Will use integral coordinate to avoid any rescaling.
Bilinear interpolation isn't supported. I don't think it is allowed to
filter a depth texture anyway.
The hypothesis is that game will use a depth (aka Z32/Z24/Z16/Z16S)
format when sampling depth texture as color. Technically one could use
a standard color format but block/pixel order won't be the same.
(otherwise I'm screwed)
=> Hypothesis invalid on GoW. They just do a scrambled rendering...
Lookup info:
* The first searched list is the depth pool as we search a depth
texture.
* 2nd one is the render target pool (if a depth was converted to a
render target already)
To avoid any CPU overhead, the source will be a pointer to the real texture
* Conversion (if float texture) will be done on the fly by the shader (GPU).
* Relative rescaling won't be supported. Texture must be fetched with
integral coordinate
Cache page coverage of texture into a hash map
Test done on Champion of Norrath (paltex + DisablePartialInvalidation)
Profiler:
Self of GSTextureCache::SourceMap::Add 5.39% => 0.23%

Hard to measure on CoN as it depends on memory transfer. Seem to be 5-10 fps faster.
This reverts commit 53690cf9d0.
Quoting user:
For aliasing, the option allow of reduce a little but always very
visible compared with DX11 even with anisotropic OFF, , furthermore
many textures bug added with option activated (predictable but not see
on DX11 with anisotropic ON).
TL;DR doesn't worth it.
Note: it seem to work on DX because DX uses HW texturing in clamp region
mode (and others invalid case). OpenGL uses SW texturing to ensure accuracy
* keep a reference of program/pipeline created to ease the deletion
* extend a bit the API to support multiple pipeline
Final goal will be to use a pre link pipeline for SW shaders. And uses
the default pipeline for HW shaders.
By default, anisotropic filtering was disabled when textures aren't countinuous.
This hack allows to force it. It can help to reduce aliasing but it would create
unexpected effect on texture boundaries.
Again, someone ought to add the option on Windows too
Someone ought to add the Windows option too (and DisablePartialInvalidation too)
It might break a couple of games but most of them run better with depth enabled.
Fixes an issue with the D3D backends crashing if the configure dialog
is accessed and ok is pressed. The D3Dcompiler dll is freed and a null
pointer is dereferenced.
It might break gsdxgui but GSshutdown really should not be called unless
GSdx is shutting down. GSDumpGUI on Windows provides the same (or
better) functionality.
* Silent Hill 2 doesn't need the CRC hack
* GSRenderer: no need to explicitly set bottom value for r.
* Texture Cache: Removed a check which couldn't possibly enter true
branch.
For some reason some Windows 7 systems (most are unaffected) cannot cope
with LoadLibraryEx and return error code 87 - "The parameter is
incorrect".
Switch to using LoadLibrary instead for any case where Windows 7 is
expected to successfully load the requested dll. Potentially Windows
Vista is also affected.
So let's increase the height. It will increase the memory requirement on some games
v2: try to do it automatically
(not sure it will useful as most game will requires it)
v3: let's back to an hardcoded 1280 size. It generates too much issue
Try to avoid random black screen frame
v2: don't force the preload hack on the frame
It creates a ghost image over FMV
v3: support offset within a frame
The long story:
Game blits FMV far aways of the RT which is actually the input of the RO texture...
Currently GSdx suffers of 2 bugs.
1/ RT is too small
2/ texture isn't properly updated with the rendered value. Texture is invalidated
but it reads back the pixels from the GS memory whereas the correct
value is located on the GPU.
This commit will replace the standard draw by a manual blit. Therefore it avoid
size issue and bad upscaling issue.
v2:
* Use various copy to be more compatible with dx api
* Move all part of the hack info the BlitFMV function
v3: add log message
It often happens the game try to upload the FMV directly which typically
gave a black screen.
Commit fix rules of roses and I hope various black screen FMV
Performance impact must be tested, and I'm afraid of strange texture cache behavior.
V2: check the size of the transfer too
V3: add support of 16 bits format
V4: avoid division by 0
Using D3DX11 requires the end user to install the DirectX redist files.
Switch to using D3DCompile, and distribute D3DCompiler_47.dll for
Windows Vista, 7 and 8 users (Windows 8.1 onwards supplies
D3DCompiler_47.dll with the OS).
It actually removes the previous hack that read the full target.
Unfortunately snowblind engine game uses big target so the read is very big too (1280x448)
which is killer for the perf. Whereas the game requires only 24x12 texels
Give a 2x speed boost on Champion of Norrath !!!
Games uses very special texture with a lots of repeating.
It is much faster to send the full texture rather than trying to partially invalidate it.
On my gs dump:
FPS: 29 => 68 !
Basically I ran
find . -name "*.vcxproj" -exec sed -i -e 's/_xp//' {} \;
This will likely break XP, but it paves the way on Windows for a PCSX2
that does not require the DirectX redistributables to be installed for
Windows 8, 8.1 and 10 users. Windows Vista and 7 users will still require
the DirectX redistributable files for XInput and XAudio, though PCSX2
should still be capable of running if a user does not actually use either
of them.
All GL4 extensions supported by DX10 class GPU will be soon mandatory
Namely:
* GL_ARB_copy_image
* GL_ARB_texture_barrier
* GL_ARB_clip_control
* GL_ARB_direct_state_access
* GL_ARB_separate_shader_objects
* GL_ARB_buffer_storage
There are likely few games (RE4) which constantly change the FBW register value causing the framebuffer width to be updated at every interval. Adding a safe limit (512) similar to frame buffer height would prevent such constant changes of the framebuffer width when FBW changes once again to an even lower value.
