You "can" use higher resolution textures. You do not "have" to.

To stay DS compatible most provided textures do not go over 4096x4096.

And if you use the "quality" or "crisp" option the texture caching option in the recent Poser versions reduces memory usage.

If you set the texture filtering to "none", you loose texture caching and PC/MAC slow down.
Filtering is the lower option box in the textures window.

General prefernces => Goto => Render Tab => Texture caching => Let it run in background.
