Dolphin, the GameCube and Wii emulator - Forums

What' screen resolution do you have dolphin set to?

Quote:Hmmm, did some comparisons today, and did discover that fractional, while using SSAA 4x, does produce the same visual quality as 1x at SSAA 4x.

Unless your screen resolution is low it shouldn't.

That funny thing is if you made that "mistake" you would be right. Fractional + no SSAA will yield the same image quality as fractional + 4xSSAA.

I was simply stating two things in my post:

1. Fractional is superior to 1x, period. It's a higher scale so it will always yield better image quality.

2. With a high efb scale 4xSSAA will not change the image quality in any way. It will only improve things if your efb scale is low because of the scale multiplier it adds.

Try comparing fractional + no ssaa to 1x + no ssaa and you'll see that I'm right about number 1. Then try comparing fractional + no ssaa against fractional + 4xssaa and you'll see that I'm right about number 2. I would not make either claim if they couldn't be easily proven.

I'm not trying to attack you or anything, just pointing out these facts so that you can understand what's going on.

Based on the dimensions of that screen shot the game is probably running at 1024 x 576. At that resolution any difference between them is very small, but you're probably right.

Fractional @ 1024 x 576 + 4xSSAA = 2048 x 1152
1x scale + 4xSSAA = 1280 x 1056

Both are much higher than the output resolution so any difference would be extremely small and difficult to notice.

I usually play at 720p, which is what those screen's were captured at. I only sized them down so I could post them. I could play at 1080p, but I like 720p just fine.

1. So 1280 x 720 right?

Yeah that's right on the edge. Anything higher and you will notice the difference between 1x + 4xSSAA and fractional.

2. You have a 6850, which is easily capable of running games at a high efb scale at 1920 x 1080 without breaking a sweat. So why would you run them at 1280 x 720? Is it because you want to small window so you can monitor other software at the same time?

3. Please do not resize comparison screenshots. Especially when using them for image quality comparison. It destroys their credibility for obvious reasons.

Good points. Here are the un-resized versions at 1080p, and your right, I couldn't see the difference before, but I can see it now. Naw, usually I play at 720p so I can make graphics adjustments if need be is all.

My god that was like night and day....fractional looks way better.
