do you have some numbers indicating an improvement with this change? On what hardware did you test?

I wasn't measuring performance. This patch is actually a fix, because AFAIK 2D tiling is the only mode available for MSAA surfaces. The other tiling modes hang my GPU.

AA surfaces can't use linear or 1D tiling modes. They have to be 2D. Resolve targets can use other tiling modes however.
