I first discovered this "secret tweak" in July 2014. No one else seems to have written about it on the Web, so I offer it to my friends here. Many of those friends have tried it since, mostly with great success. So I have formalized it and written the instructions on my OneDrive. (Click on my signature banner to go there.)
It's very very simple, with few downsides, and the frame-rate improvements can range from marginal to spectacular. Most people seem to find it worthwhile keeping in. Let me know what you think!
