How do I fix a video card that prevents me from playing a game that I purchased?

Maybe your video isn't good enough for your game. You should get a really good one, it's worth it.

Please find out about the pixel shreader model that your card supports. This is something related to Microsoft Direct X 9.C its got three variations I,II,III. The Third one which is the latest most of the new age games are gonna be designed based on those models. This is one of the primary reason why a lot of old computers are unable to run the new games that were released this year, If you go for a card like N vidia G Force 6500 which is a very wallet friendly card its ready for all the games that are available in market its a DDR2 card with 256 graphic RAM & It supports shreader model III. For more information on the issue I would like to know the name of the AGP or PCI e card that your using or the name & model of your computer if its a branded one.

get a new vidoecard like a $5000 one its worth it
