Hello, my friend just bought a new graphics card to go along with the integrated graphics on his AMD A4-3300. He bought an AMD radeon 6450 by XFX. He says he gets reduced framerates after he installed the card. EX: 90 fps in minecraft with integrated, 40 with 6450: about 30 in All Points Bulletin with integrated, about 9 with 6450. The list goes on and on. He hasn't modified his graphics settings at all. Can you guys help?
