- this avoids the currently used target to
become the MRU in its cache and correctly keeps
the target used by the previous draw as the MRU
during the lookup source call.
Achieved with a combination of OI+OO hacks that operate
during level loading to consolidate the rendering results
in the GS local memory.
* OI_BurnoutGames to perform small draws directly in local memory:
** improved OI_PointListPalette to draw clouds CLUT,
** improved SwSpriteRender to draw sky texture;
* OO_BurnoutGames used to download clouds texture from GPU.
The GSTextureCache::ScaleTexture method did not work
correctly when an old texture with a scale factor
different from 1 was recycled for a draw which was forced at
native resolution (the old scale factor was kept).
In GSRendererHW, reuse the method CanUseSwSpriteRender for OI_JakGames.
As in current master, 16x16 "flat" sprite draws are performed via CPU: those are palette rendering better emulated with the SwSpriteRender.
Jak games do also many 64x64 "flat" draws, but mostly for render to texture effects that are already correctly emulated in the TC, so those draws are not done via CPU (as on the contrary happens for DBZ BT games).
Improve texture cache Source objects invalidation logic taking into account overlapping with current draw.
Fixes eyes rendering for the Major in Jak 1.
Use SwSpriteRender to render sprites, which:
- fixes kaioken effect,
- fixes character outlines when upscaling,
- reduces frametime by up to 3ms with big upscaling factors.
Fixes eyes rendering in Jak games both ingame and in cutscenes.
Previous method yielded no eyes in Jak 2/3/X cutscenes.
- Generalized offset search logic with caching system (works for BW > 1
and any PSM, limited to PSMCT32 for now)
- CRC Flags mechanism for default behavior enabling in Jak games
Fixes eyes blinking in Jak games with tex in rt search
enabled.
- Target TEX0 in Source is Source TEX0 if the Source is
not build from Target, otherwise it is the Target TEX0,
allowing improved Source invalidation
Developed a new SW sprite render function, which is used to fix
Jak and Daxter colors in Jak games and to remove the old Jak games hack
which yielded wrong colors and clashed with TC search texture in RT function.
- Remove OO_JakGames hack for palette readback from framebuffer (slow,
clashes with texture in RT TC function, clashes with Target readback logic)
- Developed new method SwSpriteRender with CPU rendering logic
- Add OI_JakGames method using SwSpriteRender for CPU palette rendering (fast,
does not clash with texture in RT TC function, no readback required)
Bonus: fps also sees an improvement in Jak games 3-5 increase.
Fix GSVector4i::compare64 function by adjusting the number of iterations
needed to cover the comparison of all the elements of the input arrays,
where the number of bytes to compare is indicated in the size parameter
of the function.
The function is used only in GSdx-TC to compare CLUT arrays.
On one hand this fix closes the recent #2706 and possibly the color
regressions indicated in #2702 (which were both introduced with the new
PaletteMap mechanism, which partially replaced the GSVector4i::update
logic with the bugged GSVector4i::compare64).
On the other hand this might impact long standing wrong texture cache
lookup when palette was involved with 8-bit palette disabled (to be
verified which ones).
Close#2713Fixes#2706Fixes#2715
Enabled caching of clut copies with PaletteMap also in the case 8-bit texture is disabled, which is the default (on #2344 the caching of clut copies and palette textures was done only when 8-bit texture was enabled).
Brings moderate speedups ~10% in the most concitated parts of the ZoE2 Anubis benchmark, but may improve performance in all the cases when there are many Source objects created with clut copies to be stored.
The quality of the comments has been improved to better highlight the mechanics of the caching system.
This follows the 4th point of #2310.
The idea was to rework the current palette texture management to improve performances with games that uses multiple palettes for the same data texture.
The new management shows small to none performances improvement in almost every game in terms of FPS, and it lowers the GPU BUS usage by some percentage points in games like Baldur's Gate: Dark Alliance (9% to 7%) which uses many palettes.
The hot topic is that the performances in Zone Of The Enders 2 skyrocketed (2x), because of the fact that the game uses many palettes and a small number of textures to render it's effects.
