brief fixme

I got a chance to test Bayonetta in Window 7 and realized it's much slower in
Wine (about half the fps) than Windows, whereas I previously was
underestimating my hardware. I recall reading that such a high discrepancy
should probably be reported.

The game is already difficult to play under Wine because it it requires one of
the async read/write patches in bug 42982 to make headway. Also note the game
requires CSMT for coherent visuals.

Can this fixme cause a major performance problem?
fixme:d3d:state_zenable Unrecognized depth buffer type 0xffffffff.

The game seems unusual in that it ties all actions to vblank/vsync, if that
makes any sense. In Wine terms I guess that means it relies on this function,
though as I'm not a developer I'm likely wrong:
fixme:d3d9:d3d9_device_SetMaximumFrameLatency iface 0x1574b0, max_latency 1
stub!

Anyway, the game already requires a native d3dcompiler_43 to avoid HLSL parsing
failure, but any tips/patches/suggestions to improve performance would be much
welcomed. I tested a recent Mesa git version that has a GLSL cache but it
didn't really help. I understand that I'm already running an Intel potato, but
based on my recent Windows experience I think we could get the game to native
speed one day.

Also, I bet that all of Platinum Games' ports suffer the same engine (for
example Nier Automata), though I'm not sure.

Full fixmes attached for completeness, also tried a native xinput and d3dx9_43
with no change.
