So far - yes. I have tested the following games:

Xenoblade - full speed 95% of the time
Wind Waker and Twilight Princess - full speed all the way
Skies of Arcadia Legends - 50% speed (with equivalent VPS drop) with LLE, which I've read is to be expected. 100% with HLE though.

- edit -

Nevermind, I must have misclicked when I turned the VBeam accuracy off, it behaves normally then with appropriate VPS drop and audio issues. It's just LLE draining my CPU. What propelled me to write the post was that the slow down was present even with that option turned off, but it turns out I'm just blind.

I do have another issue though - diagonals on my Rumblepad 2 make Snake walk instead of run when pushed all the way. I'm aware of the square stick option, since the gamepad does have a square stick, but setting it to 100 doesn't alleviate the issue. It seems the only way is to reduce the range of the sticks as well, but it doesn't work consistently, for example, at 65% it works for left+down, but not for right+up and getting it even lower starts to make Snake walk just because the emulated stick is not pushed far enough. But even for higher values the range is well withing the GC pad's circle too, even without enabling the square stick thingie, thus I believe that it's not related to its squareness at all.

- edit 2 -

I enabled input display. The values for walking with range 100 and square stick at 100 are 217:217 for up+right. Any variation (218:216 for example) makes him run, but if they are exactly the same - he walks. Same for 38:38 for left-down. I have "fixed" this issue by setting the range for Y- and X- off by 1% from Y+ and X+, this way it never gets exactly the same numbers and never walks when the sticks are fully pushed. Of course, he walks anyway if I try to get equal values (tried it with 42:42, took a few tries to get the stick just right) on purpose, but that's extremely unlikely to happen during normal gameplay. Anyone knows why he does that for equal values?
I'm getting really, really annoying audio stuttering. I'm following the config images posted. What do you recommend? 965 phenom ii x4 @ 3.8 ghz, 560ti.

You have to either sync to audio with LLE DSP (although your CPU may be a bit too weak for that) or use the new AX HLE DSP from recent SVN revisions.

Sorry, I uh...Can't seem to find the SVN builds anymore. I know they're what I mainly used a few years or something ago but I can't find them now...

Err... go to dolphin-emu.org, click on Download and scroll to development versions?

ah. They used to actually say SVN in the about section of the program, didn't realize it changed that much. Anyway, I've played with settings for 30 minutes and I can make the stuttering go away in the intro logos and communication sessions but that's it. In game it's horrible.

What's your VPS and FPS when it stutters? If it's below 60 then that's the way it's going to be. If it's 60 - did you remember to sync to audio?

FPS is below 60, between 47 and 55 usually. Not sure where the VPS option would be.

Right next to FPS. If you are rendering to the main window it's on the bottom bar and if you are rendering to a separate window it's on its title bar.

Anyway, this is emulation, you have to have exactly 60 VPS for NTSC and PAL60 titles (fps may be 30 or 60 depending on the game, but in Twin Snakes it should be 60) in order for the sound to be all right. In the previous hack-fest of a HLE you may have been able to get away with it a bit, since it wasn't synchronized to anything, but LLE as well as the new AX HLE certainly are. I think with your processor you might be able to pull it off with AX HLE. First you have to check if your graphic settings are not too high - use dx9, disable AA, turn on 1x native res, set EFB copies to texture etc., if you still can't maintain 60-63 FPS/VPS (~63 because sync to audio does that in order to have smooth sound, Twin Snakes emulation is weird like this) then your CPU is simply too weak and you need to upgrade to an Intel since AMD processors are very bad for emulation.

You can also try the accurate VBeam trick (AFAIK it only works with LLE though):

1. UNCHECK "enable idle skipping" in the general tab of the configuration.
2. press RMB on the Twin Snakes icon in the list, select Properties and CHECK accurate VBeam emulation

If it doesn't work, try various combinations of these two checked/unchecked. It should make audio work fine, but you WILL have severe slowdowns ingame anyway, just the audio won't crackle anymore.

I want to run This game smoothly, but i have a slight fps problem and the sound is jumping constantly, im flying blind with this type of emulator so can some one help please?
