Default copy-constructor is eight 32 bits move
GSRendererOGL::Lines2Sprites code shrinks from 510B to 398B
(loop of the function 296B => 181B). Hopefully it will reduce the cost
to convert line to sprite on the CPU (i.e. when geometry shader is disabled)
It impacts all renderers. It ought to fix issue in GTA radiosity,
Shadows in Jak series. (note shadows will suck in upscaling)
Implementation is really brutal. Expect a massive slow down, but at least we can test the effect
easily.
Normally perf impact will remain reasonable if the game doesn't use a Read-Write effect
Performances number are welcomes (my guess is really awful in HW mode, slow in SW mode).
You can enable it with "UserHacks_AutoFlush = 1"
GS memory is only 4MB but rendering is allowed to be 2048x2048
with 32 bits format (so 16MB). Technically the frame/depth buffer can start
at the end of the GS memory. Let's not waste too much memory.
Fix crash with BASARAX
(game draws a 2048x1664 32 bits area)
The hack only fix the HW renderer but not the SW renderer. However I'm not sure
the issue is from GSdx.
The hack will disable alpha test that used to generate empty draw call.
Manual gives all setup to upload a palette from the host. But nothing forbid to render
directly in the palette buffer. (GS rule nb 1, there is no rule ^^)
Fix Virtua Fighter 2 dark colors
However I'm not sure we can fix HW renderer. Rendering is done on the GPU but palette
handling is done on the CPU... So we need to read back data (ouch, and slow). A quick
test didn't get the expected results. Potentially there are others bugs (aka not gonna
happen on the HW renderer)
Fix motocross mania missing texture. Close#1319
As far as I understand, transfer is initialized in DIR. But the real
write only occured later so the blit buffer could have been overwritten
by a new value.
BLIT 0 13700
TREG 40 40
DIR 0 0
BLIT 0 13f00 <=== the bad guy
Write! ... => 0x3f00 W:1 F:C_32 (DIR 00), dPos(0 0) size(64 64)
v2: set a value in m_tr.m_blit for load state
It creates a regression on game that uses a small temporary target to
upload textures of various sizes. Inital code was done to handle direct
frame write (background, FMV) so big target
Purpose is to control the filtering when final image is displayed on the screen
Could improve the sharpness of the output in some games (ofc, it will be pixelated)
When depth primitive is constant and depth test is greater or equal, we can
execute the depth write after color (depth status will only depends on the initial
value)
New case for RGB_ONLY ate:
If the blending equation uses a fixed alpha or a source alpha. We can postpone the alpha write
in a 2nd pass.
If depth can also be postponed, we can guarantee the order of correctness of the value.
1st pass => do RGB
2nd pass => do Alpha & Depth
It fixed Stuntman letter rendering :) Remaining of the game is still broken :(
At higher resolutions it takes too much time to save a screenshot at the
maximum compression level. So let's allow the user to set the
compression level.
This re-uses the png_compression_level setting. The default compression
level is 1 for speed, but if the user wishes to increase the compression
level (without using an external tool) and doesn't mind if the
screenshot takes more time to save then they can increase the
compression level up to a maximum of 9 (which can take quite a while).
Fixes#1527.
PNG_LIBRARIES adds both libpng and zlib to the command line.
PNG_LIBRARY only adds libpng to the linker command line, and the cmake
documentation also suggests not to use it.
Value seems wrongly rounded and you can't distinguish 0xFFFF from 0xFFFE
Instead check that depth is constant for the draw call and the value from the vertex buffer
Fix recent regression on GTA (and likely various games)
In FB_ONLY mode the alpha test impacts (discard) only the depth value.
If there is no depth buffer, we don't care about depth write. So alpha
test is useless and we can do the draw with a single draw call and no program
switch
Extend GSVector to support float move
Initial code likely used integer move for performance reason. However due to
the nan correction, register is now in float domain.
CID 168626 (#1 of 1): Uninitialized scalar field
uninit_member: Non-static class member m_end_block is not initialized in this constructor nor in any functions that it calls.
Fix rendering issue on letters on Kengo/burnout 3/...
Default algo will execute the alpha test in 2 passes. However due to blending
you can't handle accurately the color.
Fortunately for us, the rendering uses an always pass depth test so you
can execute first all the color rendering (which doesn't depends on the alpha test)
And then the depth part which depends on the alpha test.
* Code was factorized a bit with the help of max_z
* Add an extra optimization if test is ZTST_GEQUAL and min z value is
the biggest value. Z test will always be pass.
Note: due to float rounding (23 bits mantissa vs 24 bits depth) the test
is done against 0xFF_FFFE and not 0xFF_FFFF. It is wrong but GPU will
also use float so impact will be null.
The solution files are unused and for ancient Visual Studio versions -
GSDumpGUI has its own solution file, and bin2cpp is included in the main
solution file.
The property sheets have either fallen out of use or were never used in
the first place.
Fixes a regression introduced by 46ba9aa117,
where the Linux GS replayer would always use the options in inis/GSdx.ini
(or use the default options if that doesn't exist) to replay the dump,
instead of using the GSdx.ini from the specified ini folder.
Update done on f712c5c6d0
Previous code use the size of the draw to compute latest block. I
don't know why I use .x/.y which are the origin offset so the start of the block.
Check the instruction set first in GPUinit, GPUconfigure and GPUtext
to prevent unsupported vector instructions from being executed.
Move the vector initialisation in GPUinit to a separate function - it
avoids a vzeroupper instruction.
vector push_back causes a SIGILL signal on a Nehalem (SSE4.2) QEMU VM
when compiled with GCC 6.1.1.
