- when I selected highest shader quality for Model shader, sim crashed, other shaders at max setting was OK
Generally I find it difficult to come up with a scenario (short of a buggy graphics driver or out of memory) in which a shader can crash the main application - because they're not really talking overly much to each other - the shader runs on the graphics card, the main application on the CPU. I can't rule out that there may be a way to do that anyway, but I wouldn't even know where to look for a debug solution, because what the shader is actually doing when being compiled is completely dependent on the graphics driver...
