If you're running below spec, (i.e. less than 12GB vRAM) you might consider using the OpenGL rop in the /out context for producing your flip books. There are controls on the rop to customize the quality. Another thing you can try with heavy geometry is to poly-reduce it or quad remesh it to a produce a lower primitive count. This reduction can help the view port. Also move your mouse over the 3D viewport and press the D-KEY. There are quality controls for the viewport under several tabs.
