Ok. This is the second time the wiki entry I added for improved performance has been questioned. As it was made for Pre-710 release improvement on MythTV performance, and is no longer valid, for the current release, other than perhaps giving some insight on how to get your Nvidia settings to stick on a reboot, I am removing this wiki page.
It in fact did at one time resolve an issue we had with the betas of 710, it no longer has any practical purpose, so I will try to remove it, if not, could the administrator please remove it.
My apologies, seth, I didn't mean to question you.... I was just concerned about what would be taken out of that article. No meaningful discussion has occurred on the subject, so I haven't even considered removing/modifying the article (now I see I couldn't have anyway!) The information you provided was accurate on how to perform the process, and potentially it would be helpful under some circumstances... given no one else seemed to feel strongly about it, I wasn't prepared to remove it myself.
