I am aware of the differences between games designed for PC vs Console, in general PC games are more demanding on the CPU and GPU because they can be, unlike a console PCs arent limited to some cheap 485MHz single core for example.

Dolphin seems to work perfectly with Wii emulation, they all run at 100, but for some reason all Gamecube games are significantly slowed down, and despite adjustments to settings the speed is unaffected.

Gamecube Emulator Dolphin 4.0 Series The Sims

I have tried everything in the Performance Guide ( ) I even disabled EFB Copies altogether and everything else to boost speed and the most simple game I have (The Sims 1) still runs at most 70, the second game in the series The Sims Bustin Out runs around 40, while The Sims 3 for Wii runs at 100.

I can run very demanding computer games like Diablo 3 at maximum settings but I cant run old GC games I am using 4.0 (the latest stable version for Mac) But just now I downloaded the latest development version, 4.0-1478 and I noticed the game has jumped from running between 63-73 on average to 73-85 on average and Sims Bustin Out jumped from around 40 to around 55 (jumping between 30-80 periodically, bringing it from unplayable to playable with a great deal of patience in my book) (very short testing with the dev version) and this is with the same settings.

Either way I dont see how it could possibly be the demands of the game slowing Dolphin down, my CPU is running at 2 and I have a couple unused GB of RAM while the game is running.

The fact that it speeds up simply by using a different version tells me it might be how Dolphin was programmed.

Other games had a more significant impact, Baldurs Gate Dark Alliance jumped from an unplayable 40 to 100 without any lag.

Some games like The Sims 2 Pets doesnt run at all in 4.0 but runs fine but at around 83 in 4.0-1478.

But some games cause Dolphin to crash on both versions (Avatar - The Last Airbender).

If you have any ideas not listed in the Performance Guide let me know.

P.S. All the gamecube games I mentioned run at 100 at the main screen, but slow down during gameplay.

Gamecube Emulator Dolphin 4.0 Full Speed In

Try Wind Waker or TimeSplitters, for example, theyll probably run full speed in your computer and both are GC games.

Now, try to run any Metroid Prime game or The Last StoryXenoblade Chronicles from Wii, even the fastest processors available for Dolphin at moment will suffer some kind of slowdown.

Your CPU is weak for the GC games youre trying to run (that probably are demanding since theyre from EA), and thats the reason you wrongly think GC emulation is more demanding (it doesnt matter if its a Wii or GC game, some are demanding, some not).

Newcomers always come here and think that, and were sick of answering the same question again and again.

For short, PC games need powerful GPU, Dolphin need powerful CPU (specifically, models with higher IPC rates, so, avoid AMD CPUsAPUs at any cost).

If you want more complete answers, just go in any other similar thread (we have a loooooot of them).

Dolphin uses only two (or three) cores, so, having two CPUs andor 8 cores will not help with speed.

You need a better CPU (in fact, even a single i3 4130 processor would outperform your two current Xeon, and is much more cheap).

Since the weak point here is probably your CPU, the only things you can do is overclocking (although I dont know if thats possible on Mac), upgrading your computer or using old Dolphin versions.

However, keep in mind that they also have bugs that were already fixed in the latest development versions and because of that, they are unsupported.

In other words, if you opt out using anything older than the latest stable release (4.0.2 at the moment), you will get no support from the forums, you will have to deal with any possible issue alone.

An actual Gamecube has a IBM PowerPC Gekko, 485MHz (Single Core Processor), a Wii uses a IBM PowerPC Broadway CPU (single core, clocked at 729MHz), I am using Two 3.2GHz (Ive never before owned a CPU higher) Quad-Core Intel Xeon Processors (8 Processor Cores).