Valid values for png_compression_level are from 0 (no compression) to 9
(max compression). The default is 1.
v2: Use zlib Z_BEST_SPEED (1) and Z_BEST_COMPRESSION (9) defines.
The following patch uses the height value of the display rectangle rather than make an estimation of the Frame buffer height when the game uses a non-referenceable height (or) width.
Don't lookup a depth buffer if depth test is always pass without write
Boost performance on Tekken5 when depth emulation is enabled in openGL
(Tekken5 sets same address for both the RT and the depth but depth is disabled)
v2:
Keep ds if DATE is enabled (some implementation uses a stencil buffer)
Be more aggressive to avoid an useless depth lookup
Texture coordinate could be dummy/float/int integral/int normalized.
Old behavior:
* VS was in charge to select the texture coordinate
* int integral format wasn't supported
New behavior:
* Always compute all formats
* FS will be in charge to select the good format
Impact:
* VS will be slightly slower but it reduces shaders permutation from
little to 0 (won't be bad for CPU)
* FS speed isn't impacted as 2 separate code paths were already required
to support both format
* Rasterizer will be 33% slower but unlikely to be the limited factor of
the GPU
* In future we could directly use the integral format in the FS.
V2: remove useless PSin_t
It would be on by default. Unsafe & fast path.
The hack is a security if someone encounters any issue
v2: update Windows gui file
v3: fix typo in tooltip and linux gui
Visual Studio Find and Replace can only be trusted if all the files are
included in the project. I suppose it's time to add any missing files
to the relevant projects...
The old implementation saved the current value of a GSSetting as uint in
a field called 'id'. The implementation of GSSettings suggests that
GSSettings could be saved in a database with id as primary key. This
would require a translation look up from id to value but could have all
advantages of a database. However the interface to GSSetting was never
implemented like that.
In the new implementation GSSetting has a 'value' field that stores an
int representative value of the desired state. Additionally the
constructor is 'overloaded' as template to reduce casting in the
consumer code. However all consumer values need to be castable to int.
Accordingly combobox initialization was adjusted.
Initially it was free to do the SW blending because safe fbmask
will already do a sw blending.
Unsafe version uses a fast path with a limited blending. Therefore
SW blending isn't free anymore.
Improve the speed of the previous speed hack (xenosaga 1)
The hack relies on the undefined behavior of the hardware so it can
potentially generate rendering corruption.
This new hack drops the cache flusing when only the alpha channel is masked.
Alpha is a direct copy of the fragment. Normally masked bits will be constant
everywhere (RT, FS output, texture cache) so it would likely work.
Just in case, code is only enabled with the new shiny hack
The previous behaviour loaded the saved renderer config whenever the
adapter combobox was changed. The renderer will now only change if the
new adapter doesn't support the currently selected renderer (i.e
Direct3D11 might not be supported, so it'll revert to Direct3D 9).
Fixes#1080.
The Wild Arms Offset text was slightly cut off due to the label being
too small. Make the dialog slightly wider so the full text will fit.
Someone should probably make the dialog look nicer at some point.
Avoid a crash on Onimusha3 (PAL 60HZ)
In theory it will be better to find the root cause of overflow. I.e. somewhere in this
code below. Dirty rectangle is too big.
***********************************************************************
if(rowsize > 0 && offset % rowsize == 0)
{
int y = GSLocalMemory::m_psm[psm].pgs.y * offset / rowsize;
if(r.bottom > y)
{
GL_CACHE("TC: Dirty After Target(%s) %d (0x%x)", to_string(type),
t->m_texture ? t->m_texture->GetID() : 0,
t->m_TEX0.TBP0);
// TODO: do not add this rect above too
t->m_dirty.push_back(GSDirtyRect(GSVector4i(r.left, r.top - y, r.right, r.bottom - y), psm));
t->m_TEX0.TBW = bw;
continue;
}
}
***********************************************************************
So as a temporary solution (that will likely stay for a couple of
years), buffers were increased.
Height of the dirty rectangle must be the GS size of the RT. Of course
RT doesn't have any height so we compute the max safest value.
Fix issue #987
Candidate for 1.4 release
Both the Linux and Windows config dialogs now have a TV Shaders combobox,
so the F7 toggle can be made temporary. This makes the hotkey behaviour
consistent with all the other hotkeys.
The old one isn't working. I don't think there's a URL that redirects to
whatever language the user is using (unless my browser settings are
wrong), so I've just used the English US URL.
1. Add GS_Renderer Enum
Replace all instances of int/uint32 renderer identifier by a strongly
typed enum and appropriate casts.
Only instances in GS[*].cpp/h classes were touched. GPU[*].cpp/h classes
do not to follow the same convention.
2. Add default renderer according to OS
The default renderer is OS dependent (Win -> Dx9HW, others -> OGLHW).
Consequently one should always check againt the appropriate default
value on config load.
The old behaviour was only - if a at all - problematic if the respective
element in the gsdx.ini was missing and probably even then didn't create
issues. The current implementation is still more stable and does not
depend on the implementation of GS.cpp -> GetConfig()
The following patch adds Mipmap option (software mode exclusive) and Preload Data Frame (Hardware mode exclusive) to the GSDX plugin settings for debug purposes.
The goal is to check the impact on game that have wrong RT content.
It helps a bit Smash Court Tennis Pro Tournament 2 but the game suffers
another texture cache bug. (RT BW is 10 whereas texture BW is 8)
Note: Armored Core: Last Raven must be tested (only game so far
that rely on the option and I didn't want to add a new one).
Typical wrong draw:
1/ draw in 32 bits
2/ draw in 24 bits
3/ Use alpha as a texure. (Must reuse the GPU data)
4/ Write alpha from EE
5/ Use alpha as a texure. (Must upload new data)
This commit fixes the step 5.
