haha no problem, I think including a hint on startup of the regular version would help in the future so everyone knows that there's a lightweight version!
so specifically, the original version uses Unity's High Definition Render Pipeline while the lightweight version uses the Universal Render Pipeline, which doesn't have as many features and is meant to work well on any platform. If you compare the two side-by-side, the difference is pretty big, especially when looking at the sky, the fog, and the areas that have lighting
