Akash b871c6b46f GSDX-TextureCache: Generalize scaling equation
Previously the dedicated custom resolution scaling equation was ignored for the second SetScale() call, generalizing the equations will also fix the DMC scaling issue on custom resolution. Also remove unnecessary checks for null on scale factors. The possibility for having a null scale factor value only exists on custom resolution and it will only happen on cases where the output circuit isn't ready yet. So the ideal way would be to handle all the required conditions of output circuit on "m_renderer->CanUpscale()" itself.

Gregory Hainaut a4658eac24 gsdx hw: allow overlapping of texture (alpha) and framebuffer (RGB)
Fix HUD on Berserk

v2: use fbmask instead of hacking the target format to 24 bits.

Gregory Hainaut f712c5c6d0 gsdx tc: use GSLocalMemory::m_psm instead of hardcoded value 2016-05-05 12:19:25 +02:00
Gregory Hainaut 826b38c47a gsdx tc: use array in GSOffset to store texture coverage
GSOffset is already based on a lookup of PSM/BP/BW. Coverage only adds
the size parameters (so only 256 possibilities)

It replaces the hash lookup with a free array access.

Gregory Hainaut 7d191ebf8e gsdx tc: load palette for pseudo 8 bits depth
Rendering is still broken but I'm afraid it will need a dedicated shader

Gregory Hainaut 49d175b677 gsdx tc: allow to create a dummy Source without tons of memory allocation
It makes shared texture virtually free from the CPU PoV.
2016-04-24 22:30:56 +02:00
Gregory Hainaut 583de1bf0b gsdx tc: add a dedicated function to lookup a depth source
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

Gregory Hainaut 9ee090a36e gsdx tc: add a shareable texture flag

Gregory Hainaut fa1377a8ee gsdx tc: reduce texture cache overhead
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%
Self of GSTextureCache::LookupSource 15.27% => 10.82%

Hard to measure on CoN as it depends on memory transfer. Seem to be 5-10 fps faster.

Gregory Hainaut 72d43b2e56 gsdx tc: add an invalidation procedure to drop sub rt

2016-04-04 21:29:31 +02:00
Gregory Hainaut d922225e69 gsdx tc:invalidate RT when a texture is written inside it
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

Gregory Hainaut c43b1ac201 gsdx tc: extend the fast invalidation hack to limit the size of target read
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 !!!

Gregory Hainaut 46a4d2dc47 gsdx-tc: add UserHacks_DisablePartialInvalidation for snowblind engine game
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 !

Gregory Hainaut cee0fde940 gsdx-tc: improve support of TEXA register
* 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.

Gregory Hainaut e66aac8ab7 gsdx-hw: add an hidden option to preload the final frame with GS mem data
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

Gregory Hainaut 85543db094 gsdx-tc: trace the alpha channel update in TC
Improve the rendering in MGS3 (even if the game is still broken
due to others TC issues)

// Typical bug (MGS3 blue cloud):
// 1/ RT used as 32 bits => alpha channel written
// 2/ RT used as 24 bits => no update of alpha channel
// 3/ Lookup of texture that used alpha channel as index, HasSharedBits will return false
//    because of the previous draw call format
//
// Solution: consider the RT as 32 bits if the alpha was used in the past

Gregory Hainaut 580d177951 gsdx: improve commit 11708486d8

(RT used as a palette texture).

Gregory Hainaut 11708486d8 gsdx: allow to control the filtering of texture cache
When the RT is used as an input texture, we need to rescale it.

Previous behavior was to always uses a linear filtering (more smooth).
Unfortunately it broke some games that expected an exact value like Star Ocean 3

This commit will disable the linear filtering in normal filtering mode (filter = 0
or filter = 2)

This way, shadow of Star Ocean 3 will appear correctly in upscaling (not
100% perfect but can't do better)

Note: SO3 only requires a nearest sampling of the alpha channel but
I don't know the behavior for others games.

Slight adjustments to positions in the GUI also (OCD'd the spacing a little :P)

sudonim1@gmail.com e8257df98d GSDX: made the paletted texture handling in the cache a bit more sensible to my eyes and implemented interpolation of palette entries for pixels in paletted textures when using the 8 bit textures option. Regressions in some games I think, such as Virtual On (which is very broken anyway), need to investigate what made them work (to some degree) before. Seems to change some performance characteristics favourably to my surprise, but I might just be bad at remembering framerates.

ramapcsx2 1595136a9d GSdx:
Another refinement to the Wild Arms hack by KrossX.
The hack now only applies to one kind of geometry (sent using  the unpacked UV handler).
This works nicer in Wild Arms as it fixes "jumpy" characters.

ramapcsx2 b25aec19c1 GSdx:
Adding KrossX's Wild Arms text alignment hack to the new dialog box. This hack is actually very interesting for a number of games. It should work well in cases where game designers adjusted everything pixel perfect for the GS, that usually breaks with upscaling. 
It should be generalized and renamed later.
