* 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.
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
* Dump context before the increase of s_n
=> aligned with the global call number
* Don't print colclip not supported when it is optimized away
* dettach the input texture when it is useless
=> avoid to show a wrong texture in the debugger
