Instead it, I had the same number of fps like before turning VBO on
Steps to Reproduce:

VBOs can improve your fps. Considering how old your graphics driver are, it's likely they aren't able to properly utilize them. I would recommend you update your graphics drivers. Your second screenshot indicates that vbo is enabled, so that's not the issue.
