Bad Dolphin performance on Mac OS X — 10 fps max

[Sevenstar]

Hello, I am having the same problem with my mac, it is the last one as well with the same specification below. In games like Mario Kart Double Dash Im getting around 30-35 fps, Super Smash Bros Melee Im getting a good 60 If im playing against one CPU only, but when I start increasing it to two I get 50, then with three I get 30-32.

I am going to try Bart's way eventually. My only problem its that I cant seem to get my ps3 control working perfectly on win7... Could anyone please tell me if you can get your triggers working, and if you can connect all 4 controls using MotioninJoy Dualshock? or any other way will help as well.

I am running a dual i3 32ghz iMac with 8gb ram with Mac OS 10.6.7 and Windows 7 Pro 64, and I get worse performance in Super Mario Bros Wii in Win7. I'm running Dolphin v 7461 on both OSes.

I've tried all sorts of settings on both OSes and nothing can get SMBW to run at 100fps. Going to try other versions of Dolphin in case something got messed up... Is there something akin to a "latest stable" for Dolphin, something that is known to perform well?

Actually I found a way to get better performance, nearly perfect, but sometimes there are visual glitches. Enabling EFB Copy Texture sped things up dramatically.

I also noticed that Dolphin wasn't using nearly all of my computing resources, actually only about half. I assume there's a weaker link in there somewhere that's preventing it from going quicker because renicing the process didn't help. Is there a CPU Usage limiter that I'm overlooking that would help me get better performance?

Thats like the exact opposite of what happens on my mac. If I enable EFB to texture or ram my frame rates drops dramatically. Do you mind putting up your graphics settings so we can take a look at them?

Actually Mr1-2 efb texture copies copies are normally much faster than ram copies. The only thing I can think of that would make texture copies slower is if you had a piss poor (and I mean REALLY bad) video card with almost no vram bandwidth and an excellent CPU with excellent main memory bandwidth. Even then it's hard to imagine ram copies being faster than texture copies.

Im not saying Ram copies is faster than Texture just that are both extremely slow on my OSX. I used to use bootcamp Windows XP and be able to run Twilight Princess at 40- 50 Fps but now on the same computer just running OsX I can't get above 10 FPS with EFBs enabled and If its disabled i get a graphics glitch.

Those two statements both imply that texture copies are slower for you.

Perhaps you meant to say something different?

Maybe... on my version of Dolphin I have 3 options. I can either have EFB copies disabled OR enabled to Texture or to Cache. The "opposite" of having EFB disabled is to have have EFB enabled to Texture. Things go much faster for me when EFB is disabled and much slower when it is enabled. Does that make more sense?

Yes.
