John D: I am using Mozilla Firebird v 0.6.
Big D: I also tend to belive that this is just an rendering, because the amount of detail that we see cannot be run on the q3 engine, but, after taking a look at how the water looks, and at the pixel shaders used when shots are firered in the water, i ask myself, if there cand be pixel shaders for bulet-water impact, why can't there be one to simulate self shadowing.
Anyway, i really want to know where is this image taken from... it just looks too damn good !!!
