Hi Wojciech , Thanks for your reply.
I was browsing the forums a little bit more carefully and I saw you suggestion reading links from nvidia and so on. I went on there and for a few days I need reading there and reading of the real time rendering books. Indeed PSSM is the best optimal method. But I can not get it to work under shaders for some reason. Only works in fixed function pipeline. So I am sticking with Lispm until I get PSSM working with my shaders. For flickering they seem to decrease or stop when I make the far distance a little smaller. But haven't tested that properly yet to see if it fixes the flickering or not. For artifacts I preformed the PCF and I got some amazing results. no more visible artifacts (still some minor artifacts here and there but very acceptable). But I used Gaussian blur for the ground because sometimes the PCF can be an overkill for the ground. Blur for ground and PCF for models seem to be the best methods to hide most of the artifacts and soften the edges of my shadows. Any help on getting PSSM working using shaders will be appreciated. Thank you!
