Beside that TTFs arent really resolution free. I tested it with different sizes but in comparison TTFs are everytime different on all resolutions. You can easily test it: write a text that starts at the left border of the screen and ends (nearly) directly on the right. Then change the resolution, try another size which fits the string so that it ends again at the right. Make snapshots. Than scale the lower resolution image to the size of the other one and make an overlay in your paint program: you will see that they are different in length/height or both.

TTFs are evil: they are not really resolution free and they are SLOW.
