ive heard others talk about this issue in other games, but i think ive only
seen it in mario kart wii myself. the bloom glow is offset down and to the
right on everything (ghosts, karts/riders, cubes). best seen here on the

ok i havent updated in a week or so, but i just did and noticed something. the bloom
offset has changed! look at this picture. its even more further to the right and
down. just gotta track down what did this and maybe it can be fixed?

COrrect me if im worng, but i noticed if you use ?xSSSA options, the bloom offset effects is reduced right? I noticed it in MH3 when enabling 9xSSSA, the bloom is nearly perfect..... but not playable for me as it slowdowns the game ALOT!!!!! ( my gc card cannot handle 9xSSSA and strangely 4xSSSA too :( )

Donkey Kong Country Returns also suffers from this issue. It's good to see here: http://img6.imageshack.us/img6/3672/donkeykongredglow2.png

huh? that's new to me...anyway, there is a projection hack that deals with it for now.

Fwiw, is this issue also present with DX11 in Mario Kart Wii for native EFB scaling?
There's numerous reasons for this issue I think: One being some off-by-one errors in our viewport/scissor rect code, the other one being in D3D9 that native HW uses floating points for viewports but D3D9 integers (which will cause some inaccuracy).
Also, I'm beginning to doubt whether this issue can be fixed at all for higher resolutions. We can't correctly upscale all viewport/scissor rect coordinates which f*cks up things quite a bit...
The bloom offset in MH3 can be fixed by enabling EFB access IIRC.

hmhmhm...I just tried with DX11 and EFB scale set to 1x (and scaled copy disabled) - that would be native, right?
well, my findings are that in Mario Kart Wii it indeed is less strong...I'm actually not even sure if it's wrong at all...there's a bit of bloom looking over the edges but I cannot tell if that's an original effect to make things a bit more glowy...my Wii is broken so I can't test on that.
However, I also tested Little King's Story and there it doesn't seem to have changed.
Ah, btw. I made a screenshot in that game a few days ago cuz the issue is nicely well to see there (and that's even with "Skies of Arcadia"-proj hack enabled, normally it's even worse:

I have been testing this with Monster Hunter mainly and here is what I noticed:. It is directly affected by the internal resolution.
The higher the internal resolution, the better the picture.
Enable Hotkeys and test this by playing with the "3" button which changes the internal resolution. You will notice that as you increase it, the effect gets closer and closer to where it should be. Currently 4x gives me the best image and the problem is almost gone but not entirely.
