it is a bit slow I think, the Nova logo is slow.
the framerate is lagging with the cube as well. its known that tabor hardware has an incompatible fpu and therefore performance issues. daytona already reported that it shows with warp3d nova particularly, because the lib is ridden with fpu calls that interfere with spe calls even with tabor natively compiled software.
cant tell how performant os4 hardware is in this respect altogether, but given low polygon count in these demos its not up to much.
