the findvis command ( available on Irix 6.2 + ) will show the visuals available
on a machine ( pre 6.2 use xdpyinfo ). So use /usr/gfx/gfxinfo to show the
managed area of the screen, then findvis ( if you log in remotely remeber to
set the DISPLAY env var to the machine of interest ). On Max Impact you'll get
something like:
holodeck 4% /usr/gfx/gfxinfo
Graphics board 0 is "IMPACT" graphics.

He should be careful not to ask for 'hard coded' visual numbers in his app
though as they may change, just check the visual he got with glGet() and look
at the GL_RED_BITS, if that's 12 then there's your answer. To check his app
without changing code then use xwininfo -tree, click in the app window, then
use xwininfo -id on a specific window id to see the attributes of that window.
The gfx QnA in the January '97 Pipeline includes a discussion of visual
selection.
Bear in mind that the texture resolution is a different issue, on Impact the
following are the supported texture formats on different TRAM configurations.
BITS/COMPONENT 4 4 4 4 8 8 8 8 12 12 12 12
