    I'm trying to minimize the VRAM usage, and since the DXTn compressor is still produces artifacts on higher mip levels, I thought of using 16-bit textures as a fallback. I'm using GL_RGBA4 and GL_RGB5 internal formats to be specific. The problem is that I don't see any difference in VRAM usage and visually the textures look the same, which suggest that they are still in RGB/RGBA. I also tried setting the TGLLOWQTEXTURES environment variable, which used to force every texture into 16-bit, but it didn't have any effect either. My question is, was the 16-bit texture support removed, or is there some bug that prevents the resampling of the texture into the requested format?
    This is just like television, only you can see much further.
