adding two Mega of VRAM to your card is not going to increase the speed at
all, rather the number of colors that you can display at a given resolution
(tousands versus millions at 1024 x 768 or higher)
A faster video card could slightly increase the speed, but I think it's
rather the speed of the processor that causes the problems, Cellquest is
not getting slower with million events because of the video card, but
because it has to recalculate all the regions, gates and statistics each
time you change something... so you would really not gain very much with a
faster video card... and there is no "hard acceleration board" for
Cellquest like there are for Photoshop...
The best is to tell you user to make sure that he doesn't acquire
unnecessary events to his files... the second best is to make sure that you
have turned Virtual Memory OFF (means probably to add more RAM - and
allocate it to Cellquest), that's where you will get the biggest speed
increase if you didn't do it already...
Hope that helps,
Matthias
