DMC3, Onimusha 3 rely on this behavior.
They do fullscreen rectangle with scissor, then shift by 8 pixels, not done with recursion.
So we check if it's a TS effect by checking the scissor value.
Credits to Kojin for figuring out the issue.
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.
Automatic, same as before, automatically enable based on height delta.
Force Disabled, fully disables the half bottom detection.
Force Enabled: Fully enables the half bottom detection.
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.
