Dolphin Framerate halves when I turn on frameskip.

Hi I'm using the newest version of Dolphin and when I try to play New Super Mario Bros. Wii I get 50% speed but whenever I turn frameskip on it halves the framerate and the game still runs at 50% speed and the game lags. (effectively I cannot speed up the game to full speed no matter what) I've tried tweaking the settings and some of the .ini files and even tried to reinstall it. I've told dolphin over 1 month ago and still no reply. So can someone here please help.
PS My friend has the same PC and he has no problems.

Why did you use Frameskip? Btw your CPU is weak even for NSMB

You are asking why the number of drawn frames per second gets halved if you enable frame skipping? ...

Frame-skipping in other emulators makes games run faster by skipping the rendering of frames. If I use automatic frame skipping in dolphin, some games often run much slower which is really strange.

Framerate and game speed seem to be somehow linked which is not an expected behavior.

Think about what I said. The games don't run slower, I can assure you that. Just because the FPS is lower doesn't mean the game runs any slower.

Fwiw, the frameskipping feature is completely useless for Dolphin because Wii emulation is much more demanding than emulating other systems.

Ok I'll upload a YouTube video to show you what I mean when I get home tonight.

Frame-skipping usually *won't* give you any noticeable performance improvement, especially if the emulation is bottlenecked by your CPU (which I'm quite confident about, especially given how weak your CPU/APU is for modern emulation).
Even if you tell Dolphin to use frame-skipping, the CPU thread STILL has to emulate the same game code, and STILL will be the bottleneck in your situation (you're lowering the graphics throughput without reducing the cost of emulation).

Is that a notebook or laptop? Those aren't the most ideal for GC/Wii emulation, unlike desktops...

ok yeah that'd be right I've got a shitty core at the moment I'll stick to my softmodded Wii then.
