At the grazing angles the undersampling is going to be very extreme, and even 16 samples won't be enough. So you'll get either aliasing artifacts, or blurring due to the hardware using a lower-resolution mip level. You'll also get issues from the hardware using various approximations and "optimizations". Usually you can turn these off in the driver control panel. Typically they'll have some sort of "quality" slider that you can turn up to get better filtering results at the cost of additional performance.

MJP is right and also It looks great by the way! There's different sampler states you can also use if you want a texture rendered differently like point sampling amongst others. What are your settings for your device upon initialization? My sample count is 8 and sample quality is 32 getting the 8x MSAA and I'm hooking it where the player can change the settings inside the options menu.. However, your texture suppose to look like that do to the furtherest edge away from the camera gets blurred. Let me show you an example of mine from my editor.

If you can see the checkboard texture is blurred at the end? It's using the same sampler like yours but the texture isn't streamed like yours. So, you're looks normal like it should be.

Awesome job getting it solved!
