Xenosaga handles the half bottom as an vertex offset instead of a buffer
offset which does the effect twice.
Half bottom won't trigger a cache miss that skip the draw because it is
still the normal buffer but with a vertices offset.
Issue #3147
Previous skip value 6 wasn't enough and caused some visual issues on the
ntsc version. Use value of 8 instead.
Issue reported by ozzie212121 on discord.
Effect is properly rendered with depth emulation, so far only Burnout
Revenge triggered the crc hack from my testing.
Triggering the draw is done when the player car crashes.
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.
It will allow to render the shadows properly.
Rendering pattern is:
Save RG channel with a kind of a TS (replaced by a copy in this hack),
compute shadow in RG,
save result in alpha with a TS,
Restore RG channel that we previously copied to render shadows.
Seems like Texture shuffle/depth is not handled properly in all cases so
revert the change until we fix it properly. Move it to gl level too.

Typical shuffle case is 1/2 height so other half is undesired
In dbz we split the depth buffer.
- Sample first half, write to `0x0`.
- Sample second half, write to `0x800`
- Finally, sample `0x0` though `0xffc`
Crash Twinsanity is a similar case.
A short summary how d3d option behaves compared to gl.
None d3d-> behaves the same
Basic d3d-> even less than 1/3 of Basic opengl.
Medium d3d -> less than 1/3 of Basic opengl.
High d3d -> 1/3 of Basic opengl.
Note: Medium and High options are mostly intended for debug use.
It works on games such as Fifa Street 1 and 2 (character and stage
rendering), mission impossible operation surma (shadow rendering).
It needs at least Basic level of blending enabled on d3d11.
Follow up from the previous commit which is bypassing the texture cache
when the frame buffer is sampled.
Crc hacks are no longer needed on opengl.
Note: it requires at least Basic blending support.
Proof of concept. It should provide a huge speedup when accurate
blending is enabled for tri-ace / Jak / R&C (shadow rendering).
See #2894
Need PR#2892
v2: Add const + comment to explain that code isn't ideal.
