The code wasn't used, and generally low level hooks should be avoided
since they affect the responsiveness of all applications. On Windows 7
and later, the hooks may also be silently removed if they timeout, which
could be possible under heavy load.
The close hacks don't work with PCSX2 - the WM_CLOSE message can't
actually be triggered for the rendering window. The hacks were also
designed as a workaround for some PSX emulator close window bugs, which
don't affect us.
Enable it to ensure correct rendering (FMV)
Disable it to reduce GPU/memory requirement
Option will likely be removed when the perf impact will be reduced.
It's more portable.
Use _mm_shuffle_epi32 instead of _mm_movehl_ps - I think it avoids
data bypass delays going from integer to float domains on older
processors, and Agner's tables indicate that the instruction has the
same latency and occasionally has higher throughput (depending on cpu).
And switch the _mm_xor_si128 and _mm_unpacklo_epi8 around so the same
constant can be used for both C bias and alpha.
* Fast accurate DATE is always enabled, it was faster than standard DATE
* The less fast version is always enabled too. It is likely barely used
so perf impact will be small on few game that could hit this path.
Nice rendering has a higher priority
* The "slow" path will depends on the date option.
Note normally it isn't too slow (-10%) if GL_ARB_shader_image_load_store
is supported but AMD crimson is an epic fail.
Fixes games like Time Crisis 2/3, which use two half-width display
rectangles placed side by side in split screen mode by using different
DISPLAY.DX values.
Issue1: Depth buffer is wrongly invalidated only the first page is detected.
Issue2: First page seems to be partially written. Could be a GSdx transfer bug.
Anyway, invalidation only support a page granularity.
So here a quick workaround that will clear depth buffer in case of very small partial write.
Might worth to check regression on nocturne/digital saga
Also make the build noisier to prevent some build failures when download
speeds are slow from whatever repository.
Note: The 64-bit devel build currently doesn't benefit from ccache for
whatever reason.
