           Summary: Lara Croft and the guardian of light have very low
                    performance without neckloop even at lowest resolution
           Product: Wine

          Hardware: x86-64

plain wine console output at 640x480 with lowest settings and
+fps,+tid,+timestamp

Lara Croft and the guardian of light runs well at 60 fps (and at 100 and more
fps if vsync is disabled) on the menu, but during the game it has a performance
drop of about 14 fps even at the lowest resolution and with the settings as low
as possible.

CPU usage is around 20-35% for the game for a maximium total of approx 60%
consider steam and wineserver, and 5-10% max GPU load measured at 640x480
resolution and lowest possible graphics settings and approx 300mb of RAM so
it's do not appear as an hardware bottleneck.

I tried some old versions (about 3.x) of wine to exclude other regressions
(like bug 46942) and the performance on all tested versions are identical.

I also tried wine-staging with pba patches and all mentioned wine version with
unsupported dxvk and dgvoodo2 and performance are identical also on it.

So it seems that the problem is not in d3d* and something others goes wrong in
Wine, but I am not able to define exactly what.
