Hi J-S, I was on vactions. But if you are still interested I did the test you wanted. I have added ThreadingHandler to shadow example. Pressing m does not crash the program but freezes shadow map. Shadow map is no longer refreshed. I did the same quick test with prerender example and results are similar. So the issue is wider and might be related to RTT camera usage. I also did prerender test with -fb (render to frame buffer switch) and everyting worked correctly.
My machine is Athlon 64 X2, GeForce 7800 GTX, Windows XP (drivers ver 169.44). Tested on Single Monitor and Dual Monitor with all possible multithreading optimization choices from NVidia control panel. None of the NVidia options seemed to fix the results.
