Hi. Im using dx11. And LLE audio. 1920x1080. 1-4x IR
Most other settings at default.
Here is a screen cap with AA at "2 samples"
As you can see, gpu usage is on 40-60% while on punch out menu, as the fight begins gpu jumps to 99% and fps fall below 20..
Turning off AA will make this game run at full speed with any level of IR.
What vps do you get at 1x IR + 4xMSAA and what vps do you get at 4x IR + no AA?
Well, after long testing, I can say that the gpu can handle this game with AA, among others.
With no AA, vps stay at 60 with 1, 2, 3 and 4 IR.
With AA at 4 samples, I get:
-1xIR -> vps 57
-1.5xIR -> vps 54
-2xIR -> vps 35
-3xIR -> vps 26
-4xIR -> vps 23
Maybe some games don´t like IR + AA, or need a better gpu.
You should try Direct3D9. It's faster than Direct3D11. I recommend 2x IR and 9x SSAA.
Something is very wrong here. It's literally impossible for 4xMSAA to have a greater performance hit than doubling your IR.
Well.. it only happens on this game and 3 or 4 more. Others are fine and run at 4xIR and 4 samples AA at solid 60fps.
Ill test the same game with dx9 to see what happens...
Looks like problems could be gpu/backend/msaa implementation.

Actually, no, since Dolphin needs to make use of MSAA in a fairly inefficient way. I don't know if it can actually be this bad, but I wouldn't rule it out.
Why is the implementation inefficient? How inefficient could it possibly be where 640 x 528 with 4 samples is slower than 2560 x 2112 (16 times the resolution)? How could 4xMSAA ever be slower than rendering at 4 times the resolution? Why do you never elaborate on anything unless I ask?
The best option I feel is to set the IR to Window Size and then use AA after that. It's how most PC games render images and the quality ends up great for me.
Yes that's what I do too. This assumes that you have a fast enough GPU for it though.
