Hi Adrian, i see i will have a hard work to fix pssm in multi thread env. Well, we have to start testing the pssm algorithm against SingleThread, if it work without any artefakts, we can start with the multi threaded env. thanks for testing, helping, and ... good job done wojtek. As far as

Hi Guys, CullDrawThreadPerContext is also OK. My hypothesis is that Cull Traversal overlaps with Draw Traversal. So it would be classical race condition - various scenes are rendered with different timings so condition may not be obvious. Maybe thats the reason case -2 works ? Maybe setting D

Hi Adrian, Please check out and test, Ok, I'll test here and get back to you. Thanks for working on this to get the last issues worked out, as PSSM is definitely the technique we want to move towards in the near future. NVidia, ATI should work without choosing right plattform That's exc
