[osg-users] Amount of texture memory used

[Gordon Tomlinson]

With OpenGL and OSG the short answer is no there is no way to do this,
Opengl itself does not provide any feed back, one reason being when its card
memory is exhausts it typically pages to system memory ( not always but in
most cases )
 
Also remember it is not texture memory really it is simply memory on the
card that is uses yes for texture but also for your verts, colors, normal's,
shaders, desktop, buffer etc etc so any method you use to track usage has to
take into account of all the things that eat the cards memory and it will
only be an estimate...

Subject: [osg-users] Amount of texture memory used


Hello All,
 
Is there a way to find out how much texture memory is being used?  We are
finding that keeping texture memory in check is critical to the performance
of our game, depending of course on how much memory the card has.  
 
Thanks
