Quick question!

My older brother is using my old laptop and when he wanted to see if a game can be played on it i sat in front of it cheked the GPU and the memory and the version of the video card was not the same as it was before.

So is there any chance the drivers arrent correct and if thats the problem wold the laptop see the GPU as it was before because before about 3 moths it was really much more powerfull?And now if the laptop sees it as a slower video card woldnt it have a much harder time runing a game?

Have you tried updating the drivers?
