weihuoya: Which hardware did you test it on?

#4 Updated by weihuoya about 2 years ago

samsung s7edge, 820

#5 Updated by weihuoya about 2 years ago

Okami drawing screen require logic ops but logic ops aren't available on android device. it can't get fixed. so sad.

#6 Updated by JMC4789 about 2 years ago

We should make a global issue for these features.

Even if Android doesn't support logicops, it's possible we could have a (slow?) fallback that at least lets it get emulated in games that require it.

#7 Updated by weihuoya about 2 years ago

yeah, we can use framebuffer fetch in opengl and do shader logic ops.

#8 Updated by Stenzek about 2 years ago

It's only a fix for OpenGL, though. Hopefully at some point Vulkan will get a EXT_shader_framebuffer_fetch equivalent...

#9 Updated by weihuoya about 2 years ago

find these games have graphic issues without logic ops support:
Okami, Mario Kart Wii, Prince of Persia: Warrior Within, Prince of Persia: The Forgotten Sands, Resident Evil Code Veronica X, Skies Of Arcadia Legends, The Legend of Zelda: Skyward Sword.
