It sounds bit odd but really a software  exists which works like a real graphics card and can emulate video memory to play high detail pc games. While surfing cyber world I found a wonderful tool which works as a virtual graphics card but I did not believe on the story and decided it to test on my PC. I  unplugged my real graphics card in my Pc which was already installed and install this virtual graphics card and I find it really working. However it does not support all games but I have tested it on Alarm for Cobra Nitro.
