User manual for adjusting your saw here.
When you set it up, make sure you check for square to the table, square to the fence, and check square for toe-in or at a 45 deg. angle across the blade from the corner where fence meets table, like you would check a radial arm saw. (hold a framing square with one leg against line of fence/table and other leg against blade and inclined 45 to both table and fence. Make sure all three are dead square.
I never found any way to compensate for the play in the blade itself. It seems like the manufacturing tolerances are a little too loose.
You may need a heavier plated blade. You may simply need a different saw. Those Dewalts are great workhorses, and I love the design, but it's my experience that when you're trying to miter hardwoods of any substantial size there's a little bit of drift in the cut as the blade comes through the wood.
You can try cutting at a slower rate.
I've found that makitas are a little more solid through the cut, though I don't like the general ergonomics as much...
Kind of a pain, isn't it?
Well, good luck.
