Hi J-S, I did the test at home. I have really crappy machine there. WinXP Athlon XP 1700 and AGP GeForce 6200 (drivers ver 169.28). And guess what ? It works ;-). Since its single core machine and agp it still does not bring us closer to answering the question whether OSG or Driver fails, but at least there is one case when it works ;-)
Since this machine is single core osgshadow starts with SingleThreaded mode. But I did aditional test - I forced it to start with CullDrawThreadPerContext. And in this case problem appears again. After pressing 'm' couple times shadow map freezes. So reasumming when is start in SingleThreaded mode it works. When it starts in CullDrawThreadPerContext it stops working. Interesting isn't it ? Had no more time to continue experiments maybe will do more on weekend. It would be interesting if somebodey with single core machine and decent PCI express GeForce did the test...
