Shadows are broken (seem to be fragmented) in the eXperience 112 game.

Terminal output doesn't reveal too much:
...
fixme:d3d9:Direct3DShaderValidatorCreate9 stub
fixme:d3d:wined3d_buffer_preload Too many declaration changes or converting
dynamic buffer, stopping converting
fixme:d3d:state_zfunc D3DCMP_NOTEQUAL and D3DCMP_EQUAL do not work correctly
yet.
...
fixme:d3d:resource_check_usage Unhandled usage flags 0x8
...

Shadows appeared correctly in 1.3.22. The result of the regression test:

    wined3d: Give GL_ARB_map_buffer_range another try.

    Nvidia's 270.xx.yy driver series fix the glMapBuffer alignment issues that
caused major
    performance problems. If the user is using an older driver we now drop the
VBO instead of using
    doublebuffered loading, which means that we fall back to the current
behavior(no dynamic VBO) as
    needed. Dynamic VBOs are needed on Nvidia drivers for
GL_ARB_instanced_arrays.

Other bugs related to this commit: bug #27534, bug #27600, bug #27959.
This might be a dupe of any of those.

As for performance issues due to this commit, I don't see major performance
degradation, just because this game always performed badly on my system, when
one or more cameras were activated in the game (5-6 fps @1024x768 resolution).

Steps to reproduce the problem in the demo:
Install...launch...new game..skip the intro video...the problem can be observed
right in the opening sequences.

Nvidia 250 / driver 280.13
