I can only agree that in face of perfomance issues, we have to consider using extra available hardware. One way or the other, they have to improve the code.
I wonder, if a faster graphic card will help. I have an aging HD 6950.
I doubt it, because I have no trouble moving around, zooming in and out even with big maps at 1900×1080 …the trouble is when we reach the XXI century an the cities begin to grow in population.
