which OpenGL extensions are supported by your card and/or video driver? Well, look no further! This post has the answers along with how to get some very useful information about your video driver.
