Textures scaling bugs
Is it possible to somehow fix the problem when using textures in higher resolution, bugs appear (decals become much larger than necessary or problems with UV)? In Xash 3D it seems that they managed to fix it, it would be cool to see it in the vanilla version too, if possible. And it would be cool to increase the resolution limit for skyboxes (the original "understands" only 256x256)

Unless the fix is trivial enough to be implemented with a couple hooks at most, probably not.

This seems a bit more doable. I can see the engine passing 256 for what is presumably the width and height to qglTexImage2D despite reading the width and height from the BMP (but not the TGA, curiously). Although, I'm not sure how useful fixing this would be considering that no mod would be shipping non-standard skyboxes unless they're intended for xash.
