You really have to live with the reduced resolution on the text due
to DVR. The main problem which it sounds like you have solved is the
resizing of the text.

You may be able to reduce the width of the GL primitives you use as
you reduce the resolution but this really depends on your starting point.
If you have a line width of say 2.0 then your in luck, if however your
line width is any less than 1.0 then this would be of limited value
other than to properly weight the text and alpha could perform this better.
If you are using polygons then there's not much you can do to help.

You could use an additional video output channel for the hud to
avoid having to resize the HUD elements if you can afford the display
system. You can't mix the different resolution channels to one
video using the iR.

Cheers,Angus.
