Emulator Issues #3381
[Kirby Epic Yarn] Major speed issues
What steps will reproduce the problem?
1. Launch the game and enter a level (poor speed is most consistently on the stage 1 boss - Karuan)
What is the expected output? What do you see instead?
At random times, speed will dip down to about 50% and sometimes just stay there depending on the scene. The entire stage 1 boss fight runs at a steady 60%. Seems like the further you get into the game the slower the levels run.
Dolphin version with the problem? Other Dolphin version without the
Current revs - r6298
32-bit or 64-bit and any other build parameters?
OS version and versions of tools/libraries used?
Please provide any additional information below.
--Behavior is confirmed on the forums.
--Happens with either "Progression Display" on or off - JIT or JITIL. Cannot find any setting that affects these slowdowns.
--This game should not be that taxing. That and I have a fast computer that can run SMG2 full speed (to give you some perspective).

PAL or NTSC? Steady 50? You'd be the only one. What settings other than default are you using? What's your rig? Just because you have an insane machine and can play this game properly doesn't mean that this simple game should be so slow for the majority of users. There's obviously a dolphin issue here.

Hey Skid, can you please reopen? This is a valid issue. Even one of this guy's screenshots shows the game running at about 80% (50 fps out of 60 - it's ntsc).
Take a look at the official thread on the forums - it's full of people experiencing minor to severe speed issues. It's not all the time, but there are slowdowns all over the place (some pretty bad). http://forums.dolphin-emu.com/thread-12607-page-5.html
Also, the fact that r4775 does not exhibit these speed issues proves to me that some thing has happened in Dolphin to cause this game to have irratic speed behavior. There's something going on here and I can't find any setting that affects this issue.

This issue is a bit vague and it's looking like a hyrule field scenario. Maybe if you can find the exact revision that causes the slowdown we can work with it. As it currently stands, we would not know where to start debugging. r4775 might be faster but it is not as compatible.

At skidau : if you want please check issue 2811. The sudden speed reduction is very noticeable in that situation. The table tennis game in Wii sport resort, don't change the visuals so much to guess a problem on the graphics/texture etc. It looks more as a bottle neck on the CPU emulation.
