Emulator

--Also, the game ran fullspeed in r4775. But the game is even more unstable in that version (unplayable).

r4775 is not exit on this sutuation!
Maube in next revs developers fix kirby EY

Please test out r6304. If that does not fix it, the problem is probably in the texture cache (r6288).

Just tried it but it's about the same. It looks faster...I'll say that on average during the fight i'm getting about 5 more FPS (so averaging about 60-70% "speed" now). That's with or w/o XFB - does the game even use this?

FYI just tried r6211 and the slowdowns are almost identical. So this has been around for ahwile (not caused by r6288).

As of r6308, the issue is still present - first boss is still about 65% speed.It's better than where it was 50 revs ago, so we are making everything run a lot better. But something is still just holding this particular game back for some reason.

I got 50fps in the first boss, the Dragon :) in both plugins Dx9 and Dx11

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.

Here is some proof, besides the default configuration I just use Dx11 enable safe texture cache, nothing more, ahh, Also I play in full screen at 1024 * 768

My PC:

Cpu : i3 at 3.8 GHz
Ati HD 3650
2Gb RAM

Here it is the second boss, almost full speed all the time (50-60fps)

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.
