I often see people complaining about "it's just text, why is it so slow to render", you can render a high res 3d environment faster then you can render the same screen full of text. That said, the text rendering engines of today are very optimized. So it's relative fast considering the amount of work. And humans are very sensible when it comes to text, a human can notice if one pixel has the wrong color in text, but wont notice it in a 3d scene.