However, an empty constructor causes illegal instruction exceptions to be
generated on a Windows VM.
So here's an inbetween that looks stupid but works on what I've tested.
Fix#1457 (GTA)
The game uses a depth format for a pure color buffer (cokes do ravage
in gaming industry)
However I'm really afraid that it migth break another effect in other games.
Combine all the different configurations together so the project files
are more generic and maintainable.
Also standardise the layout so all the project files will be similar and
all have the same standard elements (even if empty).
Add 64-bit configurations.
Additional specifics:
spu2-x: FLOAT_SAMPLES preprocessor definition removed since it's unused.
Use a relaxed atomic to read the exit variable in the hot path
Wait that exit is deasserted in the destructor, so we are sure the
thread will "soon" return
Value could range from 1 to 9. Default is 4 and it is potentially the
best option. Feel free to test some values on your system, behavior
might depends on the core number and thread number
Value is exponential so 4 is 2 times more pixels than 3.
Small value increased thread overhead, big value increase wait/sync latency
memory overhead by thead is only 256KB
However it will reduce the probability to block the push thread to nearly 0
I tested a couple of dumps and only manage 4000 element with 1 extrathread.
Add a factor 2 on the VRAM to get the quantity of available memory for the textures.
The driver is allowed to put some textures in RAM. Of course it is bad for performance
but it won't crash.
Due to the 4GB by process limit, I keep a (reasonable) maximum of 3.8GB.
In order to avoid a crash when memory is too low an exception will be risen
with no guarantee on rendering and big performance impact. In this situation
you ought to reduce upscaling/disable large framebuffer.
* Does the first vsync (start counter) after the sleep
* Dump data after the rendering, avoid to count extra destructor,sleep time
* Dump data into a basic csv file (if people want nice graph)

It creates some slowdowns for unknown reason. My best hypothesis is
that stencil will be cleared too which is slow.
Let's keep the code for the future when stencil will be dropped.
Fix#1420
If baseline and display rectangle offsets differ by small values then consider the status of frame memory offsets, prevents blurring on Tenchu: Fatal Shadows, Worms 3D, ProStroke Golf, Vexx
* Improve frame buffer height management on custom resolution. Width seems to be fine with the same size as scaled image output.
* Prevent offset issues on Persona 3 based on the data from merge circuit.
Note: Fixes custom resolution upscaling on ICO 50Hz/60Hz mode when large frame buffer is enabled. previously 60Hz mode only displayed half of the screen and 50Hz mode only worked due to the scissor hack.
* Ignore Frame memory offsets for calculating dimensions value of display rectangle.
* Remove hack which limited scaling size based on the scissor value.
Note: With the following commit, SilentHill 2 now properly outputs the desired resolution by the users on custom resolution. Previously if we set 1024 x 1024 , it'll output a lower height value which was caused by the hack removed on this commit.
It ought to be the same in performance but code will be easier this way
v2: print the sync status
v3: use a performance print so it doesn't spam the console
* Support Mesa Nouveau IR (free driver for Nvidia's GPU)
=> Print intermediate representation + final shader
=> Dump GPR usage
* Move dumped shader in /tmp/GSdx_Shader/<sub_dir>
=> Avoid the landing of 3 thousands of files in $PWD ^^
* Use function instead of macro
Using __declspec(dllexport) causes duplicate export warnings to be
generated when compiling 64-bit builds. Name mangling also occurs on
functions that are exported this way, so it doesn't actually work with
the plugin system, which uses unmangled names.
The module definition file exports the functions without name mangling
and is sufficient on its own.
Increase the performance on the free driver (Nouveau)
Currently the driver validates all UBO when only 1 is updated. It
is clearly a bad idea to put all UBO in a single common headers.
find . -name *.vcxproj -exec sed -i -e '/user.props/d' {} \;
Microsoft recommends against using .user files. From
https://msdn.microsoft.com/en-us/library/669zx6zc.aspx :
"The best practice is to delete the reference to them in Property
Manager to ensure that your projects operate independently of any
per-user, per-computer settings. This is important to ensure correct
behaviour in a SCC (source code control) environment."
If you cannot compile SPU2-X after this commit (since that still relies
on the old DirectX SDK), you'll need to fix your build environment.
Legacy GPU:
Older driver will be broken.
Still supported GPU:
Please upgrade to the latest AMD driver 16.5.2 or 16.5.3 (and prey that future driver will still work)
Potential issue
* miss a default value
* Renderer is DX9 again on windows
* Case issue
* Same default for all code paths
* overload of GetConfig
v2: separate specific OS option
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.
* 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
It would requires some texture dynamic width convert shaders.
So as a quick solution, let's add a new CRC hack.
For issue #1362 (granted the CRC is correct)
Faster :) Reduce further the cost of accurate date
The optimization will clear the stencil to 1. So all pixels will have a
single sample that pass both the depth & stencil test. No primitive
overlaps So the destination alpha test can be done directly in the
shader.
Game often uses date to allow a single pixel pass. If this
use case is detected, stencil buffer will be cleared after first pixels
that pass both depth&stencil test.
It seems to reduce the load on the GPU.
Note: with the help of texture barriere, maybe we could implement the algo
with a single pass.
If a color buffer is still attached and is smaller than depth buffer,
the latter won't be fully cleared.
As a faster alternative, use GL4.4 clear texture function. Avoid to fiddle with
framebuffer and pixel tests.
Fix #1362x Ar Tolenico 2 map clip
So just reuse GT hle shader :) Acid stage is now correct. However it might need
some tuning for others stages.
Still look awful with uspcaled resolution (note internal game framebuffer is around 160x128)
