So running FlatOut 2 on Linux with Wine 1.1.19 I got the following error:

fixme:d3d_shader:shader_arb_generate_vshader HW VertexShader Error at position
1543: "Too many parameter variables"

It turns out it is caused by this VertexShader fragment:

   PARAM helper_const = { 2.0, -1.0, %d.0, 0.0 };
   ...
   MOV result.fogcoord, 0.0;

From what I have been told (I'm not a 3D expert), the MOV causes the driver to use a shader constant for the 0.0, thus going over the limit. We've worked around this issue by rewriting the above as:

   MOV result.fogcoord, helper_const.w;

But it has been pointed out that the driver should be able to figure this out by itself and do the optimization itself. Hence this report.

Packages:
 * From Debian Testing
 * libgl1-mesa-dri 7.0.3-7
 * linux-image-2.6.26-2-686 2.6.26-15
 * xserver-xorg-video-intel 2:2.3.2-2+lenny6.

To reproduce:
 * Go to http://www.winehq.org/announce/1.1.19 and grab Wine 1.1.19 (later versions will have the workaround I mentioned above and thus not be suitable for reproducing this issue)
 * Compile / Install it.
 * Install DirectX 9 or copy d3dx9_36.dll to ~/.wine/drive_c/windows/system32.
 * Download the FlatOut 2 Demo from:
   http://www.gamershell.com/download_16702.shtml
 * Unzip that file and chdir to that directory.
 * Then run:
   wine FlatOut2.exe

The game should crash on startup and print the above HW VertexShader error on stderr.
