I upgraded it yesterday night from windows 8.1, but i could not test it.

So today I got home and went testing it, but my games weren't running like before. So I checked my drivers and they are all up-to-date.

After seeing the drivers I used the command "dxdiag" and I saw that I was using only 1gb of the 8gb I have.

I tried changing it in "msconfig" but it didn't worked.
