--- Comment #1 from Francisco Casas  ---
The game tries to compile vs_1_1 shaders that use a very large uniform array.

Simplifying, something like this:

int i;
const float4x4 mats[100];

float4 main() : POSITION
{
    return mul(mats[i], float4(1, 2, 3, 4));
}

Our current approach for loading arrays consists in basically loading all array
elements. This is what pixel shaders do since they don't allow relative
addressing.

But vertex shaders as soon as vs_1_1 have the a0 register which allow relative
addressing.

Without relative addressing support, we are compiling huge shaders (in both
instructions and temp registers) that take a long time to compile and to run
(if they can even run), which results in the black screen.

I will get to work on SM1 vertex shader relative addressing.
