Before this patch, when recording Progressive (frame) mode, it recorded all
the frames correctly but set the clip's fps property to 25/29.97, so when
played back it played at half the speed (but was fine when played at double speed).
This patch does not affect the number of frames recorded per second, but rather
only sets the resulting clip fps property to the correct one (double than before).
Also fixes a bug that in a non-managed window in progressive mode, the title
displayed "200%" speed when it should have displayed 100% speed.
Fixes#832
upscale_multiplier function values have been changed to allocate native resolution and also move custom resolution to 9.
Remove the old native checkbox value and include Native in the combo box.
Internal GSDX functions have also been updated with this new update to the upscale_multiplier variable.
* Greatly reduce the number of clut read (factor 10x)
* Avoid to get wrong TEXA texture in the cache.
* Fix "jump depends on uninitialized variable" Valgrind warning.
Fix#748
I try my best to avoid any breakage of DX but please test it too.
* add lengthly comment to explain the format
* Likely reduce the number of shader permutation
* Avoid slow AEM (on GPU)
Expect regressions because TC needs some fixes
v2: fix palette mode
CID 146833 (#2-1 of 2): Division or modulo by zero (DIVIDE_BY_ZERO)
divide_by_zero: In expression this->m_width / this->m_upscale_multiplier, division by expression this->m_upscale_multiplier which may be zero has undefined behavior.
CID 146835 (#1 of 1): Division or modulo by float zero (DIVIDE_BY_ZERO)
50. divide_by_zero: In expression (float)(end - start) / (float)frame_number, division by expression frame_number which may be zero has undefined behavior
Add 2 new shaders:
* ps_main12: cast a 16 bit depth to a RGB5A1 color
* ps_main16: cast a a RGB5A1 color to a 16 bit depth
Shader might be used in future commit as it seems Silent Hill uses this
kind of format.
Fix tab/indentation too
Add tooltips to Windows GUI. Fixes#578.
Rearrange Window GSdx GUI a bit.
Reformat tooltip descriptions to be both Linux and Windows (un)friendly.
Add new tooltip descriptions.
For Linux and Windows, add tooltip descriptions for AF, AA1, extra
rendering threads, Enable Shade Boost, FX Shader/External Shader, FXAA.
For Windows, also add Alpha Correction and Logarithmic Z tooltips.
For Linux, add software mipmap tooltip.
Thanks to tsunami2311, ssakash, gregory38 and whoever did the wiki for
helping with descriptions.
The hack description box messages were replaced by tooltips on Windows,
so there is no need for the first line in the description to refer to
the hack anymore.
3-state checkboxes were also converted to comboboxes, so remove any
references to checkbox states.
Reformat the descriptions so it looks okay on both Windows and Linux.
Could be better, but I'm out of ideas.
Also fix a few typos and missing punctuation.
Changes the three-state checkboxes to comboboxes.
Removes the hack description box.
Hides Alpha and Alpha Stencil when OpenGL is selected.
Rearranges the hacks dialog.
This moves the hardware, non-renderer dependent options to the top and
makes the renderer options visible only when it affects the current
renderer.
The texture filtering checkbox has been changed to a combobox and now
uses the same description as Linux does.
Also changes the Title to GSdx Settings.
The purpose is to avoid issue on MS-Intel driver without
a dedicated hack in the compilation.
Code doesn't use it so I suspect others implement to discard the
statement.
The CRC hack option is always used regardless of whether the HW Hack
checkbox is ticked. Move it to the main gsdx dialog and make it use the
same descriptions that are used in Linux.
And fix the accurate_blend_unit whitespace formatting.
according to some of the internal functions in GSDevice files, Anisotropic Filtering is only done when paltex is disabled. do the same on the GUI for user awareness.
Removes the checkbox of Anisotropic filtering from the GSDX plugin settings, the checkbox was usually used to enable & disable the AF which is not necessary since there is an option in the drop down list for disabling AF.
the internal function value of "AnisotropicFiltering" has been replaced with "MaxAnisotropy" for detection.
the detection uses the function getconfig("MaxAnisotropy", value) where value 0 means disabled and value is the default value when no value is set in the INI file.

Apparently lintian checks grammar too (most common ones).
The Wild Arms Offset hack can only be on or off. There is no third
state. Convert the three-state checkbox into a two-state checkbox, fix
the description and remove a leftover.
Intially GSBlendStateOGL was an alias of the m_blendMapD3D9 array
The object was replaced by an index in the array. Save 2k of memory duplication.
And too much useless code.
v2: push/pop blending state in DATE stuff
v3: remove m_state which is useless now
I used to disable the RT but it doesn't work well with 50cents. It seems
texture writes weren't propagated correctly to the depth buffer. Besides
the game write an alpha value whereas depth is 24 bits only...
The purpose is to emulate correctly destination alpha factor
An alpha channel of 128 is 1.0 in the GS but only ~0.5 in the GPU
I think few draw call use destination alpha so impact on perf must remains small.
Actually it can partially be done with GL_ARB_shader_image_load_store
extension. However all drivers that support shader_image have
texture barrier too.
The idea is to use a floating texture to accumulate the data and
then do a final postprocessing pass to apply the modulo
v2:
* use bounding box to
* fix vertex corruption issue
* use negative number in shader which allow to use half float (+12
fps@4x)
Previous CopyRect function does a memcopy without conversion.
