I rewrote the shadercode, which allows me now to do an a lot better looking blur with better performence

Now that looks awsome!

Seems that you got rid of the ugly stripes with this. Great.

Here is another screenshot...

Looking good, as always

Any info on what you are using? I guess PSSM and some nifty blurring? Did you try out the ESM thingy?

At the moment it is just some kind of PSSM and PCF.
It looks also quite well in motion and is very light/shadow bleeding free
The only disadvantage at the moment is the speed or to be more precise, there are just sometimes some moments where the ref time goes up a lot, while most of the time it runs quite okay...
I will may look into ESM somewhen later, but for now, this seems to be the most stable way to blur the shadows.

The last screenshot looks great!!

awesome!
Cant wait to see the final version ^^
nice job slin

For now, I disabled the blur (to be honest, it is still calculated, just not visible...), added a fourth depthmap and did some other minor changes.
This is what it looks like:


There are still some artifacts, but most should disappear after some blurring and the rest gets hopefully hidden by the shading.
I also uploaded a published version of the shadows and would like to get some feedback on strange behaviour like shadows nearly everywhere and something like that. If you encounter any other problems than a bad fps I would like you to post a screenshot of the problem and some information on what graphics card you are using. Thanks.

For some reasons the camera starts to fly lightning fast to the front when I press "0". Could you please fix that in your published version and can you please add a toggle key for the blur? I'm curious how it looks like!
