And I hope you'll understand why I don't feel it's necessary to provide links for something I didn't say. While it's okay to question or disagree with something, practicing polemics for its own sake is quite often not beneficial to anyone. I asked John for links because he made quite a few claims which asked for substantiation or, at minimum, more investigation. I don't know why you would object to that completely valid request, but at the same time am not asking for a response on that point... or, indeed, anything in this post. Instead, I'd only suggest that we all consider, prior to posting, whether a disagreement or other statement is beneficial to the list as a whole and relevant to the current thread. Finally, as it seems you may not be aware, it would show consideration for others if you wouldn't top-post. So, just a suggestion. > > On Sun, Oct 5, 2014 at 5:57 AM, ken <gebser at mousecar.com> wrote: > >> On 10/05/2014 04:58 AM ken wrote: >>> On 10/05/2014 04:02 AM John R Pierce wrote: >>>> On 10/5/2014 12:48 AM, ken wrote: >>>>> >>>>> I sincerely *hope* that it isn't some kind of trend that >>>>> video cards are using shared memory instead of dedicated >>>>> memory on the card itself.
