This wasn't the case in my experience. When my cousin was playing the game, it seemed to be a lot faster. For example, before the character selection screen, when it's zooming in on the top of that wireframe sphere thingy, the framerate would drop drastically on 0.1. On 0.2, that's not the case. The framerate drops slightly (somewhat noticable), but not as bad, and that's the ONLY slowdown I saw in the game. Everything else was nearly perfect, and the blockiness is now gone, so that's another plus.
