Frame skipping?

[Typheus]

Since some games run at ~20-30FPS, couldn't enabling a frameskip make them much more enjoyable? Is there one built into the emulator, or is there anyway to do it? I honestly think it'd help a LOT with slow games. 5FPS games...not a chance in hell, unless you want a slideshow :P

Dynamic Recompilation is as far as I know basically a frameskipping.

[Typheus]

yay thanks.

Wait, so then why the hell do some of my games make me get a cramp in my leg from how slow the character walks?

EDIT: I'll take your word for it. I just turned it off and almost had a blood vessel pop from waiting for the Nintendo sign to disappear.

Try disabling "other audio" in the DSP plugin. It will give you a Speed boost

There's so few games that use sound, I just use the NULL one for now :/

Dynarec is a lot more complicated than frame skipping

There is the "skip idle frames" option, however, which will give basically the same effect as a frameskipper on some games.

Parts of some games are even sped up when the FPS is high, and most games run in slow motion when the FPS get low.

I've been told that the emulated CPU and GPU need to work in sync, and that the bottleneck is probably in the emulated GPU.

Is it possible to implement a "frameskip" by letting the emulated GPU do less work on a percentage of the frames? For example, not rendering that frame and instead just use the previous.

Or is the CPU dependent on some sort of feedback from the GPU so that the GPU needs to process each frame?

AFAIK the gpu is not the bottleneck. Think about it. There are some people here running dolphin with a variety of video cards, but there are no difference in speeds. The only difference exist when using Core 2 duos. So one can say, it's most likely CPU limited.

I was told that the emulated GPU was the bottleneck. If the emulation is done by the real CPU the speed wouldn't be dependent on the real GPU.

I still don't think you got the facts right... There is a reason why dolphin uses the dualcore support/approach. It's because it tries to use one of your cores for emulating the GPU and the other one for the Gekko cpu. That's why in aerlier versions people reported that dolphin wasn't using their processors fully. 'cause the GPU core already did his job.

That's at least what i understand.

It varies from game to game. In some games, the GPU emulation really is the bottleneck - in others, it isn't.
