Thanks for the useful guide. I am new to dolphin.
I am trying to figure out what is my system bottleneck from this test
I have a minimal system spec: E6300@2.8G, G41 (yes I know...), 2GRAM
I am getting for FIFA10 a mere 25 fps at 1x
No change until 2.5x, where I get a dramatic drop to 12
Question is:
Does this mean that my bottleneck is the CPU and no matter which high-end GPU I upgrade to, I will always get max 25fps? (I am ok with 1x just would like to increase fps)
tNX

Yes.
On Zelda Twilight Princess, I'm getting 30FPS all the way up to 2.5x ir then at 3x it drops to 25fps. I've read every post on this thread, some things some users contradict each other. So I was wanting to know what was my bottleneck causing the drop at 3x. According to one thing I read it'd be the CPU then another would mean it was the GPU. I'd like to have this clarified because this machine is a media pc I built for mainly emulation for the living room, it's not on my gaming rig. This media pc I built has the AMD A-10 5800k with the built-in radeon 7660d. I would like to get it up to 4X like on my gaming rig, but if it is the CPU, I wont be able to because I'm not going to replace it. But if its is the GPU, I was prolly gonna put a 7770 or 7850 in it. My gaming rig has 7870 and core i5 3570k and I get 4x ir with every game being at a steady/smooth fps.
If the speed drops after increasing your IR, its a GPU bottleneck, if the speed remains the same on all IR, it's a CPU bottleneck.

Thanks. that clears it up. So the 7660d is limiting me from getting the 30fps at 3x and 4x. I dont know if Ill put an actual gpu in it because that is why I went with the APU for this media pc. 2.5x at 30fps on Twilight Princess is good enough. Even though it looks better on my gaming rig. I had doubts about the AMD a-10, but it has performed great for a living room media pc built for emulation mainly.

Installing a dedicated graphics card might improve some of your CPU-related performance as well, since it would take the stress of graphics calculations off the APU chip (somebody correct me if I'm wrong).
It won't make a significant impact. The only real cpu side performance increase would come from a tiny increase in clock rate from turbocore not having to deal with the GPU power consumption (unless you're using hybrid crossfire). Also in future try not to use the word "stress" in that context since it's difficult to tell whether you're referring to power consumption, processing/throughput, or something else.
Is there any point in using 4x internal resolution over 3x if your using a 1920 x 1080P monitor ?, seeing as 3x has a horizontal resolution of 1920 a 1080P screen wouldn't be able to display 4x properly, in fact it cant display 3x vertically seeing as its vertical resolution is 1584 vs 1080. Would 4x have the same effect as super sampling ?, I'm already using 8x AA.

Actually, it's 2x IR that is the max multiple that "can be displayed correctly" at 1080p.
But, using higher is a thing called "FSAA", the most accurate (and most resource-intensive) form of AA out there (that's viable for realtime rendering, that is, as far as I know). 2x FSAA (4x IR vs 2x IR) uses the same amount of extra samples as 4x SSAA, at an even worse performance hit, and can also be ugly (read: I've never seen FSAA go above 4x, and 4x looks like 4x supersampling to me). Plus, FSAA cannot be used on many graphics cards on the market right now at 1080p in most applications.
But, yes, it will display correctly.
I highly recommend that, if you're using 8x MSAA (or is it SSAA right now?), you don't use higher than your screen can display, unless you have at least 1.5 GB VRAM and also have a fast GPU core. (that is, unless dolphin doesn't store anything large on the VRAM, in which case you'd probably be able to go 4x on 1GB, but I wouldn't know, since dolphin's not written in my language, and I've never had the need to ask someone)

wat
2x = 1280 x 1056
3x = 1920 x 1584

SSAA is a type of FSAA.
4x IR vs 2x IR = 4x FSAA samples, not 2x
@johnick
Both SSAA and IR raise the internal resolution in dolphin. The only difference between them is which downscaling filter is used. 4x IR will improve image quality very slightly but with MSAA already in place I doubt you would be able to notice the difference. Switching from MSAA to SSAA would be the preferred method to gain further image quality.

Dolphin doesn't use a lot of vram.
You can easily check this yourself without looking at the code by just checking vram usage with a monitoring application while running dolphin.
