Tree, it's only useful if you are running an Ati GPU because the logo playing "confuses" the drivers and "locks" the GPU into low performance mode running at lower clock speeds.
You have an nVidia so you don't get this issue and that's why you don't see any performance difference.
You can still keep it disabled though to save time starting up the sim. Since it can't be skipped and it forces you to sit through an extra couple of seconds before the sim loads, renaming/deleting it will land you straight on the epilepsy warning screen which can be skipped by pressing Esc (maybe other keys too) twice
