comment XNA texture stretching at extreme coordinates
I'm still a little curious too, but have run out of ways to test it. Every example of this issue I've seen online has been attributed to floating point precision, though none give a great explanation of why. I can play with spritebatch settings all day but I suspect, if an answer can be found, it's going to have to be by someone with lower-level GPU knowledge.

Added non-square non-power of two test results.

comment XNA texture stretching at extreme coordinates
@DavidGouveia Ah, I was beginning to think it must have something to do with the internals (either of XNA or the GPU) doing calculations in floats and losing precision. I was just hesitant to settle on that because I wouldn't have expected that to stretch the texture like it does. Of course, I'm not sure what I would have expected it to do...

Just ran a test with a 25x33 texture and the stretch point is now around (-13,107,000, 17,301,000). So while it appears to be related to the aspect ratio of the texture, it isn't directly related to the texture's actual size.

In retrospect, it's recurrence at 2^n is likely because my texture sizes are 2^n. Will test momentarily.

Updated with data for 1024x1024 texture size, as well as noting additional stretching points at coordinates 16,777,216*2^n. Also, I mistakenly used a 64x66 texture for my previous test, using 64x64 indicated the same stretching points all other square textures show.
