Hi,
as of latest update to release 0.5.6 (about 1 week ago) we added to amdeneir the "bump mapping" shader. In simple words is a graphical effect which makes items look more real by manipulating the light effect on them. For example if you look at the ground in amdeneir you will see now that each small stone has a light effect and looks like it "bumps" out of the flat surface. The same has been applied to all items in amdeneir, walls, lamps, signs, chairs, ... The visual result should be a way more realistic look, and gives to PS finally something other commercial games have since long time.
The question is if the new effect is working well on your machine or not, or if it's slowing down your PC too much. We would like to extend this technique to every single level in PS, but we need a validation from the current players that's going to work.
In case you don't see any difference, go and check if you have lowered the graphical settings in pslaunch, turn those up because with some low settings you will not be able to see the difference.
If you really have time, you could reinstall a fresh 0.5.6 and compare the visuals and performances before and after the update.
Thanks.
