It always runs above 30 fps when you have 3 resolution or higher and low texture resolution. It doesn't run nearly as good with high texture resolution, that issue could be fixed by posterizing the colors a bit before drawing them. If you want to know how I made it run faster: I modified the pen script (TexturedFiller) to make it draw lines when it can, instead of only drawing the screen one point at a time.
