How can I use the GPU related Photoshop CS6 features?
Can't use the "Lighting effects" in Photoshop CS6 (WIndows XP/32), probably because "Advanced" drawing mode greyed out. CS6's System Info reports "OpenGL Allow Advanced Mode: False." and "Video Card Renderer: GeForce GT 220/PCIe/SSE2". I installed the latest NVDIA driver (May 2012) for the GT220 video card.
