HTC Desire :: Snapdragons Good For Games?

Don't get me wrong, I didn't get a desire for gaming (i think we have got a long way to go before Android is a viable gaming platform), but I am sometimes surprised by the Desire's inability to run some games properly. Snapdragon processors seem very good at number crunching, but struggle with graphics. Look at the Quake 2 comparison of the Galaxy S and the Desire. of course, the Galaxy S is going to win, but I was surprised just how bad the Desire game out. can't have been more than 3-5 frames per second. I have seen this in other areas to, like the recent Sims 3 conversion for Snapdragon processors. Again, once things get a bit busy on the screen, the snapdragon simply starts to drop a ton of frames. So, are we seeing devs not optimising games for snapdragon processors? Or are snapdragons simply no good for games? That said, raging thunder 2 runs quite well. Like I said, this is more out of interest than anything else. Really like the Desire and never intended to do much 3d gaming on it, but some early results have been a little disappointing.
