I went and found that Launch HN, and yeah, that rubik's cube is horrendous on my computer. They did not do as much effort as you did to make it work on low end machines. I don't have a GPU at all; your site disables the background effect but their site shows the cube anyway. Their site drags once that rubik's cube appears, and the cube itself animates at 1-2 fps. It's a very poor experience and I don't really see what the cube adds, but I do see what the cube subtracts. (Your site works fine on my computer. The effect is disabled and it's not a problem.)
