I do not have it up now, but there is a Knowledge Base Article on this at Smith Micro.

There are several different things.. one is some ATI cards force on certain features which are great for games, but no so good for 3D apps like Poser. Turning off some of these or changing to Application Control normally resolves the issue.

I would need more details to be sure, but that would be a good start... I can not recall what version of Poser you are using, that may also change the specifics.
