There are four main classes of GPU's depending on who makes them
1. Find out who makes your GPU
2. Find out the specific card, you can run the process Markus outlined in his first post or ask for help on this forum.
3. Find out what operating system you are using and if you have a 32 bit or 64 bit operating system. Again you can get this from the diagnostic tool Markus linked or ask for help.
4. Use the following links to update your video card drivers. I recommend doing this every 1-2 months. All of these companies regularly update their video card software and it helps fix issues and improve performance when gaming.
If you have an Nvidia card use this link
Drivers - Download NVIDIA Drivers
If you have an ATI Radeon OR AMD integrated GPU then use the following link
Download Drivers
If you have an Intel integrated GPU then use the following link

Markus, if you find this helpful, feel free to add it to your opening post.
I am assuming this would also help Mac users since TMK Macs use these four classes of GPU as well.
Probably the same for Linux. If I am wrong, someone please correct me so I can correct the information.
