to my understanding it is like this
gamecube, let say it is vga 640*480
3xIR = 640*3 and 480*3
=1920 * 1440
then the emu downsample that to your monitor res :hd ,fullhd, or 1360*768, 1440*900 etc
and there you go a very nice quality with almost none aliasing
The efb resolution is 640 x 528 not 640 x 480 but other than that yes, that's the general idea.
I got it. I wasn't considering the benefit to anti-aliasing. If you feel like it perhaps you could explain it? Also I know you were screwin' around but my eyes aren't perfect. I never really stopped to look for benefits beyond my native resolution and was thinking more along the lines of what happens when i run windows 7 at a higher resolution. It's just scaled down. I was thinking the same would happen with dolphin.
You're talking about SSAA right?
The openGL and d3d11 video backends use MSAA, the d3d9 backend uses SSAA.
Setting SSAA to 4x is effectively the same thing as doubling the efb scale right now due to the crappy shader being used. 9xSSAA triples the efb scale and provides a slightly better shader but is far to demanding for almost any system. Increasing the internal resolution past your screen resolution continues to sharpen textures and reduce aliasing but the effect diminishes as you continue pushing it higher and higher.
When I changed my IR from 1x to 3x my FPS got better! At first I was hesitant to adjust IR because I thought it was like resolution in video games, more stuff on the screen.
But then I read this topic and it gave me a pretty good understanding of what IR is doing.

That is weird. If I had to guess I would say it made the GPU exit idle state.
Yeah, I was pretty impressed. I have been using Mario Kart Flower Cup as my test. Before the intro to the track was choppy and slow, and the 3..2..1 was around 30 FPS, which is painful I always miss the speed boost, the beginning of the race was 45 - 60, then 60 FPS after.
When I adjusted to x3, it was solid 55 FPS to 60 FPS all the way and speed boost every time. I knew from the beginning that it made a difference.
Also, V-Sync kills my FPS and I have to have it turned off for F-Zero or it'll crash. But I have consistent tearing, its only one tear but its noticeable, and V-Sync gets rid of it at the expense for FPS. Is there anything else I can do to prevent tearing besides V-Sync? Iev tried GAME mode on my TV but does not make a difference.
what does it mean when 1x, 2x, 3x, etc. native do not differ? they each run about the same amount of fps?

It means your CPU is the bottleneck, so you can raise graphics settings without any negative effect on performance.
I have a GTX 570, and I overclock it to 900mhz, and with that, I can run 4x internal with no problems.
