Dolphin, the GameCube and Wii emulator - Forums

Squall, the last two shots are at 2x and 3x. There's even a difference although slight between 2x and 3x internal resolution/efb scale. Basically 2x efb scale is going to give the same quality that 2.25x SSAA does, that is what's being discussed in this thread.

Quote:And to illustrate my point, I present the following evidence. SSAA disabled and efb scale tested at 1x (native), 2x, and 3x respectively. Notice how the edges are smoothed at as you change the internal resolution, just like with AA?

The last two pictures had to be compressed a bit in order to upload them. I will test again and upload the pictures in full quality somewhere since the forum only allows a max of 500 kb for an image. However I feel these should suffice and the difference quite noticeable.

There's some minor jaggies, but it does smooth the edges out quite a bit. It improves the quality of the entire scene, not just the edges.

Yes for the same reason that increasing the resolution of a pc game decreases aliasing. More resolution = less aliasing. But you are not actually anti-aliasing the scene. As evidenced by the fact that their is still a lot of aliasing even with 3xefb scale. Now if you are running at a lower resolution like me (1366 x 768) then using a high efb scale like 3x does actually anti-alias the scene since the efb is being scaled to a higher resolution than my screen resolution, which is essentially what SSAA does. Understand my point?

Simply put no matter how high you set the efb scale with a high resolution monitor you will still have aliasing. And no matter how high you set SSAA you will still have a blurry image if you don't increase the efb scale. They serve two different purposes.

im sorry, but no it doesn't.

Have you actually seen the 2.25x SSAA option back when it was implemented in Dolphin? Setting the internal resolution at 2x looks just as good or better than 2.25x SSAA, it was quite poor compared to the quality that 4x SSAA and 9x SSAA offers.

why are we even comparing and saying "this OR that"? We could have both, and it'd be a good team 8)

i used both, but 2x EFB was nothing compared to the JAGGY KILLING that 2.5SSAA provided.

4xAA and 1x EFB



Not much difference if any.

What is your AA setting set to in your graphic card's control panel ?

I beg to differ, there's barely any jaggies at 2x or 3x in the screenshots I posted. It is about equal in terms of quality compared to 2.25x SSAA, if not equal. Using 2.25x isn't jaggie free like you make it sound, truly jaggie free would be using 4x SSAA or 9x SSAA and there is even some slight aliasing at 4x SSAA as well.

I guess it also depends a bit on the size and format of your monitor...

@ MFZ: I wouldn't go on about those comparisons...as I said, apart from Chris in the back, it's just a 2D pre-renderered screen; AA doesn't even touch it. Bi-/Tri linear filtering MIGHT make it look better for you...well, try

no, it depends on a persons tolerance for jagged edges , mines very low.
