glmark2 Score: 1967
=======================================================
I do not know the score indicates. I've seen some posted that are much higher. Is the score relative to the individual GPU?
Would a perfectly good low range GPU have a lower score than perfectly good super dooper GPU?

Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.

My understanding of this test is that if the numbers do not go down very much, that is good. How long should this test be run?
