Set Q3InteractiveRenderer_SetRAVETextureFilter to kQATextureFilter_Fast 
to get the old pixelated look, or (better yet) use MipMap textures with 
UseMipMapping set to false instead of PixMaps.

What you're seeing is mipmap filtering, which is actually considered 
_higher_ quality since it reduces pixel crawling and moire artifacts. 
The default filter setting (kQATextureFilter_Mid) uses bilinear 
filtered mipmaps, which have a tendency to blur as the image size is 
reduced. kQATextureFilter_Best will provide better results, but you 
will still see some blurring.

The best of both worlds can be had by using anisotropic filtering. I'm 
considering adding this to a custom Quesa build via the Set/GetProperty 
API for my own purposes, but I'll gladly share the code with anyone 
interested.
