Best Way to Display large feature class

I'm working with a large dataset of over 100,000 records, and my client would like to have all points displayed at the world view. Cache is not an option as the data changes constantly, and performance is a bit slow (5-6 seconds per refresh). Scale visibility is not an option as the client would like all points displayed at all times to the user.

The points overlap each other at the world view, therefore I'm wasting lots of performance there.

Is there any re-sample technique that I could use to just display the points that would be seen and not waste performance on the ones buried underneath other points.

Thanks in advance,
