I think performance issues are actually not a graphics problem. I created this game on linux and I cross compiled the windows builds. I then later went to see how it was on windows and it was unusually slower compared to when I played it on linux. And my windows computer was pretty powerful, and ran other arguably more intensive games faster than this one.
I will look more into performance next game jam I do. I went with good graphics because I am good at the visuals side of game development and wanted to show that here. (I did not have the time to make models or textures, so that is why I downloaded them off the internet) I also wanted to see how good I could get Godot to look and I think that really showed off how far Godot has come within the last few years in the world of 3D graphics.
