<p class=MsoPlainText><font size=3 face="Times New Roman"><span lang=EN-US
style='font-size:12.0pt'>Here I just want to tell you that if a user uses an
old driver that we don’t support querying total memory will lead to
vidmem = 0, that is unexpected, so we should have a check.<o:p></o:p></span></font></p>
<p class=MsoPlainText><font size=3 face="Times New Roman"><span lang=EN-US

<p class=MsoPlainText><font size=3 face="Times New Roman"><span lang=EN-US

ATI_meminfo can still go the fall back path.<o:p></o:p></span></font></p>
<p class=MsoPlainText><font size=3 face="Times New Roman"><span lang=EN-US
style='font-size:12.0pt'>I think the biggest benefit from using this extension
is that you don’t have to update the vidmem list for newly realeased ATI cards,
and you can get the correct amount of video memory for the same render string but
with different video memory (eg: HD4870 may have 1GB memory or only 512MB
memory)<o:p></o:p></span></font></p>
