When objects with opacity < 1 are involved, ParaView uses depth-peeling to ensure that the primitives are rendered in correct order. Depth peeling is a multipass rendering technique which uses frame buffers etc. and hence is slower than rendering without depth peeling at all. To verify that it's depth peeling that's slowing things down, go to "Edit|settings" and in the "Render View" options, uncheck Enable Depth Peeling.
