First let's look at Help > System Info in Photoshop.
What does it give for GPU memory?
For example, I see this on my Macbook:
glgpu[0].GLMemoryMB=256
glgpu[0].GLName="NVIDIA GeForce 9400M OpenGL Engine"
glgpu[0].GLVendor="NVIDIA Corporation"
No matter the driver, 256 MB does not meet the 3D requirements.
