But it doesn't, that is the point *waits for NV :3*

Shonumi and ExtremeDude2,
I tested this on pc games such as crysis 2, arma 2 etc when I had core 2 duo,and it worked exactly like I said.
For 20% overclock I would get 20% more fps,because these games are very cpu bound ( arma 2 everywhere,crysis 2 only in certain stages,in other its gpu bound )
I didn't really test this with dolphin,so I cant say for sure.
I am interested to hear what various reasons are this is not the case with dolphin

Probably something along the lines of "x86 can run multiple commands at once sometimes, even on one core. If the data from previous commands hasn't done its journey to RAM and back within the clock cycle, it will be delayed from the next one to the one after. Blah, blah, blah time hasn't been sped up, just the CPU has Blah, blah, blah therefore it doesn't scale perfectly" except it would make sense and would probably actually be correct.

Just right click on your game -> porperties and check "Accurate VBeam Emulation"

I tried that. I tried just about every one of the four possible combinations of the two options mentioned in the OP, and they each had problems to varying degrees.

Specifically, I have tried this on Metroid Prime 3 and SMG2. I don't understand it since it seems everyone else has had pretty universal success with this.

Which games are giving you trouble ?l

That's what I would have figured... My GPU should be more than adequate also, right? And it couldn't be memory bandwidth, could it? Seems everyone has something faster than 1333 these days.

Visually, though, these games don't have too much of an issue most of the time. The occasional dropped frames here and there is all I notice. It's mostly the choppy audio that's a bit annoying sometimes. (I'm running at 2X native resolution, fullscreen at 1366x768, 2 AA, 4x AF)

Choppy audio is LLE problem. You should run metroid prime 3 with HLE audio.
You shouldn't be getting choopy sound with LLE in SMG2.
What speed do you get in SMG2 ? I think you should be getting 60 fps
Did you enable lle on thread ?
Did you try directx9 backend ?
Disable AA
Post all of your settings

I'll post my settings when I get home. Yes, I believe I'm using DX9 right now.

I switched to LLE for my "master" settings after I read in the wiki that it can solve many of the choppy audio problems people experience with HLE (and I noticed occasional audio stuttering, so I thought that could be pretty nice).

EDIT: Oh and yeah, SMG2 seems to run at 60 FPS for the most part. Just the (presumably normal) occasional dip to ~50 FPS.

Thanks again for the help so far.

K, I'm replying here a little later than I intended., but here are the changes I've made. Also, I just upgraded to the latest revision, 3.0-716, but no noticeable improvement. Everything not mentioned here is the default setting... including idle skipping being enabled right now:

DSP settings:
DSP LLE recompiler
Volume 54%
Xaudio2 backend

Graphics General:
Direct3D11
ATI Radeon HD 5700 series
Fullscreen resolution 1366x768
Use Fullscreen
Show FPS
Hide Mouse Cursor

Enhancements:
2x Native (1280x1056)
(I disabled AA per your suggestion)
2x AF

I've made no changes under hacks or advanced.

I'm probably stating the obvious here, but I've noticed that the game runs at ~60 fps maybe 70+% of the time, but it does drop to the low 50s or mid/upper 40s on occasion. That's when the audio gets choppy. Expectedly, the lower the framerate, the worse the choppiness. So it definitely seems like a performance issue, but I don't understand why I'm experiencing it with what I would think is a fairly powerful set up.

Your problem is using directx11 I dont know why you were using it-its not default option.
If you thought games will look better they wont-dolphin is not like pc games where usually choosing newer dx revision indeed makes graphic better.
I just tested dx11 with latest revision,not only is it slower then dx9,but this trick I described in this thread does not work with it !
So this is new interesting thing devs should take note of,I dont think graphic backend should affect timings and LLE audio but it seems that it does

Hmmm, ok thanks, I'll give that a try when I get home tonight. I've flipped that option a couple times between 9 and 11, but I can't remember for sure whether I tried these two options with the gfx backend set to 9.

I switched it to 11 because the wiki recommended it for a graphical glitch in some game. I think it was Skyward Sword.

This works for me, thanks!
