Dolphin, the GameCube and Wii emulator - Forums

Hi,

I have a pretty high end system (specs in sig) overclocked to 4.5Ghz cpu and 1866mhz ram respectively.

I was hoping this would be enough to get full speed emulation with LLE audio enabled. Performance is not what I expected:
In Super Mario Galaxy, speed fluctuates from perfect 60 fps in some areas to 40 fps in others.
In Metroid Other M, speed is great but cut scenes stutter for a few seconds before running full speed again.
In Epic Mickey, speed is well below the 30 fps maximum, dropping to 19fps in some areas.

Is it a configuration issue? Here are my general settings:
enable dual core
enable idle skipping
lle on thread
opengl plugin using:
3x native,
pixel shader lighting,
scaled efb,
openmp decoder,
texture cache set to fast,
efb copies set to texture

Anyone getting full speed with lle audio? Please share your specs and config settings!

EDIT: wanted to mention that I'm using Dolphin 3.0, and that frame rates are the same at 1x native scaling

Try the Direct3D9 graphics backend.

thanks for replying. Performance is actually worse with directx for some reason. My system is pretty up to date drivers-wise

so... is that it? dolphin can't run even on a high end system?

It depends on the game. Even my Ivy Bridge 3570K at 4.7ghz, which is better for dolphin then the Sandy Bridge extreme you have, will lag with LLE in some games. Of course, I can handle Super Mario Galaxy with DSP-LLE and EFB to Ram just fine . But even my beast of a machine can't run Skyward Sword with LLE, even with EFB to Texture, otherwise it will slow down at some points in the game or when opening chests.

There is currently no system out there that can run EFB to Ram and DSP-LLE in ALL games. None. That being said, I'm surprised you can't run Mario Galaxy with DSP-LLE and EFB to Texture. I'd think that your Sandy Bridge Extreme chip would be more comparable to an i5 2500K (which can do that) in it's dolphin performance. Huh. Well, the extreme chips weren't designed for gaming...

Have you tried locking threads to cores? The extreme chips are designed heavily for hyperthreading applications, and dolphin prefers per-core performance. Might help.

No its not. Directx9 is fastest and best option to use currently.
That is what you should use,especially when you are troubleshooting problems.
I have i5 2400 which runs at 3.2 andI never get as low as 40 fps in SMG2. I also have nvidia card ( 460 gtx )
Something is wrong with your system.
Are pc games performing as they should ?

I think it's more like DX9 is usually faster than DX11 and OpenGL, but that's not always the case. For some games, people report DX11 running faster, and to a lesser extent people report OpenGL being faster. This varies depending on the game, hardware, and drivers.

What Shonumi said.

Which areas/levels do you get these drops?
In Metroid, which cutscenes?

Direct3D9 is currently not the fastest on kepler though ;p

Are you sure you changed the settings to be the same upon switching backends? If not, Why don't you post the settings you have for your Direct3D9/Direct3D11 plugins, unless they're synonymous with those of OpenGL.
