Thanks for the comprehensive information on this subject.

I will create radio buttons in my program for the User to select from a
range of buffer sizes. What would be the lowest and highest value I
would want to use for the first and last button, and what increments do
you think these buttons should be in?

My goal is to offer the most precise control over double buffering so
they can get the best performance for their particular setup and usage.

Many thanks for this great software that keeps us motivated to expand.
