I am working with a very large assembly and it is impacting the computers performance. Example: Rotating the model is choppy and slow. First thing I decided to do was go to options to reduce the image quality and change the level of detail. However, those options are grey and not selectable. The files were created by an former co-worker and was part of a pack and go. I am not familiar with pack and go.

Would my problem be due to some sort of read only option ( assuming pack and go has such security measures)?

I'll try to learn more about pack and go after posting this question.

Thanks in advance.
