My recommendation is to do a few renders and sort of prove your point. I happen to agree that the texture filtering on kinda stinks but I haven't been able to use Poser 7 on machine (it doesn't work well) so the point is mute.

Try a few renders to show that texture filtering on and render settings looks worse than the same render settings etc. It might even take more time. Time the renders, compare, post so we can see the issue etc.
