Garrys mod menus lag

Whenever I hit Q or Tab my fps drops.
I have a Amd Six-Core fx610 processor
Amd Radeon 7450 graphics card.

Does your processor happen to have integrated GPU? If so that is whats causing the problem.

I don’t think that my processor has an integrated graphics card. If it does though how do I disable it.

I think you cant disable it Because I have integrated GPU and I havent found a way to disable it.

I checked and I do not have an integrated gpu, so any other ideas.
