The DX9 vs DX11 performance hit
The DX9 vs DX11 performance hit
Here we peek at performance scaling in-between DirectX 9 and DirectX 11.
Now for this test we used the Radeon HD 6870 X2 card we reviewed last week. That gives the game a lot of GPU power. We could see a single GPU mid-range card take a bigger hit then this card as it doesn't have to fight off little bottlenecks here and there, but its a good indicator of the performance hit.
So above the performance scaling in-between DX9 and DX11. Both selections run with 4xAA enabled and are setup in Ultra performance mode. We assume that on average DX11 mode takes a 10% maybe 15% performance hit, and that's not a bad tradeoff really.
