Yeah it's supposed to and yeah it should be noted.

meanwhile, it would nice if anyone could put up a list of games where issues are resolved due to round offset hack. It would be better to finalize the description for the hack before making a PR for it.

Latest debug build crashes with both opengl and directx on every game i've tested so far. regular dev build seems fine

Which build exactly?

Ok I understand the issue. I will fix it.

Edit: it must be good now

@shinra358
Could the unaligned texture be linked to anisotropy? OpenGL doesn't support it yet.

meanwhile, it would nice if anyone could put up a list of games where issues are resolved due to round offset hack. It would be better to finalize the description for the hack before making a PR for it.

driving emotion type-s

fatal fury battle archives

street fighter 3 Third Strike (partially improves by a great deal)

unrelated: namco x capcom (align sprite not working on videos)


If more tweaking can be done, probably could fix sf3ts uprezzing issue completely.

FFX line in the menu are improved with the the state 2 of round hack this as far as i can tell TF still works though. that the only game i have that improved by this hack other then Xenosaga 2 lines in the start menu being fixed at cost of TF.

[Bible Black]

Drakengard 2s lines are fixed while upscaling as well, sadly it still has other ***** up stuff.

In the meantime, I implement 2 new options to improve accuracy (openGL only)

accurate_date = 1

It is replacement of the hack AlphaStencil except it will work in all situations. Performance seems to be comparable

accurate_blend = 1

Improve blend support to support special blending mode. You know those errors messages.

Impossible blend for D3D: (Cd - Cs) * As + Cd
Impossible blend for D3D: (Cs - 0) * As + Cs
Impossible blend for D3D: (Cd - Cs) * Ad + Cd
Impossible blend for D3D: (Cd - Cs) * As + Cd
Impossible blend for D3D: (Cd - Cs) * 64 >> 7 + Cd
Impossible blend for D3D: (Cs - 0) * As + Cs
Impossible blend for D3D: (Cs - 0) * 128 >> 7 + Cs
Impossible blend for D3D: (Cs - 0) * As + Cs

Impressive work with the impossible blends gregory. Keep up the great work!

By the way, you need a driver that support GL_ARB_texture_barrier extension. I guess Nvidia implements its only on DX11 class GPU. I don't know the status for AMD.

Basically every Namco game I have is fixed with this. From Tekken 5 to ace combat games.

According to mesa release notes it should be available starting from nvidia dx10 class hardware, and AMD dx9.
