<div id="intro-container"><div class="truncate"><div class="attr SYMPTOMS"><div class="attr TOPIC"><FONT SIZE=4><BR>
Does extra VRAM in the Macintosh Quadra improve speed?  For example, if I<BR>
install 2MB of VRAM in a Macintosh Quadra and use a 13-inch RGB set to 256<BR>
colors, I get 1.5MB more than what is needed to display 256 colors. Does<BR>
this improve the video performance/speed compared to 0.5MB?<BR>

  <div class="attr SUMMARY">
Having extra VRAM available on a Macintosh Quadra beyond what is required<BR>
to support a particular pixel depth doesn't give any performance increase.<BR>
<BR>
This is not true for the Macintosh Display Card 8*24 GC, where the<BR>
additional and optional DRAM space is used for off-screen data structures.<BR>
