Catalyst 7.4???

I expect that this is a driver error, cos VSM has been present since the 6800. See http://http.download.nvidia.com/deve...hadow-Maps.pdf for details.

Furthermore VSM is highly optimized for G80. See http://forum.beyond3d.com/showthread.php?t=38165 for details.

It is somewhat worrying that, if there is nothing wrong with the ATi drivers, programmers need to optimize the code to make the performance acceptable (a factor 3 is insane).
