This will be a challenge for us as we move forward with development of the
OSG tree. How much old hardware should we support, and how far back should
we go?
I think it makes sense (at a minimum) to make sure these features that
require newer hardware can be turned off so that people with older hardware
can still run the basic code and see the base scene.
In some cases it may make sense to have a backup scheme available so older
hardware can see something, even if it's slower or less detailed. (For
instance, we have a couple runway light schemes floating around.)
But at some point we do need to decide where to draw the line. For instance
we already have abandoned support for 4Mb Voodoo1 cards and Glide. But
those were pretty hot when the FlightGear project first was launched. I
remember running glide in a window on an 8mb voodoo2 ... ahh those were the
days ... I may still have that card in a box somewhere ... saving it for my
grand kids to play with. :-)
We do want to make reasonable and informed decisions here, so it's worth
discussing a bit. We don't want to abandon too many people, but at the same
time we want to be able to push forward with new features and new graphics
effects ...

At some point, I'm buying a new graphics card or new laptop if I have to ...
and as much as I hate to admit it, over the years, flight simulators and
possibly other games have often been my primary hardware upgrade motivation.