This function will allow to use different format for input/output. Just a
possibility for the future
Basically the code does the alpha multiplication in the shader therefore
the blend unit only does a pure addition. This way the multiplication is
accurate and accurate_blending doesn't requires a costly barrier.
This code also avoid variable duplication to make the code more separated.
Hopefully blending can be done in a separated function
It is preliminary work to support fast color clipping with HDR
v2: fix assertion compilation failure
v3: fix regression in not accurate mode
v3: Cs * As/Af is not an accumulation
Those cases don't need the Cd addition and were already optimized anyway
Fix a regression on GoW2
Do DATE algo selection before blending. This way we can detect bad
interaction.
Regroup all blending/colclip in a single block. Avoid to check abe &&
rt multiple times.
v2: only enable sw blending when abe is true
The updated medium level will run for all sprites. It helps sotc blooming effect and it remains
fast enough to be enabled by default (at least on 3D games)
The new high level will run for all sprites + color clipping
The idea is that sprites are often use for post-processing effect (ofc except 2D games)
Most of the time post-processing supports SW blending with a small speed penality. SW
blending is more accurate so it is better to use it.
Sourceforge was dead for more than a week therefore add the license
information. I could not find the original TGM source (dead link) so I'm not
even sure if this still applies or if the glsl was totally rewritten. None
of the glsl files have a copyright header so it's hard to tell.
Gain: 1% at 4x on SotC (it partially compensates recent additions)
When the color is constant and equal to 128, the MODULATE mode is
equivalent to the DECAL mode. It saves 5 instructions on the FS.
Accurate options do a better jobs. Technically it can still
be useful for old gpu/driver that doesn't support the GL4.5 extension.
On Windows, you can still rely on Dx
On linux, free driver support it (except Intel)
It fixes the bad light on Silent Hill with the SW renderer.
Full story
if Q is NaN, m_vt.m_eq.q becomes wrongly true
/Q will wrongly be optimized in the "Vertex Shader" of the SW
Note: Add an assert for the STQ handler
Code path is quite hot so no need to add extra check for nothing
GS uses integer value and does integer operation too.
This commit trunc the sampled texture, the interpoled fragment color
and the product of the 2.
It impacts negatively the perf of about 3/4% (GPU) but it fixes rendering on
suikoden and potentially some others games too.
Code was completey bitrotten
Code was a partial test (and yet 500 lines already)
Shader is more and more complex and multithreading support greatly
reduce the cost of shader switch
Nvidia allows to get the ASM of the shader of the compiled shader. It is useful
to check the performance.
It also allow me to compile most of shader code path for QA
Dump is enabled in linux replayer + debug_glsl_shader = 2
Code is not yet enabled because it requires extensive test
The idea is to replace point by a 1 pixels sprite with the help of
a geometry shader. In 4x, point will be replaced by a 4x4 sprite.
Partially invalidate RT when there is a write in the middle of it (actually 2 pages below)
Code is not yet enabled because
1/ I want to stabilize latest update
2/ not sure of the impact of the code
3/ maybe it need a more generic version
Frame is always 32 bits but game can reuse it later as a 16 bits RT.
Fix half screen issue with Ricky Ponting Cricket
Unfortunately it triggers texture shuffle wrongly. I hope there is no
regression.
Fix depth issue.
First issue: RT and Depth are located at the same address.
=> solution, just lookup the depth (done for any games)
Second issue: Instead to draw a X,Y rectangle, they draw a 32 pix, 4096 pix
rectangle with a FBW of 1.
=> solution, don't bother just write the depth directly
Please someone add some CRC to enable the code
// GL42 interact very badly with sw blending. GL42 uses the primitiveID to find the primitive
// that write the bad alpha value. Sw blending will force the draw to run primitive by primitive
// (therefore primitiveID will be constant to 1)
It is mostly the texture shuffle effect which is now emulated correctly on openGL
They remain in the Dx level as speedhack in particular for
* Castlevania;
* GodOfWar;
* StarOcean3;
* ValkyrieProfile2;
* RadiataStories;
Remove old commented hack: Drakengard2, ArctheLad, ReZ
Separate hacks that are only enabled in aggressive mode
It might save a couple of fps
Add a define to test the perf if we keep only the blue channel. It brokes
the code in Prince Of Persia that use the Red/Green channel... Maybe the
speed hack :( Or find a way to replace all if with a lookup table
Note: it is only supported on OpenGL currently
Code unscale the texture to ease the conversion. Quality is awful (same as before)
but I'm not sure we can support an upscaled texture
Maybe the quality loss is due to the reduction without mipmap
Maybe the best solution will be to add an hack to extract the blue channel
(with texture swizzle), and uses a "full page/screen" spirte instead.
(it would be faster too)
Note: won't be compatible with MSAA (but gl doesn't support it anyway)
// In theory new textures contain invalidated data. Still in theory a new target
// must contains the content of the GS memory.
// In practice, TC will wrongly invalidate some RT. For example due to write on the alpha
// channel but colors is still valid. Unfortunately TC doesn't support the upload of data
// in target.
//
// Cleaning the code here will likely break several games. However it might reduce
// the noise in draw call debugging. It is the main reason to enable it on debug build.
//
// From a performance point of view, it might cost a little on big upscaling
// but normally few RT are miss so it must remain reasonable.
Game can directly uploads a background or the full image in
"CTRC" buffer. Previous code was a full black screen.
It will also avoid various black screen issue in gs dump.
hidden option: preload_frame_with_gs_data
Note: impact on upscaling was not tested and it's likely broken
