While it’s true that offloading that task to a GPU can speed it up and make the refresh effectively invisible, that’s not at all the same thing as blaming the slow refresh on an outdated driver.
I will observe that I did not see this two-step refresh on 3.x, though. I can definitely tell that calibre 4.x’s rendering engine is first displaying the default HTML styles, then applying the ebook’s stylesheet(s) with a refresh.

Do you think it might be that deback is on 32-bit Windows instead of 64-bit Windows where it could take advantage of the 16GB of ram his system has?
