Textures gets messed up depending how closed you are

Interestingly, the screenshot with missing polys seems to be with the software renderer.

Is this (gcc) compilation issue? A debug build should determine if it's an optimisation issue.

Ok, i tested it with Directx 9...and it seems the problem only goes with opengl...software render dont has the problem either.
so its only opengl...but dissabling mipmap will cure the texture behavior.

Check Your texture, probably is NPOT (rescale it 2^n on width and height, eg 256x256, 1024x512 etc. POT textures should work ok)

Hmmm when its NPOT it works fine, i think that was my problem..maybe

What is the size of your texture exactly when it works fine?

That is a POT (power-of-two) texture. It is not a NPOT (non-power-of-two) texture. I realize that english is probably not your first language, so I just wanted to clarify that for you.

You should always use POT textures (256x256, 128x1024 etc...) and update graphic card drivers (to Catalyst 9.3). With C9.3 NPOT should work OK, but as I said it isn't recommended.

One thing we could check also is the ZFAR of the view frustum. The second picture looked like it was being clipped.
