This really puts a damper on my excitement for the Nexus 5 (or whatever it will be called). I hear that it will be running an Adreno GPU. On the other hand, I guess it is going to be rough no matter what option you pick in the mobile world.
(just to be clear, I'm just saying that the mobile space doesn't have to be horrible, so the adreno doesn't really have that as an excuse).
