Re: Multisample(FSAA) maximum samples...



From: Brad Anderson <email@hidden>
Subject: Multisample(FSAA) maximum samples...

When a graphics card supports multisampling, It is easy enough to
implement the multisample environment.  Nearly all cards that can do
multisample support the 2x and 4x modes.  There are 6x 8x and 16x
modes.  My graphics card supports these modes.  It make the scenes look
BEAUTIFUL.

Now, When my program runs on a machine that only supports a maximum or
4x, how can the program figure out that that is the highest supported
multisampling?

Figuring out if multisample is available is easy, getting the max
multisample supported is REALLY hard!  I have scoured the web and found
nothing on this topic.  I don't want to code the max FSAA/multisample
for each card and have to rely on that table for telling the user what
their graphics card can support.  I should be able to figure it out
from some function, string, query, etc what the value is.


I have the exact same question!

How to establish what the multisampling limits are without resorting to inferences based on the renderer string or something.
