gsdx changes:
Remove native resolution checkbox from GUI and rework associated code
Small changes to Windows and Linux GUI
Support 8x native resolution
Fix custom resolution width less than native width use case
This fixes the following issues when custom resolution is selected.
- When the width is smaller than the native resolution width, the
texture cache targets are removed on every Vsync signal, causing a
black screen issue.
- The texture cache code needs a 1 returned for the custom resolution
upscale multiplier or there'll be some really funny graphical issues.
It also removes unnecessary GetConfig (which I think unconditionally
does a a file read on Windows) calls if the width was increased - the
upscale multiplier is already stored, and the custom resolution width
and height calls are now unnecessary.
Also fix some whitespace issues.
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.
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.
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...
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
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
To clear a (W, H) RT/Depth, GS can only send a (W , H/2) primitive with
a Z (or RT) pointer in the middle of the buffer
Top-half will be cleared by the color (or the depth).
Bottom-half will be cleared by the depth (or the color).
Code isn't enabled yet but it was tested with success on GoW2.
Gow uses 24 bits buffer, so only color is updated but blending is configured as Cd
so it is a NOP
In this case, we don't lookup the target in the texture cache. It reduces the complexity
to handle depth which can be located at same address as RT
Note: please test DX renderer
Old way various check boxes to configure the plugin
New way an unified drop down list
* Level 0 (dev only) => disable (mostly) all hacks and auto skip depth.
* Level 1 (dev only ) => enable oi/oo/cu hacks, others remains disabled
* Level 2 (GL) => enable most hacks except a couple of one that were fixed on openGL (speed impact)
* Level 3 (DX) => enable all hacks
* Level 4 => enable also aggresive CRC
Note: windows gui must be updated, and it will be nice to create a global tooltip
-Last commit broke Snowblind games again
-Width now based on output circuit
-Try to use the smallest possible while being at least the size of the screen
The idea is to easily extract bad frame from gs dump and to compare them
with the sw renderer.
Here the summary of the options:
savet => dump all input textures
save => dump the render target
savez => dump the depth buffer
savef => dump the frame
