ParaVIew binaries don't ship with any OpenGL implementation. It uses whatever OpenGL drivers setup on the machine it's being run. So long as your environment is setup properly, ParaView will indeed use the hardware available. However, not all rendering techniques in ParaView will use the graphics card -- as Armin alluded to. Your dataset seems like small enough that volume rendering should be pretty instantaneous. What is the "Volume Rendering Mode" on the Properties panel set to? It should be "Smart" by default -- that will ensure that the graphics card is used, if possible.
